Sunseeker's reputation was built on going quickly. The Predator 75 in the same current catalogue weighs 103,396 lbs and does 40 knots. Then you get to the 82 Ocean, which is seven feet longer, sixty thousand pounds heavier, and publishes a maximum of 25 knots.
That is not a compromise. It is the entire design brief, stated in a number. Here is what the specification actually says, and what a buyer should do about it.
The numbers, as published
Length overall is 82' 6". Beam is 21' 6", which is close to a quarter of the boat's length and more than several 88-footers on this market carry. Draft is 6' 1", quoted as a maximum at full load, so there is no margin hiding underneath it.
Displacement is 164,531 lbs at half load. That qualifier matters more than it looks: half load is the condition to plan every lift, berth and bridge clearance around.
Tankage is 2,245 gallons of fuel and 396 gallons of fresh water. Accommodation is published as a band: four to five cabins, four to five heads. Power is twin MAN V12-1650s, 1,650 HP a side, 3,300 HP total. Maximum speed is 25 knots.
Why it is slow, and why that is the point
Three thousand three hundred horsepower moving 164,531 lbs is about 50 lbs of boat per horsepower. The Predator 75 carries roughly 33. That is the whole explanation, and the arithmetic is not a criticism of either boat.
What Sunseeker bought with the extra weight is width and tankage. Interior volume on a motoryacht comes from beam far more than from length, and 21' 6" on an 82-footer is what makes a four or five cabin arrangement possible without the interior feeling like a corridor. Carrying 2,245 gallons means a coastal season is not organised around fuel stops.
What it gave up is pace. Twenty-five knots is the lowest maximum Sunseeker publishes for any current model under 130 feet, tied only with this boat's own Enclosed twin. If arriving first is why the brand is on your list, the Predator 75 and the 76 Yacht are the pages you want instead.
The speed figure worth having
Twenty-five knots is the top of the range. The number that will actually shape your ownership sits somewhere below it, at the rpm you settle on and hold for hours at a time, and it is entirely in your control to obtain.
On your sea trial, hold the rpm you actually intend to run at, and have observed consumption at that rpm recorded in the trial report along with the load aboard and the state of the tanks. That single line is worth more than every performance claim in circulation for this model, because it describes your boat, at your loading, at the speed you will genuinely use.
Who the accommodation is drawn for
Read the accommodation section next to the boats above it in the range and something stands out. The 90 Ocean publishes four cabins and four heads plus crew. The 88 Yacht publishes four plus crew. Every Sunseeker in this class from 88' 11" upward is drawn as cabins plus crew.
The 82 Ocean is drawn as cabins. Four to five of them, four to five heads.
That is a positioning statement. This is the biggest flybridge Sunseeker currently draws for an owner who is not obliged to carry a permanent crew, and the flexible four-or-five cabin layout is the natural consequence. If you are an owner-operator, or you run with a captain who goes home at night, that is the reason to look at this boat rather than the 90.
If you do intend to carry crew, the question becomes urgent rather than academic. Ask the dealer to show you, on the general arrangement drawing for your specific hull number, where those people sleep. Do not accept a brochure photograph as the answer, because the four-cabin and five-cabin versions of this interior are not the same boat and the published images do not all show the same one.
Open or Enclosed
The 82 Ocean Enclosed is the same boat. Not similar, the same: identical published length, beam, draft, half-load displacement, engines, fuel, water, cabins, heads and maximum speed. Four of the photographs on the two model pages are the same image file.
The difference is the upper deck, open to the weather on this one and enclosed on that one. That is a decision about climate and about how you use a flybridge across a season, and it is a real decision. What it is not is a decision about how the boat goes, because the two of them go the same way on every figure the builder prints.
What to check before you sign
Draft first. Six foot one at full load, on a hull 21' 6" wide, against your home berth and your regular anchorages.
Water second. Three hundred and ninety-six gallons on a boat that may have five cabins is a genuine ceiling, and a watermaker belongs in the build contract rather than the commissioning list.
Speed third, in the form described above: observed consumption at your rpm, in writing, from your own trial.
And the layout last, because it is the one that cannot be fixed afterwards. Four cabins or five, and where the crew go if you have them.
Cross-shopping outside the brand, the honest comparison set at this length is the Princess Y80 and the Ferretti 800. The 82 Ocean is the widest of the three and carries more fuel than the Princess. Both of the others are faster on paper. That is the trade, and it is worth making if the way you use a boat rewards width more than speed. For a lot of owners at eighty feet, it does.
