Deep wreck dive on the Carthaginian II with a second West Maui reef dive
6 Hours (approx.)
Two dives, Wreck and reef sites
Explore the Carthaginian II wreck off Lahaina on a deep, certified-diver boat trip, then dive a shallower West Maui reef for contrast. Plan on an early start and site changes if conditions require.
You must be a certified diver with at least 25 logged dives. If it has been over two years since your last dive, you must complete a refresher dive or hire a private dive guide. A diver medical history form is required, and some divers must obtain a physician’s release; without it, you can ride as a passenger but cannot dive and will not be refunded.
No refunds for changes or cancellations within 48 hours of check-in unless your spaces are rebooked. Medical release may be required; if required and you arrive without one, you can ride as a passenger but cannot dive and will not be refunded. Dive sites depend on weather; no refunds if sites change.
Bring your certification card, a reusable water bottle, a towel, reef-safe sunscreen, and a jacket for your surface intervals.
Complete the required medical history questionnaire in your waiver. Some divers must also get a physician’s release to participate in scuba diving.
You can ride as a passenger, but you cannot dive and you will not be refunded.

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 🤙🏼🤿
