AYRS is an organisation which encourages all those
interested in yacht design, to get involved. It
does not matter to the Society if you are a professional
designer or builder, or a DIY enthusiast with your own
ideas about improving yacht design. It is,
however, a fact that AYRS members have over the years
contributed to the development of: the winged keel,
multi-hull design, self-steering gear, hydrofoils and
much more. Speed, efficiency and alternative
propulsion systems are high on the agenda.
Kruschandl - Member AYRS
is dedicated to finding out how to make yachting better
(faster, more fun, whatever you want it to be). Our
members run from sober-sided professional yacht
designers and builders to bearded eccentrics full of
ideas that they cannot make work. From our members have
come the winged keel, modern sailing multihulls,
self-steering gear, sailboards, a flock of successful
sailing hydrofoils, the World Speed Sailing Record
system, etc etc. Now people are taking off with
kiteboats and autogyro-sails, and the first amphibious
of the AYRS is open to anyone interested in yacht
research & development. The AYRS is a registered

strength for stayed and unstayed rigs based on sail area
and wood types.

If you've tried the free version of TurboCAD, you might
like to try this one. It looks a bit complex, but it
does offer three dimensional working.

A serious-looking stab at the subject of multihull
rules - an essay
to shed some light. These rules may be in the name
of safety, however it appears to us that as more red
tape is introduced, hobbyists are less likely to attempt
to design and build their own boats. Provided
persons building their own boats stay in home or
international waters, this may not be a problem.
