Storm S-78's fast displacement hull claims 15-20% efficiency savings

Currently under construction at Storm Yachts’ facility in Heusden, the Storm S-78 is an aluminium, fast displacement cruiser.

It uses Peter Van Oassanen’s Fast Displacement Hull Form (FDHF) which Storm claims is 15-20% more efficient than the equivalent “regular” hull shape at semi-displacement speeds.

Aside from lower fuel costs, other advantages are said to be more space in the hull and therefore the interior, lower noise levels and comfortable sea keeping at all speeds.

A pair of CAT C18 1,150hp engines should power the S-78 to a top speed of 24 knots with a smaller pair of C9 575hp units as an option.

On board there are three ensuite cabins – including a full-beam master – plus crew quarters.

The svelte flybridge has plenty of seating and sunbathing space plus room aft for the boat’s tender. A neat addition is the hot tub on the bow, a rare sight on a boat of this size and a real boost to its “big boat” credentials.

The S-78 is part of a seven-boat range including a 65ft version available in flybridge and wheelhouse guises up to a monster 92 superyacht.
