About the Moth Class

The International Moth is one the most popular classes in the world today, with the boat’s streamlined design offering unprecedented thrills for sailors and spectators alike. Unlike many classes, the Moth has an open design allowing for modification and innovation by enterprising sailors.

It’s this evolution that has seen the Moth class evolve into a state-of-the-art foiling boat, flying at high speed above the water. As a dynamic open-design class, the technology used in today’s world-class Moths can be traced back to a few key innovations over the course of the 1900s. 

In 2019, history came full circle when Mounts Bay Sailing Club was chosen to host the International Moth Class World Championships. Competitors from all over the world united for a heated battle of wills and waves on the very same waters where hydrofoils were first used to success.

Features & Benefits of the Foiling Moth

As a development class, the design and features of the popular Moth has evolved over nearly a decade of competitive sailing. The original 1930s moth was a far cry from today’s hydroplaning models, being a heavy, narrow scow or a blunt nosed skiff.

These original scow moths weighed approximately 50 kg, in comparison to the ultra-fast foiling moths in today’s competition boasting less than 10kg of hull weight.
Wings were later added to the Moth boat for greater speed and control. Former Western Australian Premier Richard Court was the first to use the aluminium and mesh wings on his 18ft skiff yachts, a modification that was quickly adopted worldwide.

In the year 2000, local boat builder Brett Burvill revolutionised the class once again, adding hydrofoils to his moth ‘Windrush’ for greater control at racing speed. Brett’s innovation quickly took off and revolutionised dinghy sailing once again, a change that reverberated across international sailing. These lifting hydrofoils on the daggerboard and rudder of the International Moth elevate the entire hull above the water to minimise drag, allowing for unprecedented speed and agility.

Racing in the Foiling Moth

The foiling technology first seen at this Mounts Bay event has gone on to transform world-class sailing events, including the Americas Cup and Olympic class racing.

The International Moth is considered to be the fastest sailing dinghy, reaching speeds of up to 66.5 km/h.
