Sunseeker Manhattan 55

The Manhattan 55 measures 17.21 m overall on a 4.87 m beam, with a full-load draft of 1.26 m and a half-load displacement of 27,000 kg; hull and superstructure are GRP. These dimensions are identical to the Manhattan 52 Mk2 that preceded it and the Manhattan 56 that succeeded it in 2026 -- all three are the same 17.21 m x 4.87 m platform carried through three successive restyles, not three unrelated hulls. Sunseeker credits its own team as exterior designer and naval architect, with Design Unlimited as interior designer. Motor Boat & Yachting noted the 55's exterior update over the 52 added larger glass windows, carbon-fibre trim elements and stainless steel rails in place of wire guardrails.

Three cabins accommodate up to six guests: a full-beam master en-suite, and a VIP and twin cabin sharing a bathroom, with two guest heads, a shared day head and an optional single crew cabin. The layout runs a galley-aft arrangement with a cockpit bar and an open salon-to-cockpit flow, plus the flybridge and aft 'Beach Club' transom seen across the range.

Sunseeker's own spec sheet lists a single engine option, twin Volvo Penta D13-800 diesels at 800 hp (588 kW) each for 1,600 hp combined, giving a 30-knot top speed, 25-knot cruise and a maximum range of 250 nm at 25 knots. Other reporting describes a second, pod-drive option on the same D13 block -- Volvo Penta IPS1050 -- following the same shaft-or-pod choice already offered on the Manhattan 52. Motor Boat & Yachting's own sea trial recorded a top speed of just under 33 knots with the shaft-drive engines, higher than Sunseeker's quoted 30 knots; both figures are given here rather than one silently preferred.

Sunseeker introduced the Manhattan 55 in 2021 as a restyled successor to the Manhattan 52 on the same hull, and built 103 units before replacing it with the Manhattan 56 at boot Dusseldorf in January 2026. Motor Boat & Yachting's review of the 55 called it 'big, typically bold and luxuriously finished... a useful reminder of Sunseeker's flybridge prowess,' praising the galley-aft layout and cockpit bar; YachtBuyer's Aquaholic review scored it a 5, describing a 'best-in-class flybridge' with 'three good cabins' and 30-knot performance.
