“The K8 is unlike any sports boat

on the market, simply because all

other boats have been designed

for conventional rigs. The initial

design brief from Advanced Wing

Systems was to create an

exciting sports boat that is easy

to sail with a small crew. The K8

has modern, powerful lines to

take advantage of the extra

power of the wing. The wide

chines provide narrow heeled

waterlines and high stability,

allowing the boat to be sailed

with 3-5 crew.”

Semi Rigid Wing

The SRW consists of two sails (stiffened with

battens) connected to either side of a rotating mast

at the leading edge of the section, and to each

other at the trailing edge. Thickness and asymmetry

are induced by rotation. The mast is rotated away

from the wind such that the leeward side of the

mast moves aft and the windward side of the mast

moves forward. This places the battens on the

leeward side of the foil in compression and the

battens on the windward side in tension.

The compressed side of the foil cambers, with the

amount of camber determined by the angle of mast

rotation. The direction of asymmetry is determined

by the direction of mast rotation. Figure a shows

the wing-sail with no mast rotation set. Figure b

shows the effect of 10 degrees of rotation.

Additional camber can be introduced to the foil by reducing outhaul (see figure c), thus increasing

the camber of both the windward and leeward battens. By control of the mast rotation and the

outhaul tension a wide variety of section shapes can be produced.

To further control shape, the battens can be controlled at the leech to allow the leeward batten to

push (or slip) past the windward batten. This compensates for sail twist, which has the same effect

as increasing mast rotation, since the batten pairs rotate around the mast. This control allows the

upper sections to be substantially depowered by both twisting and flattening. Figure d shows the

effect of 10 degrees of twist. Figure e shows the effect of allowing the leeches to slip past one

another – reducing the thickness and camber of the section. The figures below shows an example

of how shape can be varied through the span of the wing.

This simple system allows the wing to be controlled with ease. It can also be easily hoisted,

lowered and reefed. The system is light and robust and suitable for racing and cruising boats alike.


Sails are the yachting equivalent of the car engine. You can improve the engine

and, sure, your performance will improve. However, to get the most out of it you

may need to tune other aspects. To get the most out of the SRW it is best to look

at the overall system.

Advanced Wing Systems can work with you to optimise new or existing designs

to get the most from the SRW for your application. So whether you have a

cruising multihull or a race bred foiling monohull, we can work with you to

provide the best solution.

“Optimised For SRW” shows your customers that they will get the best!
