Effect Ships International in Norway has provided Warship Technology with
preliminary details of its latest design based on the Air Supported Vessel
(ASV) concept, the ‘soft motion monohull with waterjet propulsion’.

catamarans have been tested successfully
with encouraging results with regard to
hull resistance and operational efficiency;
behaviour and capabilities in a sea
state; air cushion motion damping; load

flexibility. Several successful hullforms

available and the company believes that
it is ready to challenge the market for
conventional planing monohulls.
The company’s most recent focus has
been on onboard comfort. As it notes, the
most common high-speed hullforms are
planing/semi-planing monohulls. Most
of these high speed, smaller vessels face Asv soft motion Asv monohull.
