A must do trip for divers!

Even though the water was a bit chilly this liveaboard was a trip that I’d definitely want to do again and again. The crew worked together so well. It was like we were all a family by the end of the week. The food was delicious. The mantas and the sharks and the dolphins were incredible. At times I wondered if it was all real. The hot tub on top is a nice treat.

Amazing dolphin encounters

PRO: amazing wildlife sightings and interactions, mantas on every dive. Interacting with the dolphins are what dreams are made of! Saw school of hammerhead sharks. Amazing crew (Idris, Alicia). Most dive guides were attentive and excited to point out wildlife. Hot tub was a plus after cold dives CON: older boat, something was always broken (hydraulics for the anchor, clogged toilets, broken ice maker and water dispense), 9 crew for 18 ppl so no one was helping us put our gear on, first liveaboard that didn't clean your room daily even when we had ppl who got sick with norovirus on the trip, food was average

Awesome crew, amazing diving, and well run operation.

Dolphins, hammerheads, tiger shark, mantas, and the wonderfully friendly crew. The food was good. The top deck can get a little fumey while motoring, so I'd encourage the boat to raise the smokestack or otherwise get creative with the exhaust fumes so that its more comfortable to hang out while motoring.

The crew was absolutely wonderful, the diving and competence of the crew were excellent, and the boat operated like clockwork.
