Notes

When introduced in 1965, the COLUMBIA 50 was the largest production fiberglass sailboat available in the US.
Also sold as bare hull or 'kit' under the SAILCRAFTER name.
Sloop, yawl or schooner rig.
(In the early 1980's, the molds were acquired by P&M Worldwide Inc. which offered the boat in kit form. If any were made is unknown.)
