Started by Jensen Marine founder Jack Jensen, (builder of Cal boats).in order to capture more of the east coast USA market. Jensen Marine also had an exclusive design contract with William Lapworth. So a separate company was formed with the design contract given to Gary Mull.
First manufactured in Cosa Mesa California, the operation was moved to Florida in 1981. Both companies were purchased by Bangor Punta in 1973 (later acquired by Lear Seigler). In an attempt to consolidate the sailboat lineup, the company management decided that the Ranger line was no longer needed, canceled Mulls contract, and later had most of the Ranger molds destroyed.

Years in Business: 1970 - 1987
