Text: Devised by Van Oossanen Naval Architects and applied by Heesen for the first time in the design of the 65 metre motoryacht, the Fast Displacement Hull Form (FDHF) allows Galactica Star to perform more efficiently over a wider range of speeds than any other yacht in her class.

Text: In naval architecture, an “efficient” hull is one with the least amount of hydrodynamic resistance.
A conventional displacement hull works well at low speeds, but resistance increases sharply at higher speeds. A fast semi-displacement hull, on the other hand, is inefficient at low speeds when the transom tends to sink deeper in the water.

Text: Although the details are a closely guarded secret, the ingenious solution behind the FDHF concept was to take a specific bulbous bow and combine it with a slender fore body and a shallow transom area that is barely submerged. Moreover, the gently rising buttocks that provide the shallow transom mean more room for bigger and more efficient propellers. A mixture of classic naval architecture and the very latest technology, Galactica Star’s innovative hull form is the key to her efficiency and performance.

Text: Van Oossanen Naval Architects worked closely with the Heesen technical team to convert these characteristics into a buildable superyacht, especially as Galactica Star is the first of its kind. The product of this collaboration is a unique hull form that combines the low-speed efficiency of a full displacement motoryacht with the maximum speed associated with a semi-displacement vessel.
