The 505 (5.05m in length) is a double-handed boat that incorporates a high performance hull design with a powerful sail plan and one trapeze. The boat is unique in that it has outstanding performance in all conditions. In light air it is quick and responsive, and in breeze it just goes faster. Planing begins in 10 knots of wind and can do so upwind. Rigging can be adjusted to power ‘down’ or power ‘up’ depending on conditions.

The Class Rules are 'One-Design', the sailplan and hull shape are tightly controlled, while the rigging layout, spars and foils are open.
