Triangle 20
Description
The Triangle 20 (often called the Triangle sailboat) is a 20.5-foot (LOA 20.5 ft / 6.25 m) fiberglass keel/centerboard cruiser designed by Charles Angle in the early 1960s. It was built by Grampian Marine in Canada from 1961 to 1963, with approximately 75 boats completed. The design was also sold in the US and is considered a scaled-down, more trailerable version of Angle’s earlier Amphibi-Con, emphasizing easy trailering, stability, and a balance of daysailing and light cruising capability.
