Sunseeker 90 Ocean Enclosed

The 90 Ocean Enclosed is 88' 11" overall on 23' 6" of beam, with 3,434 gallons of fuel, 400 gallons of fresh water, 181,440 lbs at half load and twin MAN V12-1650s at 1,650 HP a side driving it to a published maximum of 27 knots. On those seven figures it matches the open 90 Ocean exactly.

Two rows do not match, and they are the reason this boat is worth a separate page rather than a footnote. Draft is 6' 5" here against 6' 4" on the open boat, both quoted as maximums at full load. And the accommodation table publishes five cabins and six en-suites plus crew, where the open 90 publishes four cabins and four heads plus crew.

That second difference is a whole extra guest cabin and two extra en-suites on an identical hull, and it is what makes this the accommodation choice in the class rather than the atmosphere one. It is also the thing to have confirmed on the general arrangement drawing for your own hull number before deposit, because a cabin count is the one part of a yacht that cannot be changed afterwards.

Everything else reads as the class does. Displacement is a half-load figure, draft is quoted loaded, and fuel and water are US gallons.

The performance figures are the open 90's figures. Twin MAN V12-1650s, 3,300 HP between them, 181,440 lbs at half load, 27 knots maximum. Sunseeker publishes the same displacement for both boats and the same top speed for both.

Which makes the one difference odd, and worth noticing rather than smoothing over. This boat draws 6' 5" where the open 90 draws 6' 4". An extra inch, on an identical published displacement, on the same hull. Both figures are stated as maximums at full load.

There are ordinary explanations for an inch and no good reason to guess between them. The practical part is what matters: if your berth, your lift or your regular bar crossing leaves you inside a foot of margin, do not settle that inch off a website. Get the draft figure for your hull, in your specification, in writing.

On speed, treat this boat exactly as you would its sister. Twenty-seven knots is the maximum and it is not the speed you will hold for hours at a time. Hold your intended rpm on the sea trial and have observed consumption at that rpm recorded in the trial report, with the load and tank state noted beside it. That line describes your hull at your loading, which is the only version of the number worth planning around.

Fuel is 3,434 gallons and fresh water is 400. As on the open boat, water is the tank that will govern how you actually cruise.

The published table gives five cabins and six en-suites plus crew. On an 88' 11" hull with 23' 6" of beam that is a genuinely dense arrangement, and it is one more cabin and two more en-suites than the open 90 Ocean offers on the same platform. Six en-suites against five cabins also means at least one of those heads is serving something other than a guest cabin, and the general arrangement drawing for your hull is what tells you which.

The beam is what makes an arrangement that dense possible at this length. Twenty-three and a half feet of it over 88' 11" is the widest platform Sunseeker currently builds below the 134 Yacht, and interior volume on a motoryacht comes from beam far more than from length. Five cabins on a 90-footer is a lot of doors; on a narrower hull of the same length it would be a corridor.

The enclosure is the other half of the boat. The upper deck is closed in rather than open to the weather, and that is what the name denotes and what separates this boat from its sister in daily use rather than on paper. Combined with the accommodation, the pitch here is a boat used across a longer season by more people.

Fresh water remains 400 gallons. Spread across five cabins plus crew rather than four, that ceiling gets tighter, not looser. A watermaker belongs in the contract.

The Ocean class offers each length open and enclosed, and this is the pair where the choice has consequences. The two 82s are identical on all ten published rows, so choosing between them is purely about the upper deck. The two 90s are not: this boat publishes an extra inch of draft and a table that reads five cabins and six en-suites plus crew against the open 90 Ocean's four and four. If the class's appeal to you is accommodation rather than atmosphere, this is the boat in it.

Against the 82 Ocean Enclosed beneath it, the step is real in every direction: six feet of length, two feet of beam, 1,189 gallons of fuel, crew accommodation that arrives in the class at this length, and a fixed five-cabin table rather than a four-to-five band.

Outside the brand, the size and layout comparison lands on the Sanlorenzo SL90A at 90' 7" and the Ferretti 940 at 95' 1", which is the nearest published five-guest-cabin arrangement in this group. Both are Italian answers to a brief the Sunseeker approaches from a different direction: 23' 6" of beam here is more than the Sanlorenzo carries, and 3,434 gallons is a bigger fuel load than either.

The consistent Sunseeker Ocean argument applies. It is the wide, deeply tanked, comfortable way to buy at this length rather than the quick one, and at 27 knots it does not pretend otherwise.

This is the Ocean for a full house. The published table gives five cabins and six en-suites plus crew, which is the largest guest arrangement in the class, on a hull with 23' 6" of beam and 3,434 gallons of fuel behind it. If you carry family and guests together, in numbers, across a long season, this is the boat the class was building toward.

The enclosed upper deck fits the same profile. It converts the top deck from a fair-weather space into one that works in shoulder seasons and poor weather, which matters more the more people are aboard and the longer the trips are.

It does not fit you if you are unwilling to do the accommodation homework. The cabin count is the whole argument for this boat over its sister and it is the one part of a yacht that cannot be changed after handover, so anyone buying this model should have the general arrangement drawing for their hull number in hand before deposit. If that is not a conversation you want to have, the open 90 Ocean is the straightforward four-cabin version of the same hull.

It does not fit a shallow-water programme without checking. Six foot five at full load, with no reserve in the figure, on a hull two feet wider than the 82.

And it does not fit an owner who wants pace. Twenty-seven knots is the maximum on the same engines the 82s carry, and the Ocean class is not where Sunseeker keeps its speed.
