The Mc31 one design is a 30.02ft fractional sloop built in fiberglass sandwich e-glass by McConaghy Boats since 2014.
The Mc31 one design is an ultralight sailboat which is a very high performer. It is reasonably stable / stiff and has a low righting capability if capsized. It is best suited as a racing boat. The fuel capacity is originally very small.
