The International Moth is an eleven foot long, high performance, single handed
racing dinghy. It is proud to be one of the few development classes left
in the world and have very few design rules including no weight limit.
The class encourages innovation just as much as it encourages sailing skill.
It welcomes home boat building and wacky designs, and almost importantly,
it welcomes unconventional
people with open arms. This offical Australian Moth web site has all the

Being a development class, the moth has evolved from a hull in the 1930’s
that could best be described as a heavy, narrow scow or a blunt nosed skiff,
(weighing about 50 kg) to today’s remarkable foilers with hull weights
of under 10 kg,. Designs have run the gamut from wide skiffs without wings,
to lightweight scows, to wedge-shaped hulls characterized with narrow waterlines
and hiking wings out to the maximum permitted beam. Likewise, the sail
plan has evolved from cotton sails on wooden spars, through the fully battened
Dacron sails on aluminum spars stage, to the windsurfer inspired sleeved
sails on carbon masts seen today.
Today's 11 foot single-handed Moths foil in 6 knots and kiss 30 in heavy
air. The current design earns its international name—it is the fusion
of the American Moth Boat, Australian Inverlock, Swiss-inspired hiking wings,
and a hydrofoil from the UK.
