A source for information
on the long out of production

First launched in 1963 (?) as
a family sized racer cruiser based on the style of the popular
Cal 20, the Cal 28 "Flat Top" was replaced in 1970 by
the "Pop Top" Cal 27.
Designed by C. William (Bill)
Lapworth, the 28 was the 4th design built by Jensen in California.
Originally called The California 28, as were the other early models,
the name was soon shortened to Cal. At it's height in the mid
70's Cal/Jensen was one of the largest fiberglass yacht builders
in North America. The Cal line went from the Cal 20 up to the
Cal Cruising 46.
The Cal claim to fame came from
the Cal 40, the first fiberglass sailboat built with a fin keel,
and a separate spade rudder. (The rudder on the 28 as it happens
was the prototype for the Cal 40 rudder *) This configuration
was considered "unsafe" for offshore racing by traditional
yacht designers, but the Cal 40 proved to be a safe FAST design
that beat the stiffest competition of the day. Lapworth and Jensen
soon became known for fast designs in their other models as well.
