Yacht description

 

Following on from the outstanding success of the MC38 One Design, McConaghy Boats brings you the MC31 a High Performance, Grand Prix racer that is true to it’s design brief: fun, fast, and rewarding to sail . Outstanding hull form stability, with a deep draft carbon fin and a heavy bulb combined to provide a low centre of gravity and stability that is unmatched in this size range. The MC38 has demonstrated that with careful design of a powerful hull form and a powerful sail plan, high performance sailing can be exciting in all wind ranges without being taxing on crew and skippers. The MC31 will do the same, it will sail like a much larger yacht upwind in a breeze and light up down wind like a skiff, but be stable enough to stay up right and safe.

The principal behind the MC31 class rules is to provide owners with the thrill of grand prix racing at an affordable price with the guarantee that all owners drive their own boats.

The MC31 features an unprecedented performance driven hull form, and carefully considered systems and deck layout, that enhances the sailing experience, making it ideal for One Design and Club Racing with Offshore Capabilities.

The MC31 was born from a desire to create a boat and class that gave owners and crew the most rewarding time on the water. McConaghy Boats invested  considerable time and effort to ensure that the boat and the class rules delivered on the objectives which other classes had failed to do. McConaghy Boats brings this recipe for success to the MC38’s little brother the MC31
