The Sigma 33 designed by David Thomas proved to be an instant success when introduced in 1978. The concept of a one-design race fleet that is still capable of successfully racing under general handicap rules and being a comfortable cruising yacht appealing to sailors around Europe. The design has proven to be a competent offshore racer with many Sigma 33's still racing competitively in offshore events today. The designs heavy weather performance also makes the yachts attractive to those looking for a rewarding cruiser, several having crossed the Atlantic.
