And now for something very different ...


This radical motoryacht concept challenges us to rethink the way running surfaces and guest accommodations are united.


The HISWAS or ‘hydrofoil small waterplane area ship’ hull offers high-speed, high-stability performance, even in very rough water, and with a considerable range. London-based designer Jonathan Schwinge has suggested a simple tetrahedron-shaped accommodation like this would top it off nicely.
The idea is even more radical than Wally's recently proposed 'WHY'. Can you imagine trying to berth something like this? These renderings suggest an LOA of 24m (80ft) or so, but then the beam would be much the same; and of course the draught restrictions would be something else again.
At speed the hull – shaped a bit like the keel and bulb consiguration of a performance sailboat – would rise up towards the surface. It would be trimmed electronically to maintain an efficient cruise height. The performance aspects certainly make sense. It has long been known that to boost the performance of a monohull dramatically requires either the hull to be taken above the waves or beneath them, as is the case of the submarine; for many years submarines have been faster submerged than on the surface.
A torpedo-like propulsor would deliver fore and aft thrust at the back of the bulb and a rudder would steer from the trailing edge of blade.
At slow speeds or at rest the superstructure would be supported by three hulls on its underside.
The HYSWAS concept is based upon an existing hull design, which has been developed by several companies, most notably the Maritime Applied Physics Corporation in Baltimore, Maryland, USA. Perhaps you have seen its 12-ton 35-knot Quest demonstrator which launched back in ’95; the US Navy funded the research.
