McConaghy build and finish quality ensure strong, fast and identical boats for maximum racing, without the need for maximum crew.

Americas cup acclaimed Harry Dunning partnered with McConaghy Boats to design and build the latest state of the art one design grand prix racer. The engineering has been done right and light with its systems properly integrated into the boat.

The hull, as we'd expect of a 3,200kg 38-footer, is of carbon/E-glass, and CoreCell composite. The custom-quality build McConaghy is known for is visible both inside and on deck.
