The Hysucat has fully asymmetrical demi-hulls with a wide and deep tunnel allowing nearly undisturbed flow over the two hydrofoils of which the
second one near the transom is adjustable via an oil hydraulic cylinder.
This allows the helmsman to adjust the craft's trim to best performance and softest sea keeping, usually a lower craft trim is selected running into headwaves
and a larger trim in following seas to prevent bow steering.
The "Swift" has an overall hull length of 13.716 m (45') and an overall beam of 5.791 m (19'), full load displacement is 22.1 t.
