The FSWH37 is an innovative Fully Submerged Wings Hydrofoil. Completely built in aluminium alloy , except for the foils which are in high resistance steel, the FSWH37 differs from a traditional hydrofoil for the full immersion of the foils, that reduces the drag coefficient and the effects generated by sea motions, guaranteeing more lift for the same surface size. Key benefits : comfort of passengers in every sea conditions, achievement of very high speed with limited power absorption, reduces fuel consumption, increase of operational days.
