Maui Diamond Sea Sports invites you to discover Maui’s most iconic dive sites—from the crystalline walls of Molokini Crater to the lava arches of the Lanai Cathedrals—aboard a spacious 46-foot vessel designed with divers in mind. ...
Divers rave about the exceptional professionalism and attention to detail here. The crew stands out for remembering everyone's names, handling all the gear setup, providing individual dry boxes for belongings, and offering warm water rinses after dives. Guides like Nick, Dave, Joe, and Don consistently earn praise for their knowledge and ability to maximize bottom time, often letting divers stay down for 60+ minutes. The operation runs smoothly from booking through the actual dives, with Beth frequently mentioned for being helpful and accommodating with scheduling. The dive sites themselves are outstanding, from Molokini's back wall to Lanai's Cathedrals, with regular sightings of octopus, sharks, lobster, and endemic species. What really sets this operation apart is how they handle mixed experience levels, allowing confident divers to explore independently while still providing guidance when needed. One dissenting voice felt the boat was overcrowded with too many divers per guide, but this appears to be an outlier among overwhelmingly positive experiences. Multiple reviewers call this their top dive operator, with many returning trip after trip.
Absolutely incredible dive at the Lanai Cathedral and Sergeant Major dive sits! Dave is the best guide and got us perfectly positioned for every site including a stampede of spinner dolphins! Truly unforgettable day of diving with the Maui Diamond crew 🤙🏼🤿
