Three cabins are sold with a sea view and the other four are not, which the operator is careful not to blur

The cheapest berth in this collection at USD 330 a night, on the same serious itineraries

The two life rafts seat thirty-five between them, on a boat that carries twenty-six people all in

Every scheduled trip departs even if only one guest has booked, so a solo diver never loses the dates to an empty boat

The four-berth bunk cabin has its own ensuite and air conditioning, so the cheapest berth on board is not the compromise one

Two engines, two compressors and two watermakers, built for divers who care about redundancy

She carries a 44-foot chase boat, so fishing, surf and far shore runs happen without moving the whole yacht

Ten crew for six guests, with recreational scuba equipment already inside the charter rather than rented alongside it

Eighteen crew for eighteen guests, and every junior suite still gets a king bed rather than twins

Up to four hours of spa treatment a day is included in the rate, alongside the SeaBobs and the diving

The Owners Suite is more than twice the floor area of a stateroom, so the lead cabin is a real upgrade rather than a label

The Bugis suite has windows on three of its four walls, and the Sasak opens onto a semi-private captain's deck

Dive gear is included except the computer, the one item you rent separately or bring yourself

The operator caps every departure at ten guests even though the cabins could take more

The Komodo departure asks for Advanced certification and seventy-five logged dives, so the group is filtered before you board

The Komodo program runs seventeen or more dives across eight days, and Raja Ampat twenty-five across eleven

Trips sell as diving or cruising, so snorkellers pay for the boat and buy dives one at a time instead of a package they will not finish

The published navigation list runs all the way to a clinometer, which almost nothing else in this class bothers with

The family suite carries two double beds and splits its toilet and shower into separate rooms

The camera rinse tank is separate from the gear tank, so a housing never queues behind sixteen sets of fins
