Olivier Racoupeau designed a moderate hull with a large carrying capacity. Under water, the hull bends upwards only slowly, which prevents slamming into the waves. An additional advantage is that the hull thus has a fairly large lateral surface area (the surface area under water, seen from the side). As a result, the hull still offers a reasonable amount of resistance to drift even when the daggerboard is up. Useful under sail in shallow water, but also in small harbours with little draught.
