The boat

The m32 one design –
A 32 foot carbon catamaran

The M32 is designed to be long lasting and competitive. The one-design class rule makes the M32 and its cutting edge design affordable for many. The M32 cat is sailed by a crew of four to five. It is designed for racing and has speed enough to beat 40-footers.

The M32 is a speed machine and doesn’t need a jib which would just create too much drag reducing both speed and manoeuvrability.

The stripped down M32 sail configuration with a main and a gennaker is just what you need to bring the extraordinary speed and manoeuvrability from an extremely light and stiff platform. The M32 asymmetrical foils create the perfect amount of lift and stability, making the hulls skim the surface.



The sole licensed builder for the M32 is currently Aston Harald Composite in Sweden. They are also selling the boats and any spare parts.

Yachting World describing the boat

“When the World Match Racing Tour chose a high-speed cat as its next one-design racer, it seemed likely to fly out of reach of ordinary sailors. But no, Matthew Sheahan finds her easy to sail”

– From Yachting World‘s article.

Yachts and Yachting Magazine tests the M32

“The aim of the M32 is to bring high octane, full throttle multihull fleet racing to a broader range of abilities and budgets. RUPERT HOLMES travelled to Bermuda to find out more…”
