Additional Information


The Sigma 33 OOD is the higher performance version of the Sigma 33 cruiser-racer design. Despite nominally being a racing design, these boats make equally good - and very fast - cruisers, with a fully fitted cruising interior. 

The Sigma 33 OOD (Offshore One Design) was designed by David Thomas, and introduced in 1978, becoming an immediate success. The original Sigma 33 OOD had a deep fin keel and fractional rig.  From 1981 onwards a 'detuned' cruising version was produced, with less sail area on a shorter masthead rig, and a shallower but heavier fin keel. Although still moderately fast yachts, and excellent boats, these were never as popular as the original OOD versions, which were equally capable as cruising and racing yachts.

About 450 of the two types were built, until production ended in the early 1990s. 'Practical Boat Owner' describe the design as ".... an excellent fast cruiser", and 'Sailing Today' said the design was ".... fast, stable, and of course, a pleasure to sail".  Despite being an old design, Sigma 33s still turn up doing well in almost every major offshore event's race results, and have made long passages as pure cruisers - at least one has circumnavigated and several have crossed the Atlantic. Their heavy weather ability was proved early on as two survived the 1979 Fastnet race.
