Frequently Asked Questions

Quick Reference Items

Where can I get a copy of the Diver Medical form? Do I need this?

YES, all guests participating in scuba diving must complete the diver medical form ahead of time. Some items in your current or past medical history may require that you obtain a physician’s release form to participate in scuba diving from our boat.  This link takes you to that form and also includes the form you’ll need your doctor to sign if you do need medical clearance to dive.  If a medical release is required, please be sure to email it to us in advance and bring the original to the boat with you.   If you are already on Maui and can’t get a hold of your regular physician, you can also check in with Doctors on Call ((808) 667-7676) or other same-day medical care services on island.

I left my sunglasses/

towel/

GoPro/

bathing suit on the boat. How do I get it back?

We know how it is when you’re ready to go, so look in your rearview mirror as you leave the parking lot; you just might see a member of the crew running behind your car waving your fins at you!  But if you realize you’ve left something behind after you’ve left the boat, you’ll need to come back to the boat to get it.  You can text us to see if we’ve found your item (we usually have). You can then reclaim your stuff at the boat starting at 5:45 each morning until we leave for a charter.  You can also find us around noon as we return from a charter.  And, if you need something shipped back to you, we can do that too.

How can I book a trip on the Maui Diamond?

You’re just a few clicks or a phone call away from underwater adventures! Dive into our website or dial us up at 808-879-9119, and we’ll make sure you’re all set. We promise, there won’t be any sharks on the line.

I want the boat all to myself; do you offer private charters?

You bet your buoyancy! Private scuba, snorkel, whale watch, sunset charters, or even remembrance gatherings – we’ve got you covered. We’ll make the sea your private playground. Just contact us and let us know what you have in mind and we’ll get you a quote right away. Care to learn more about private charters click here

How early should I arrive for check-in?

Arriving fashionably on time is always a good rule of thumb. Check your confirmation email for the precise check-in time for your upcoming aquatic adventure.

Do you offer transportation?

While we don’t offer transportation,  we’re happy to point you in the right direction. Most guests use a taxi, Lyft, or Uber to get to the harbor. Since our check-in time is early, we recommend arranging your ride the day before – morning pickups can be tricky to book last minute!

Where do we park?

Yes, there’s plenty of parking near Slip 23. You’ll need to pay using the machines or posted QR codes. For most charters, plan to pay for 5–6 hours. For trips to Lanai, we recommend covering 8 hours. Here’s the link to pay for parking in case you find yourself on the boat and realize you forgot!

Can we get our waivers done in advance?

YES, get those waivers done ahead of time! When you’ve got your waiver ducks in a row, the check-in process becomes smoother than a dolphin’s glide through the waves. And if you’ve booked for a group, make sure to share the waiver link with your fellow adventurers. It’s like a secret code to unlocking more time on the water and less time on the paperwork. Let’s make a splash together!  Need the link to the waiver?  Click HERE.

I need rental gear. Do I need to come to the shop ahead of time to get fitted?

Nope!  You can forget about the fitting room drama! Just show up at the boat, and we’ll have your gear ready faster than you can say “wetsuit.”  We provide masks, fins, and wetsuits at no extra cost. BCDs and/or regulator sets can be rented for a mere $30 more. Leave your gear at home if you want to save on some baggage fees, and let us gear you up.  By the way, we no longer have a shop – Maui Dreams Dive Co. is like our cool older sibling – we still love them and recommend them for repairs, rentals and training!

What is the maximum capacity of the Maui Diamond and how many people are typically on a trip?

While the Maui Diamond is Coast Guard certified to carry up to 49 passengers or 36 divers, we prefer to keep things enjoyable – with plenty of elbow room! Typically, our charters host around 22 people, creating an intimate and friendly atmosphere. Diver group sizes can range from 4 to 8 divers, ensuring a personalized experience. And if you’re the kind of diver who craves undivided attention, we offer private guides for an additional fee of $299/day. It’s like having your own underwater butler!

How long will my trip last?

Rise and shine, early birds! Morning charters start at 6:15 a.m. and return around noon. During whale season, we might hang out a bit longer because, hey, whales!  If you’ve booked a Lanai trip, we still check in at 6:15, and we get back to the harbor between 2:00 – 3:00 p.m.

Where can I store my personal belongings?

Each diver gets a dry bin under their seat for personal items. Space is limited, so please pack light; we’ll only be out for a few hours!

Can I bring my own food and drinks on board or do you provide refreshments?

We’ve got you covered like a snug wetsuit! We offer juices, sodas, water, and a variety of snacks, from chips to granola bars and trail mix. During longer charters to Lanai, we even roll out the wraps or sandwiches for lunch. Feel free to bring your own refillable water bottle and non-chilly snacks for the journey (no cooler space available). We’ve got the hydration and munchies part sorted!

Is there a bathroom on the Maui Diamond?

Absolutely! Our restroom might just be the fanciest one you’ve ever seen on a dive boat. We take bathroom breaks very seriously.  And speaking of serious, remember: no paper products in the marine head or else the next person’s bathroom break will have to be three steps off the plank!

Do I need to be a certified diver to go on a dive with you?

Yes, absolutely! We like our divers to know their flippers from their fins, so get that certification, and we’ll be ready to dive into the deep blue with you. For certification inquiries, we wholeheartedly recommend Maui Dreams Dive Co.  If you’re not sure whether you want to get certified or not, you can also try it out with an Introductory Dive!

Can beginners join your dive trips?

Absolutely! Newbie divers are like hidden treasures waiting to be discovered. If this is your first ocean dive, you should start with a shore dive before your boat dives. It’s like dipping your toes before cannonballing into the sea. This will help you get acclimated to local conditions and get you weighted properly for salt water, which will make your boat dives with us soooooooooo much better.  We can book your shore dives for you with a great local dive shop – just ask!

What is the minimum age requirement for your dive trips? What about snorkel trips?

Divers joining us should be at least 12 years old.  Divers who are 10 or 11 years old have depth limitations that require a private guide.  We CAN provide private guides for an additional fee and with some advanced notice.  Snorkelers must be at least 8 years old and directly supervised by a parent or guardian at all times.

Are there preprequisites for any of your dives?

Yes, some dives come with an experience-level warning label, so read those carefully. And remember, you can’t be a rusty old anchor – you must’ve been diving within the past two years. To meet this requirement, you may take a refresher with a local dive shop, rent gear and take yourself on a nice shore dive, or book a guided shore dive with a dive shop here on Maui. We can also help you with reservations for that.

Is Nitrox available?

Nitrox enthusiasts, rejoice! We have it available for those certified to use enriched air. Just remember to bring your Nitrox certification card; it’s your golden ticket to the enriched underwater world.

How do you handle divers with DIN regulators?

We usually have DIN adaptors available, but they occasionally go missing, so it’s best to check with us ahead of time. You’re also welcome to bring your own adaptor if you have one. If needed, you can rent a regulator set from us for $30.

What safety measures do you have in place on your boat?

Safety is our middle name—Maui Safety Diamond! We’re equipped with a standard first aid kit, emergency oxygen, an AED, marine radios, life vests, an EPIRB, and a crew that’s CPR and first aid certified. You’re in good hands, or should we say, fins?

Do you have a photographer on board or should I bring my own camera?

Always bring your camera to capture those unforgettable underwater moments! While some of our guides might snap a few pics and share the treasure with you, it’s not a guarantee. So, bring your own shutterbug gear and be the Jacques Cousteau of your own adventure!

Do you offer any special packages or discounts for multiple dives or returning customers?

We sure do! After you’ve enjoyed three dive trips within a single calendar year, you become an official member of our “Frequent Flipper” club.  We just made that up.  But still, this club comes with exclusive discounts for the rest of the year – it’s like unlocking a treasure chest of savings! And if you’re a local, don’t forget to flash your Hawaii state ID; it’s your ticket to some sweet discounts. We love our loyal divers!

Is tipping the crew customary, and if so, what's the recommended amount?

Tipping, the salty sea tradition that warms the hearts of our crew! While tipping isn’t obligatory, it’s a great way to say “thanks a million” to the amazing folks who make your underwater dreams come true. On average, divers tip around $20 per person. And here’s a little secret: we absolutely adore online reviews that name names. So, if a crew member made your day, let the world know! Whether you choose to tip or not, your happiness is our ultimate treasure.

What's the best time of year for diving on Maui?

Ah, the tricky question! The truth is, Maui is the eternal paradise for divers. But if you’re feeling like a rebel, consider factors like visibility, water temperature, and whale-watching season (Jan-April). The general answer is that we’ve got great diving year-round.   During the months of August through October, the water is warmer and there are typically not as many people on the island.  For more specifics, just contact us!

What's your cancellation policy?

We have a 48-hour cancellation policy. You can cancel or reschedule up to 48 hours before your trip for a full refund. Cancellations made within 48 hours are non-refundable.

If you purchase trip protection at the time of booking, you can cancel up to one hour before check-in and receive a refund (minus booking fees and the cost of trip protection).

What is your cancellation policy in case of bad weather or emergencies?

If Mother Nature decides to throw a temper tantrum and we can’t dive, we’ll call it off and offer you a chance to reschedule or get your money back. But remember, rainy days are just nature’s way of saying, “I like my divers wet!” So, if you decide to bail because of weather and you’re inside the 48-hour cancellation period, there be no refunds or reschedules on this ship.

Because money stuff is serious, here it is in plain English:  If we can’t take you diving due to bad weather, we will cancel the charter and offer to reschedule or refund you.  Note:  Rainy days are usually not considered bad weather – we’re gonna get wet anyway – so please know that If YOU decide to cancel due to weather, and you’re inside the 48-hour cancellation period, you will not be offered a refund or a reschedule.

What's the relationship between Maui Diamond and Maui Dreams? I thought they were the same thing!

The scoop is this:  Rachel and Don opened Maui Dreams in 1999.  They took over the Maui Diamond in 2007 and eventually bought that business too.  And because so many people booked the boat through the shop, and the businesses were both owned by the same folks, we were all just one big happy family.  In the summer of 2023, they sold the shop (Maui Dreams) to Javier and Christina, who have their own boat to fill up with divers!  So, what’s the relationship?  Still warm and fuzzy, but we mainly book our own boats now.  And we also still book each other’s! Clear as mud?

How can we help the people of Lahaina and Maui?

First, thank you so much for your kindness in asking.   You can help by coming to Maui; we enjoy and appreciate your visits and look forward to seeing you.  While you are on Maui though, remember that you will likely be around people who are suffering and getting by in the aftermath of the fire.  Please don’t ask people if their homes burned or any other nosey questions. If people want to talk about it, let them bring it up.  For other good info, we recommend this article – an excellent read with suggestions about volunteering and more.  People’s needs and situations are constantly changing, so if you have specific questions on current needs or volunteer opportunities, please contact us directly and we’ll be happy to share the most current information.

Did a Molokini Crater and Nahuna Point dive with Maui Diamond Sea Sports. Everything about them was highly professional and laid back at the same time. The captain and crew were outstanding. One of the crew had great stories and history and was quite hilarious. Would totally dive with them again. Highly recommended!

I had a great time diving yesterday on the Maui Diamond. We were supposed to dive Lana’i Cathedrals but we rerouted to Molokini Crater and Red Hill due to wind and conditions. We still had a great day with 2 diverse dives! They were flexible and communicative about the change of plans in the days leading up to the dive.

Our captain was Don and my DM was Dave. Dave did a great job giving dive briefings and keeping us safe underwater and at the surface. He also went above and beyond helping me set up my kit to make sure it was in good shape for both dives.

Both dives were drift dives / live drops, which I was a little surprised by since I’m used to having a mooring line, but the crew handled everything well and safety was emphasized. My group had 4 divers and I know it can be a gamble but we all happened to align pretty perfectly on air consumption and ability.

I found Maui Diamond off a Reddit thread and I’m happy I booked with them. I would definitely come back for future trips!

Capt. John took us out to the Lanai Cathedrals. Good captain, great positive attitude and sense of humor, while prioritizing safety and patiently navigating some questionable conditions to give the best experience possible. Great crew, too, they really seem to like what they do and enjoy having people onboard. The boat design is nice, too. Able to fit quite a bit of divers onboard without feeling crowded. Diving Lanai was an amazing experience.

If you bring your own gear, note that they have a weird process- they take your gear from you in the parking lot, then they set your gear up for you. Then you board the boat at the docks and depart immediately. With a crowd of people milling around, it’s a bit disconcerting to have a someone disappear with your gear in the midst of mayhem. I really don’t trust strangers to set up my gear for a lot of reasons. I would 100% go diving with these guys again, but I would have to talk to them about them letting me set up my own gear.

Spent three days diving on the Maui Diamond with Captain Ben and guides Don, Joe, and Dave. We had some weather, but Captain Ben stayed on top of it and kept us safe while still finding great spots. The crew was friendly, organized, and helpful between dives, with clear briefings and easy entries and exits. Awesome experience all around. I highly recommend and I’m already looking forward to a return trip.

This was my first time to Maui. I had the time of my life diving with Maui Diamond Sea Sports, from the Cathedrals of Lani to an entire pod of dolphins swimming by us. This was an experience of a lifetime and on my birthday!! Thank you to everyone at Maui diamond sea sports.

The only dive boat based in a harbor! Captains were great, especially when we did live drops and pick ups. Crew were very friendly and helpful. Very accommodating to help me get back on the boat by taking my gear up for me. New knees don't like the weight going up a ladder. Plus, we were always in the #1 group! Maui Diamond boat is able to handle 20 divers and crew easily. Water and sodas, home made banana bread. Eat the one with chocolate chips :-)
Plenty of snacks.
We did 5 days of diving with Maui Diamond. All dives done in a different area. More turtles than big fish! Dolphins played by the boat for a few minutes. The biggest frog fish was Dave! Great impression of one.
Safety is first priority.
Thanks for the memories Maui Diamond, Mahalo:-)

Maui Diamond Sea Sports provided a great experience. I did two days with them, the Lanai Cathedrals by far the best. Boat was an awesome experience. The entire crew was friendly and extremely helpful, rinsing fear at end of dives was a very nice touch. Call outs to Dave and Brian, my DMs for the two days, great job on showing all the cool sites. Luke and Don as our captains, getting us there and back with no issues. Beth and Kim as excellent deck hands. I dive a lot on the east coast, this was by far the best charter experience I have had.

This was my first, yet not my last, dive w Maui Diamond. The entire crew worked hard so divers had an awesome experience. David was dive master of my group. He made certain questions were answered, concerns addressed and he was very qualified for the job. All staff on dive boat and when I placed calls, were well versed in what to expect, professional, fun, funny and proficient. It was obvious they wanted customers to have a great experience and they enjoyed their sport and job as well. I highly recommend this company and all staff! I will be back next year.

Maui Diamond is the best. You're not just going for a dive, you're joining a team that is going to give you the best diving experience on Maui that is possible. The team is deep, experienced, safe, and fun. The boat is awesome (dolphins not guaranteed), the dive, of course, breath-taking, literally. They provide plenty of air. I can't emphasize enough how great the team made the whole group of customers feel welcome and happy. Can't wait to dive with them again.

I dove two consecutive days with Maui Diamond. The crater dives are where it's at! From start to finish, the crew was top notch from the captains and crew to the dive guides. Every thing was perfect. I can't recommend them enough. I will go back to Maui especially to dive with this group. I hear the cathedral dive is excellent as well.

The Maui Diamond is officially my favorite dive boat on island! From the moment you pull up to the slip, you can feel the enthusiasm from the staff. They definitely love to be on the water! The Diamond itself lives up to its name. The boat is beautiful and clean and up top is an area that you can sit near the captain and see everything. The views are absolutely stunning. They provide little bins to keep your belongings in. I brought a small backpack and towel and they fit perfectly.

Diving is so much more fun when your crew is lively and excited to dive. Beth was so helpful with gear and questions, and she continuously checked in asking if I needed anything or wanted any snacks. She’s so sweet! Dave, my guide, was so fun. He was charismatic and funny during his dive briefing and didn’t skip out on safety. He was happy to show critters underwater and even shared his pictures that he took during the dive at the end. I didn’t miss out on the memories even though I forgot my camera.

If you’re a diver coming to Maui and you don’t get on the Diamond, you are absolutely missing out. Such a fun experience and I can’t wait to get back underwater with them! Mahalo Nui Maui Diamond!

First class dive from start to finish! We did a 2 tank dive to Molokini Crater and Nahuna Spine on Maui. Most of the divers were experienced with the exception of a few beginners.

These guys are a 5 star professional crew from top to bottom. Their dive site selection is awesome and with the first dive being the “premiere” dive site (we did Molokini Crater) and the second dive site being very cool but a little more chill (Red Hill was awesome). They have an amazing system of getting all of your gear ready for you whether you’re using their gear or theirs, they set you up at a specific “station” and give you bins to hold all of your gear to keep it organized and from getting wet. They do safety briefings for departure, en route, and before starting the dive, and their guides were knowledgeable and very professional. They had slates to write out what fish species we were seeing and they briefed us on what we might see before getting in the water. They had snacks and drinks on board, a bathroom with a sink, and the boat was very large and gave you multiple spots to sit and enjoy the ride out and back from all different angles.

And when it came time to come into Harbor, the caption (I think his name was Ben) whipped that boat into the spot without even thinking twice. It was truly impressive.

Long story short, these guys are very good at what they do, they are knowledgeable but still fun and laid back, and you always feel like you’re on good hands. 5 stars across the board. And shoutout to our guide Don, who was a really nice guy and got us on some amazing finds at the bottom.

We had the BEST TIME with Maui Diamond! Beautiful first dive at Molokini crater full of life. Loved the pyramid and pennant butterflies on the drop off and our dive guide Dave found the coolest frogfish and a few blue dragon nudibranchs! We also saw a freckled snake eel and a grey reef shark cruised by. Our second dive was a drift dive at red hill and definitely did NOT disappoint. Dave found SO many fun critters for us to see including a dragon moray, jeweled anemone crab, frogfish after frogfish, nudibranchs, sponge crab, devil scorpion fish and of course we were blessed with a huge turtle! If you are on Maui you should DEFINITELY book with Maui Diamond to have a great day with gorgeous dives. Captain Luke was amazing on the helm picking us all up from our drift dive with safety and ease. He was such a badass parking the boat in the wind too! The crew made sure we had plenty of snacks and drinks and also fish ID books on board to identify all the fun sea life we saw! Highly recommend! 10/10!

Excellent company and employees, across the board.

Starting with the office girls you will talk to when you call:

Rachel and Beth. Exceptional. There have been a lot of changes to the safety waivers and what you are responsible to provide as a diver. If you’ve sneezed in the last 12 months you may need a Dr. release. Hyperbole, but not far off and this is the standard for diving now. Both girls were EXTREMELY knowledgeable, pleasant and helpful. Made the jumping through hoops to dive a lot easier. Friendly, engaging and full of the “Aloha” spirit. Even handed me off to another company for a dive I wanted and they didn’t provide. Exceptional customer service.

The dives were an excellent as well. Booked another dive with them as the staff on the boat were equally as good. Captain Ben, Brian, Davex2 and Joe. Fun, accommodating and very safe. The attention to safety was refreshing and appreciated after diving outside the US. Ask Dave to tell jokes between dives. Hilarious. As for “salad” jokes.

Maui Diamond will get my business every time I dive here. Best dive company I’ve worked with in the 30+ years I’ve been diving.

Thanks guys! Looking forward to my next dive with you!!
I made my first boat dive with Maui Diamond 15 years ago as a freshly certified open water diver. I have dived with them dozens of times since. Great crew of knowledgeable friendly experienced dive masters and one of the best dive boats you will find anywhere. The Maui Diamond is a fast spacious dive boat. First class operation in all respects and that's why I keep returning.

We live on Maui. We always dive with Maui Diamond because they’re no ka oi, the best.

Capt. Don delights us with his safety protocols that make us laugh but remember. He pilots through rough chop with smooth ease of experience over 25 years.

The crew is our diving masters. They set up and down our dive gear even wash it. DMs inform us above the sea and guide us below, plus serve snacks and drinks.

Maui Diamond is truly a diamond of “first water”, best quality.

When choosing a dive shop, I look for competence, safety, and hope to get a crew that is fun and warm. Maui Diamond exceeded my expectations in all respects.

Beth was super friendly and accommodative, helped me get a last minute seat on the boat. I called her so many times to check for a spot and I was grateful for her patience and warmth on the phone. On board, she was genuinely excited to have me dive and this made me feel really welcome and was a great start to the trip.

Crew was great and professional. Took procedures and briefings seriously and ensured everyone understood safety measures in place. I felt safe diving with them. The equipment was in great shape.

The dive itself was great. Lanai Cathedrals is an underwater lava tube - so lots of caves to go through. Can be a bit intimidating if you’re a brand new diver with poor buoyancy control. We saw a huge school of dolphins chase our boat which was super fun and set the tone for our second dive.

It’s a long boat ride (90+ mins each way) so something to watch out for if you get sea sick. Also group sizes tend to be large (we had 21 on our boat, 7 per dive master). But Maui only has a couple of boat diving options left after the fires - so this is standard unless you’re going to charter a boat.

Nick was rad, very knowledgeable and we all had a great safe dive both in Molokini and Makena Bay. I loved that he was able to coordinate when other divers were low on air they could safely return to the boat and the rest of us could stay down longer, such a luxury when this is potentially a once in a lifetime trip for many. Also great on boat service to a wide range of divers/snorkelers which made it fun for all!

Booked a 2 tank dive, Beth was very accommodating with rescheduling due to low numbers. The entire crew was awesome! Ernie was our guide and showed us cool spots and got us into all the fish, sharks and even saw an octopus cruising around.

Dove with these guys in March of 2024. Didn’t think to review the experience as I was a new diver at the time. Now with 70+ dives in five different countries (French Polynesia, Maldives, Fiji, Mexico, HI/FL) I feel obligated to share my experience.

This place was hands down the worst dive outfit I’ve ever dove with. Assembly line packed boat of ~30 divers pre-departure took an hour to checkin and verify docs. Plus 30 min safety brief full of pervy dad jokes to even get on the boat. Dives were with people of all mixed experience levels and typically eight divers to one guide. Our guide was too busy chasing other divers. Pretty much dove by myself the whole time and kept loose track of the group. People floating to the surface, dive guide legit disappeared several times. I wish I would have just rented gear and shore dove somewhere else on the island for notably less. Was somewhere $125-140/tank which I more than I pay for long range dives on other Hawaiian islands. Would not dive with them again. Just skip and go snorkel somewhere. I promise you’ll have a nicer time.

Maui Diamond ranks as my #1 dive charter on Maui. Professional service all around from front office to dive staff, all great dm's (DM Dave is awesome), and safety focused without treating every diver like a new diver. Dives were 60 minutes or longer, there was room to explore without having to be right next to each other, dives were never rushed, lots of snacks and drinks. The boat is comfortable, clean, and roomy. Whether you are a beginner, intermediate, or experienced diver you will enjoy great service and diving with Maui Diamond. Fyi, they don't have a storefront but respond promptly to calls and emails.

I can’t recommend Maui Diamond highly enough! From start to finish, the experience was outstanding. The staff were knowledgeable and friendly, and Joe (our divemaster) took the time to get to know us, answer our questions, and ensure that both dives felt special. The team was also incredibly communicative and helpful while planning, responding to all of our questions with patience and care.

If you’re considering diving in Maui, do yourself a favor and book with Maui Diamond. They were excellent, and the dives were awesome - we saw lobster, octopus, sharks, and more!

My husband and I had the best time diving 6 days with the Maui Diamond team during our vacation!

Big shoutout to our DMs Kim, Ernie, Dave, and Nick who were absolutely wonderful and so much fun to dive with.
The entire crew + captains were so kind and accommodating.

We will definitely be back!

I’ve dived twice (so far) with Maui Diamond on their trips to Lanai. The entire crew was awesome. This is an extremely professional operation with captains and guides (like David, Dave, Nick, Beth and so many others) who are passionate about diving and devoted to assuring their guests have every opportunity to share that passion. Plus, the boat we had was perfectly designed. Plenty of space for divers, ample dry storage and really good banana bread and sandwiches. I’ve dived with dozens of companies and rank Maui Diamond among the best.

Absolutely unforgettable 2-tank dive at Molokini Crater! We brought our three boys (18, 16, and 13), all newly certified divers who had just earned their certifications a few weeks before our Maui trip. From the moment we stepped aboard, the crew’s energy, experience and warmth set the tone for the day.

Our dive master, Ernie, was nothing short of exceptional—patient, calm, and incredibly knowledgeable. He guided our boys through every step, making them feel confident and comfortable in the water. The moment we descended, we were surrounded by crystal-clear blue, schools of colorful reef fish, and coral gardens that looked like something out of an aquarium .

Between dives, the captain and crew kept the atmosphere light and fun, sharing tips, stories, and a genuine passion for the ocean. Watching our kids surface grinning ear-to-ear after their very first ocean dives is a memory we’ll treasure forever.

Five stars aren’t enough—this team made our first family dive in Maui truly magical. We hope to be back again soon!

The Maui Diamond Team really makes this a special experience and because of them, this is the second time we have dove with Maui Diamond on our trips to Maui. The first time we dove with Maui Diamond our sons did discovery dives and they were hooked due to the enthusiasm of our captain and dive masters. We returned this year to find the same level of excellence. The knowledge of all the staff and love for what they do shines. The upbeat engaging instructions and introductions from Captain Don to the briefings and care of all of the dive masters. Today we did a two tank dive to Cathedrals of Lani. It is so worth it. The boat is sizable and room to spread out for the crossing. Other amenities on the Maui Diamond are excellent- gear, very comfortable ladders good for rough seas, lots of snacks and drinks (they joked they had a Costco aisle on the boat, they were right) and a clean, and for a marine head, a spacious bathroom. The crew also provided lunch since this was a 6 hour day. The dive masters before, during and after made sure we had everything we needed for a comfortable, but most importantly a safe dive. Our Divemaster Nick was very patient on the first dive as we got acclimated. He found amazing creatures such as the largest species of Eel in the world and guided us through thousands of other species and corals. The Cathedrals dive is especially interesting because it has unique cavern like structures and lots of swim through that refract the light into many colors. The captain and dive masters all helped each other and engaged with all the divers for fun conversation, very grateful to Don, Nick, Beth, Dave and Ernie. Dave also is an avid underwater photographer and shared some great shots with all of us. We are very grateful. We have dove others in Maui and all over the world. They are the best in the business. I would recommend booking multiple days of diving with them if you are planning more than one day of diving while in Maui. I also would recommend them for snorkel and combined Scuba as well as discovery dives (those trying it out before being certified). Truly appreciate the amazing day!

My wife and 2 kids, 13 and 15, just got back from Maui, we went with the Maui Diamond, and it was excellent! We did 2 tank dives at the Lanai Cathedral 2 and Menpachi. Both dives were amazing! Brian was our dive master and he took very good care of us! The captain and the entire boat crew were amazing!! Highly recommend this company!! :) Loved the warm shower as we got out of the water.

Dove molokini crater today with this crew and they were amazing. Kim was the dive master for myself and my son and she took extra care of me since it was my first dive and I was especially nervous about ascending safely…she took the time to do it with me one on one and let me go without her on the second ascent. Amazing first diving experience with my 18 year old son😎

We went on the Molokini Crater and Cathedrals dives and both were excellent. The visibility in Molokini was incredible with so much to see and the Cathedrals were majestic, we made fantastic memories to treasure. The staff are what really made it, Brian was our guide on day one and Ernie on day two. Both my children are newly qualified divers and we felt in such safe hands with both guides, their experience shone through. Beth and Dave are also worth a special mention as such friendly and helpful staff. The boat was really well equipped with the latest diving gear and plenty of drinks and snacks. Such a wonderful experience on both days, would recommend to anyone.

Booked my scuba dive trip with Maui Diamond Sea Sport, was the best choice I made for my scuba trip to the Molikinu Crate in Maui, The trip was amazing, the boat is big, with drinks and snacks, the have everything planned and organize for you, you just show up, and scuba. The crew go above and beyond for you, so you can enjoy your dive to the max. I recommend this scuba center and give Maui Diamond Sea sport a 1000 stars

Second year in a row of incredible diving with a great company. Friendly and professional staff. Comfortable layout. All of the gear we needed was provided. Great stock of snacks and drinks aboard this boat! Amazing memories were made!

Don was our guide this time and he was great! His briefings were professional and he was a great leader through both dives. Dave went around from group to group underwater and took photos of us in action. This was truly the highlight of our trip. It allowed us to focus on the diving without managing a camera.

We highly recommend Maui Diamond to anyone and everyone!

Spacious boat, great crew, all well organized, Nitrox is available.
Maui Diamond Sea Sports saved my trip to Maui.
Came to dive with different company that cancelled dives and was lucky enough to get spot on Maui Diamond, not once but on two different days.
Crew was very professional, put emphasis on safety, boat was stable, food was tasty, and as they advertise, they do try to spoil clients.
As a cherry on the top, we were lucky to encounter whale-shark, a rare sight that I will remember forever.
Needless to say, for my future trips I now know with whom to book Maui/Lanai diving.

Fantastic Boat with an amazing crew who loves what they’re doing and knows all the popular dives sites as well as some hidden gems. We picked a wildcard day and it was amazing. Captain Ben was super friendly and very thorough with the safety briefing. The dive team was well staffed and very organized. We had divemaster Don who was super chill, laid back, always smiling and very thorough on the dive briefings and provided a very clear picture of each dive site and the different things we might encounter at each dive site. If you’re looking for a unbeatable diving experience this is it!!

Maui Diamond Sea Sports was awesome to dive and snorkel with. We chose an outfit whom would allow me to dive and my wife to snorkel. They were 100% professional and took us to the best dive spots in Maui, especially when weather turned and got in the way (Pali coast sites). We saw so much with them (Turtles, eels, octopus, so many fish, starfish, etc.) It was an absolutely epic adventure and would not have been so without Captain Ben whom took us up and beyond and David wrote out fish names underwater on his white board to educate. Very cool experience and I so HIGHLY recommend - I'm going to dive with them again!!!

Great dive experience with Michelle, Dave, and Crew from Maui Diamond. Equipment was in great shape and the boat had plenty of space for the group size. Used aluminum tanks to 3k psi, digital dive computer, normal BC and backup regs. We dove on the 13 June 2025 with the 1st dive down to around 80 to 90ft at Molokini Crater and the second dive at Pu'pu Olai cinder cone around 40-50ft. During the dive notable sealife included baby reef sharks, barcuda, eagle ray, lion fish, sponge crab, plenty of native Hawaiian fish and great coral. Thanks again for the great dive experience!

Fantastic dive guide team and boat ride. Friendly, personable, and professional. Great dive spots and safety briefings. I did two excursions (two different days). First was the Molokini Crater two tank dive. Second day was the Lani Cathedrals two tank dive. Molokini Crater visibility was great. Dive guide pointed out a frog fish and octopus, in addition to some small reef sharks swimming by. Cathedrals was a new experience for me, diving through the lava formations and seeing the rare black coral. Very cool! The second dive for both excursions was a drift dive along the shore rock walls, where we saw eels, turtles, and lots of variety of fish.

What a well organized top notch dive company everyone and everything was on point. I’ve been diving hundreds of times and it’s probably one of the nicest boats I’ve been on. It was a bit tight on space but everything was so organized and function extremely well my Dive Master Dave went above and beyond to make sure I had an amazing dive and I also took great pictures… I’m super careful with my air consumption and he took that into consideration and we had an extra long day while also making sure we were safe. We didn’t see a lot of things on our Dive* today, but he sure did a good job capturing what we did see I would definitely dive with this company again! Thanks _divewithdave_ for the photos
