The Class40 is a monohull sailboat sea-oriented racing and cruising with a maximum length is 40 feet.
The original goal of the class was to make offshore races accessible to amateur sailors. The success of the class has moved it beyond these parameters, with more and more professional sailors attracted to it.
Part of the attraction of this class is the simple and stringent box-rule, which keeps costs down. It is a class of both amateurs and professionals. There are an ever-increasing number of boats being built in France and abroad.
