Most twin models in this market are twins in the way siblings are twins. Similar hull, shared tooling, a few figures that drift apart because the deck moulding changed.
The two Sunseeker 82 Oceans are not that. Put the specification tables side by side and there is nothing to compare, because every number is the same number.
Ten rows, ten identical figures
Length overall, 82' 6" on both. Beam, 21' 6" on both. Draft, 6' 1" on both. Displacement at half load, 164,531 lbs on both. Engines, twin MAN V12-1650s at 1,650 HP a side on both. Fuel, 2,245 gallons. Fresh water, 396 gallons. Accommodation, four to five cabins and four to five heads. Maximum speed, 25 knots.
Ten rows out of ten, identical to the digit, on Sunseeker's own pages.
There is a second piece of evidence that is harder to argue with than a table. Four of the gallery photographs are byte-identical files, published on both model pages. Sunseeker is not merely describing the same hull. It is showing you the same hull.
That is worth establishing carefully, because the obvious suspicion is that a website has copied one boat's table onto another boat's page. It hasn't, and the 90 Ocean pair proves it. Those two share no images at all, and their tables genuinely differ: 6' 4" of draft against 6' 5", four cabins and four heads against five cabins and six en-suites. When Sunseeker's pages differ, they differ. When they match, the boats match.
So what is the Enclosed?
The name is the specification. The upper deck is closed in rather than open to the weather. That is what Sunseeker is selling and, on the evidence of its own published figures, it is the whole of what Sunseeker is selling.
This is unusually clean as buying decisions go, and I would rather present it that way than dress it up. You are not choosing between two boats. You are choosing between two versions of one deck, on a hull that does not change.
What the identity means for the sales conversation
It means two specific claims are unavailable to anybody selling you either boat.
Nobody can tell you the Enclosed is slower, thirstier or more tender because of the weight up top. Sunseeker publishes one displacement for both, one draft for both and one maximum speed for both.
And nobody can tell you it is drier, steadier or more seaworthy either. The symmetry runs in both directions.
If a broker offers you either version of that argument, they are selling you a feeling rather than a figure, and it is worth saying so out loud. The conversation gets more honest immediately.
The decision that is actually yours
It is a calendar decision.
An open flybridge is a fair-weather room. It is wonderful in settled heat and it is unused the rest of the time. An enclosed upper deck is available in shoulder seasons, in wind, in rain, and on the grey days that make up more of a cruising year than most buyers assume while they are shopping in June.
So: where do you keep the boat, and how long is your season? If you run somewhere the sun is reliable and being outdoors is the point, buy the open 82 Ocean. It is the identical boat underneath and you give up nothing measurable. If your season runs from spring to late autumn, or your home waters are as often grey as blue, buy this one, and the decision is not close.
That is the whole of it. Everything else on these two pages is shared.
What to check on either of them
The things worth chasing on the Enclosed are the things worth chasing on its twin, because they are the same boat.
Crew accommodation is the first. Every Sunseeker in this class from 88' 11" upward is drawn as cabins plus crew, and both 82s are drawn as cabins. That is a deliberate signal about the kind of owner these were built for, and it is good news if you run the boat yourself. If a captain and a stewardess are part of your plan, get the general arrangement drawing for your hull number and find their cabin on it before you commit. Do not accept a photograph as the answer, and be aware that with four images shared between the two pages, a picture you are shown may not even be of the variant you are buying.
Fresh water is the second. Three hundred and ninety-six gallons, on a boat that may be specified with five cabins and now has an extra deck of living space in daily use. That number makes a watermaker a build-contract item rather than a commissioning afterthought.
Speed is the third, in the form that is actually useful to you. Hold your intended rpm on the sea trial and have observed consumption at that rpm written into the trial report, with the load and the tank state recorded beside it. That single line describes your boat at the speed you will genuinely run it, which is more than any model-wide figure can do.
Where it sits against the market
At this length the honest cross-shops are the Princess X80, published at 82' 5" and within an inch of this boat, and the Azimut Fly 82 at 81' 4". Both are faster on paper. Neither is as wide, and 21' 6" of beam is what pays for the interior volume here.
Twenty-five knots is the lowest maximum in Sunseeker's current range under 130 feet, shared with the open 82. If that number is a problem, the Predator 75 does 40 and the whole conversation changes. If it is not a problem, then this is a very wide, very well-tanked 82-footer with an upper deck that works in weather, and the only remaining question is the one about your calendar.
