A great Raja Ampat trip
We've done both Komodo (2019) and Raja Ampat (2025) on the Mermaid I and we've enjoyed both trips very much! Super easy logistics, towels and drinks after each dive (and hot drinks after each night dive!). Long 70 minute dives (60 for night dives) with 4 divers per guide. A plus that they now have Starlink internet also!

Flawless liveaboard in pristine Raja Ampat
From start to finish, this was an extraordinary experience! 29 dives on pristine dive sites with unparalleled marine life diversity. I had the great pleasure of being assigned resident videographer Marcelo as my dive guide. His passion and knowledge of all things great and small in the ocean really enhanced my experience and raised my game as a diver and UW photographer. I dived with the other guides as well and they were all exceptional. During the 8 days of diving we encountered all kinds of macro life imaginable, along with manta rays, sharks, wobbegongs, enormous schools of barracudas and so on. Diving in the mangroves was a definite highlight.
Boat operation is flawless, with an exceptionally friendly crew going the extra mile to ensure a great dive experience, such as dry towels and hot drinks after dives. Very much appreciated. A special shoutout to the cooks onboard who prepared plentiful and varied meals and snacks which were delicious regardless if it was Asian or Western food. The boat itself is in very good condition and the cabins are very comfortable.
All in all, I had an awesome experience onboard Mermaid I and I cannot wait to return to explore other parts of Indonesia.

Mermaid 1 for lots of fun!
Knock, knock...”morning! dive briefing” shouts sweet divemaster Rebecca at our cabin door. We eagerly assemble for continental breakfast & PowerPoint presentation of our next dive site. Cruise director, Joss, talks about what we might see on this dive...no promises, but wow Raja Ampat delivers! Giant mantas, crocodile fish, walking shark, swirling schools of barracuda, massive bumphead parrotfish & striped sweetlips, crazy changing-color cuttlefish, turtles, octopus, wobbegong sharks and much more! We’re on the safety stop of the 1st dive of the day, my computer says it’s only 8:15a and a full breakfast will be ready after a hot shower on deck. If your hair is dry...it’s time to dive, if your hair is wet...it’s time to eat & repeat. The night dives were full of action & our divemaster, Imam, was skilled at finding the unusual critters! Returning to the boat, stewardess, Destry, serves us hot chocolate with a smile. We had 29 amazing dives on our nine night cruise. The helpful Mermaid crew is upbeat, professional & the small ship is very comfortable. Master cabin was worth the upgrade, but deluxe cabins looked fine too. Fun excursion to lookout point to view several islands was worth the climb. We highly recommend the Mermaid 1 ship and look forward to another liveaboard trip with them.
Highly professional organized- it was amazing trip

Great trip to a fantastic location with a great crew
This was my first liveaboard experience since 1990 and it was an amazing trip. The level of service by the crew, both for the diving operation and for the overall comfort of the passengers was great. The crew was extraordinarily friendly and helpful, the food was good and plentiful, Cabins were comfortable and clean, dive briefings were very good and helpful (as an instructor I have a certain professional appreciation for this) and the dive operation was great. As an example, the oxygen percentage of the nitrox varied minimally (between 32.1 and 32.5). The dive sites were spectacular, more so in the Missool area than in the north and the amount of wildlife we saw was the best I have ever seen. I would do the trip on the Mermaid again in a heartbeat.

Absolutely Fabulous!
My daughter and I went on the Mermaid 1 for a 10 day trip to Komodo. Everyone involved was genuinely friendly, fun, helpful, informative, and hard working! The entire dive crew were awesome! Everyone was quick to help you with all the diving details - from getting ready (zipping wetsuits), locating gear, getting on the dingy (Helping get on and putting your fins on for you), getting into the dingy after the dive, and getting off the dingy (Unzipping, Cleaning your wetsuit and gear). The diving itself was obviously fantastic. The food was delicious! It was obvious that everyone genuinely wanted every guest to be happy and have the best time in all facets of the trip! I highly recommend!

Amazing, awesome and incredible don't even begin accurately describe the feelings you get when you are in the presence of such a beautiful creature.
