Cal 30
Description
The Cal 30 is an American cruiser-racer sailboat designed by William "Bill" Lapworth and built by Jensen Marine from 1966 to 1971. Part of the renowned Cal line, it was designed for coastal cruising and competitive club racing under PHRF (typical rating ~150-162), offering a blend of performance, seaworthiness, and moderate accommodations for small families or couples. The boat features a solid fiberglass hull, a fixed fin keel, and a spade rudder, making it responsive yet stable for coastal waters and occasional offshore passages. Approximately 400-500 units were built, and its robust construction and balanced design keep it popular in the used market,
