Sunseeker 134 Yacht

The Sunseeker 134 Yacht is the largest model in the current range and the only one classed as a Superyacht. It measures 132' 8" overall on a 26' 1" beam, draws 7' 10" at full load, and displaces 426,396 lbs at half load. Accommodation is five cabins and five heads, plus crew quarters. Fuel is 6,538 US gallons and fresh water is 1,413 US gallons. Power is twin MTU 12V 2000 M96X, and the yard quotes up to 20 knots.

The step from the 100 Yacht is the largest in the range by a wide margin. Length goes up 34' 5", beam by 38 inches, and half-load displacement from 219,095 lbs to 426,396, an increase of 207,301 lbs. Fuel almost doubles from 3,381 gallons to 6,538 and fresh water nearly triples from 476 to 1,413. Maximum speed falls from 30 knots to 20 on the same engine designation.

The accommodation figure is worth reading carefully. Five cabins and five heads plus crew, against five cabins and six heads plus crew on the 100 Yacht. The flagship publishes one fewer head than the boat 34 feet shorter.

Every image of this boat is a rendering; it is unreleased. It is built at Poole in Dorset.

Sunseeker quotes up to 20 knots for the 134 Yacht on twin MTU 12V 2000 M96X. Twenty knots is a maximum rather than a cruising setting.

The comparison that explains this boat is with the 100 Yacht, which carries the same MTU 12V 2000 M96X designation. The 100 is 219,095 lbs at half load and is quoted at 30 knots. The 134 is 426,396 lbs, an increase of 207,301 lbs, and is quoted at 20. Nearly double the weight on the same power unit family, and ten knots off the top. That is a coherent design decision rather than a shortfall: at this displacement the yacht is asking its engines to move a hull that is a fundamentally different proposition from the 100, and 20 knots on 426,396 lbs is a respectable figure against the segment. The Sanlorenzo SD132 at a comparable length is quoted at 17 knots and the Benetti B.YOND 40M at 14.

Fuel is 6,538 US gallons, almost double the 100 Yacht's 3,381. Draft is 7' 10" at full load, the deepest in the range, and on this brand every draft figure is a maximum at full load. Beam is 26' 1".

One qualifier to hold on to. This is an unreleased design, so its performance figures describe a boat that has not yet been built, run and measured. That is entirely normal pre-delivery, and it is the reason the MTU rating as installed, the rigged weight, the tankage as fitted and observed consumption at cruise belong in your contract and in your trial protocol rather than anywhere else.

Published accommodation for the 134 Yacht is five cabins and five heads, plus crew quarters. Read that against the 100 Yacht, which publishes five cabins and six heads plus crew on a hull 34' 5" shorter, and the point becomes clear: the flagship's extra length has not gone into more rooms. It has gone into the rooms being larger, into crew and service space, and into tankage.

The tankage is the most dramatic figure on the sheet. Fresh water is 1,413 US gallons against 476 on the 100 Yacht, close to three times as much for the same number of guest cabins. Fuel is 6,538 gallons against 3,381. On a yacht of this displacement that is the difference between a boat that is provisioned for extended independent operation and one that is not, and it is a more honest indicator of how the 134 is meant to be used than any layout description would be.

Beam is 26' 1", up 38 inches from the 100 Yacht's 22' 11" and the widest in the range. Half-load displacement is 426,396 lbs.

One thing must be said plainly rather than buried. Every image of this yacht in circulation is a computer rendering. The boat is unreleased, so nobody has walked its interior and everything shown of the finish, the joinery and the flow is design intent rather than an observed room. That is normal at this size and it is not a mark against the yacht, but it means the interior conversation happens over drawings and specification schedules rather than over a walkthrough.

If you are buying at this level, the arrangement drawing and the equipment schedule attached to your hull number are the interior. Read them as such.

The 134 Yacht competes in a segment where the yachts around it are considerably heavier on tankage and considerably slower, and where the Sunseeker's position is best described as the quick one.

The Sanlorenzo SD132 is 133' 6" on a 27' 10" beam, published as ten guests and eight crew, with 11,095 US gallons of fuel and a 17-knot maximum on twin MAN V12s. The Riva 130' Bellissima is 131' 3" on a 25' 10" beam, five cabins and four crew cabins, 4,491 gallons, and 22 knots maximum with a published 19-knot cruise. The Benetti B.YOND 40M is 130' 11" on a 28' 3" beam, five guest cabins with six crew cabins, 17,436 gallons, and a 14-knot maximum on twin MAN V12-1400s.

Against that group the Sunseeker at up to 20 knots is faster than the Sanlorenzo and much faster than the Benetti, and slower than the Riva. On fuel it sits second-lowest at 6,538 gallons, well under the Sanlorenzo and a fraction of the Benetti, which is a coherent pairing with the speed: the Benetti and the Sanlorenzo are built around long-legged, slower operation and carry the tankage to prove it.

Beam is where the Sunseeker gives something away. At 26' 1" it is the narrowest of the four, against 27' 10", 25' 10" and 28' 3". Only the Riva is narrower, and the Riva is the other performance-leaning boat in the set. That is a consistent picture rather than a weakness: this is the faster, narrower, lighter-tanked yacht in a group that mostly is not trying to be.

Read the whole comparison with one thing in mind: the other three are delivered boats and the 134 is still a design. That is the reason the contract, rather than the brochure, is the document that matters here.

The 134 Yacht fits an owner stepping from a large motoryacht into a genuine superyacht platform without accepting displacement-speed operation. At up to 20 knots on 426,396 lbs it is faster than the Sanlorenzo SD132 at 17 and considerably faster than the Benetti B.YOND 40M at 14. If the way you use a yacht involves repositioning quickly rather than passage-making slowly, that is the argument.

It fits an owner who wants the same five guest cabins as the 100 Yacht in much larger volumes, with crew and service space to run them properly. Beam grows 38 inches to 26' 1", displacement nearly doubles, and fresh water nearly triples to 1,413 US gallons against the 100 Yacht's 476. This is a yacht provisioned to stay away, with the same guest count, not a yacht that sleeps more people.

It fits a buyer who is comfortable commissioning rather than purchasing. Every image of this yacht is a rendering; it is unreleased and nobody has walked it. The interior conversation happens over the arrangement drawing and the specification schedule attached to your hull, and the timeline is a build timeline.

It is the wrong boat if you want to stand on the yacht before you commit. The 100 Yacht below it is the only flagship in the range presented in photography rather than renderings, and it is being shown at Cannes in September 2026.

It is also the wrong boat if you need delivered numbers before you sign. On an unreleased design the rating as installed, the rigged weight, the tankage as fitted and the observed consumption at cruise are settled in your contract and in your trial protocol. None of that is unusual at this level, but it does mean the paperwork carries the weight a brochure normally would.
