Designed by the prolific David Thomas and built by Marine Projects in Plymouth, the Sigma 33 C (Cruising) is the more temperate, cruising-oriented sibling of the legendary Sigma 33 OOD (Offshore One Design). While the OOD version became one of the most successful one-design racing classes in British history, the "C" variant was introduced to appeal to sailors who prioritized ease of handling and access to shallower anchorages without sacrificing the hull’s renowned sea-kindliness. Launched in the early 1980s, the 33 C utilizes the same high-performance hull mold as the racer but incorporates a shorter fractional rig and a shallower fin keel, striking a balance between the spirited DNA of a regatta winner and the stability required for family coastal cruising.
