Dimensions
Princess lists the F54 at 54 ft 4 in / 16.26 m including pulpit, 14 ft 9 in / 4.50 m beam and 4 ft 8 in / 1.41 m draft. Sunseeker lists the Manhattan 55 at 56 ft 6 in / 17.21 m, 16 ft 0 in / 4.87 m beam and 4 ft 6 in / 1.37 m draft. Those differences can affect interior volume, marina fit and Bahamas-oriented draft considerations.
Propulsion
The F54 is offered with Twin Volvo D11 725 or Twin Volvo D13 900 and uses Shaft drive. The Manhattan 55 offers Twin MAN i6 800PS or Volvo Penta IPS-950 with Shafts or pods. Buyers should compare maneuvering preferences, service familiarity and the exact configuration of an individual yacht.
Accommodation
Both models support three-cabin guest layouts for up to six guests. Princess also offers an optional aft single crew cabin on the F54; Sunseeker publishes optional accommodation for up to one crew member on the Manhattan 55.
Performance
Princess publishes a top speed of Up to 34 knots for the F54. Sunseeker publishes Up to 32 knots for the Manhattan 55 and a manufacturer range figure of 230 nautical miles at 21 knots. Published performance must still be interpreted in the context of load, conditions and individual yacht configuration.
Which one fits better?
The answer depends on how the buyer values beam, draft, propulsion, flybridge and main-deck layout, owner-operation, cruising area, service access and individual-yacht condition. Captain's Rose does not declare a universal winner.
