Sunseeker Names Hull One of Its 134 Superyacht 'Sovereign'

What has actually happened to the Sunseeker 134 Superyacht this year?

Sunseeker unveiled the 134 Superyacht at boot Dusseldorf in January 2026, laid the keel of hull one in March, lifted the finished composite hull from its mould in May, and on 3 September named that hull 'Sovereign' as she moves into systems and interior fit-out at the Portland yard.

The 134 Superyacht is Sunseeker's largest model since it re-entered the true superyacht bracket, and the yard has been unusually willing to publish the boring middle of building one rather than only the reveal and the delivery photograph. Sunseeker's own site marked the May demoulding with images of the raw composite hull suspended between two mobile cranes, unpainted, the yard's construction team visible in the shot for scale. The 3 September update, headlined 'Layer by Layer, a Legacy Begins', carries no press text beyond the title and a hero photograph of the same hull further along in build - a choice that tells a reader the yard is treating this as a running visual diary of the build rather than a one-off announcement.

That cadence matters because a 40-metre composite superyacht normally disappears from public view between keel-laying and sea trials, and an owner considering hull two or three has almost nothing to judge progress against except the yard's word. Sunseeker has instead put four dated, verifiable milestones on the record in eight months: reveal, keel, demoulding, and now a named hull moving into fit-out. None of those on their own proves the yacht will deliver on time, but together they are a harder thing to fake than a rendering, and they are the kind of paper trail BOAT International and YachtBuyer have both been able to independently confirm from yard photography rather than press-release adjectives alone.

What are the Sunseeker 134 Superyacht's real dimensions and numbers?

Sovereign measures 40.5 metres with a 7.9-metre beam and roughly 340 gross tons, carries 10 to 12 guests across five cabins, and is offered with two engine packages: a standard twin MTU set built for range, and an optional larger pair that pushes top speed to 20 knots.

The naval architecture and exterior are in-house Sunseeker work, with Design Unlimited handling the interior under chief design officer Ewen Foster - the same partnership behind the smaller Manhattan and Predator ranges, now scaled up. The owner's suite sits forward on the main deck, ahead of four further cabins on the lower deck; BOAT International's reporting puts guest capacity at up to 12, YachtBuyer's at a firmer 10 across the same five rooms, a gap that most likely reflects convertible berths counted differently rather than a real disagreement about the layout. Crew quarters take up to nine, generous for a yacht this length and a sign Sunseeker is building for full-time private use rather than charter-lite operation.

The standard powertrain is a pair of MTU 12V 2000 M96X diesels, tuned for range over speed: BOAT International and YachtBuyer both independently put endurance at roughly 1,200 nautical miles at a 10-knot cruise, enough for an Atlantic crossing without refuelling. Buyers who want speed instead can order twin MTU 16V 2000 M97L units, which the yard quotes at a 20-knot top end - a genuine choice rather than a single fixed spec, mirroring the same standard-versus-performance split Custom Line is running on its new Navetta 35 this same show season. Tender stowage takes a Williams 565 jet tender plus two jet skis, and the draught is a modest 2.4 metres for a yacht this size, which keeps a reasonable spread of Mediterranean and Bahamian anchorages open to her.

Who is buying hull one of the 134 Superyacht, and does that matter?

Hull one belongs to a West Coast American owner on his third Sunseeker, and Sunseeker says a second 134 hull has already sold ahead of construction, which together read as a real order book rather than a yard building on spec to generate a headline.

A first-of-type hull ordered by a client with two prior Sunseekers already delivered is a materially different signal than a speculative build a yard lays down hoping to sell during construction, which is how several rival yards have filled empty slots this year. It means the specification decisions locked in at contract - engine choice, tender garage, interior finish - were made by someone who has already lived with the yard's product and presumably knows its faults as well as its strengths, rather than by Sunseeker's own marketing team guessing at what a first buyer might want. YachtBuyer's reporting on the March keel-laying separately puts a second 134 hull as sold before its own construction began, which if accurate means Sunseeker has moved two flagship-scale hulls into build on real contracts inside roughly a year of unveiling the model.

Neither BOAT International nor YachtBuyer names the owner beyond nationality and coast, which is normal for a segment where buyer privacy is closely guarded, and Yotters has not been able to independently verify the hull-two sale beyond YachtBuyer's own reporting - a single-sourced claim that belongs on the record as such rather than repeated as settled fact. What is independently confirmed by both outlets and by Sunseeker's own construction photography is that hull one is real, is named, and is now in build past the point a yard would easily walk away from.

Does Sunseeker's ownership change and dealer trouble put this build at risk?

Sovereign's construction has continued on its published timeline through a full change of ownership in July and the collapse of Sunseeker's largest European dealer in early September, which is the strongest evidence available that the flagship build programme is insulated from the retail-side turmoil rather than exposed to it.

Cross Ocean Partners and Cheyne Capital completed their buyout of Sunseeker in July 2026, installing Phil Millar as chief executive, and the yard's largest dealer filed for UK administration on 7 September, forcing Sunseeker to pull European retail sales in-house with days of notice. A hull already under construction on a signed contract is a different exposure than an unsold boat sitting on a dealer's order book: the dealer's collapse affects how future 134s and the newly-unveiled 45M Superyacht are sold and financed, not whether Sovereign's own build contract, agreed before either event, gets built and paid for on its existing terms.

Still, a buyer weighing hull three or four now has to read the yard's health past the render in a way hull one's owner did not have to when he signed. Sunseeker itself has offered no public statement connecting the demoulding milestone to the ownership change or the dealer failure, and neither is mentioned anywhere in the yard's own construction updates - two separate news streams from the same company that a prospective buyer has to reconcile on his own.

What has Sunseeker not published about the 134 Superyacht?

Sunseeker has not published a base price, a standard-engine top speed, or a firm 2027 delivery month for the 134 Superyacht, and no independent sea trial exists for a yacht that is still roughly a year and a half from being finished.

Every hard number in this story comes from the yard's own photography and press materials as reported independently by two trade outlets, not from a published spec sheet or a sea trial report - normal for a yacht 18 or more months from delivery, but worth stating plainly rather than dressing up as more settled than it is. Delivery is publicly targeted for 2027 with no narrower month attached, the standard-engine top speed has never been quoted by the yard even though the 20-knot figure for the optional engines has been repeated across coverage, and no base price has been disclosed for either hull sold so far.

For a buyer this is the honest state of play: a real, photographed hull, a credible repeat-buyer owner, and a construction cadence the yard is choosing to publish in more detail than most rivals bother with - set against no price, no independent performance figures, and a parent company two events into a genuinely turbulent year. Both things are true at once, and a decision to order hull three should be made with both in view rather than either alone.
