Bill Lapworth's unusual design, with motor sailer accommodations, was ahead of its time.
The Cal 46 was introduced in 1967. One reader said he thinks about 10 were built. For several years it was called the Cal Cruising 46. The Cal 2-46, with a redesigned deck, cockpit and interior layout, succeeded it from 1973 until 1976. The Cal 3-46, virtually the same as the 2-46 except for some minor interior changes, was built in 1977 and 1978.
