The TP52, or the Transpac 52, as it was once known, was conceived in 2001 by a group of West Coast designers and sailors, including Bill Lee, the godfather of fast-is-fun sailing. The class rule specifies a series of limits, a “box” in designer parlance, and encourages finding the fastest corner. For people frustrated by the slower-is-faster nature of measurement rules such as IOR and IMS, it was a breath of fresh air. The early boats were endurance athletes, built for hours, if not days, on one jibe and for surfing long Pacific rollers. They had oversized 28-foot spinnaker poles for distance races, functional offshore interiors, and twin wheels. Most importantly, they were a blast to sail, a boat that worked with the sailors, not against them.
