The Triangle 20 is a Canadian trailerable sailboat that was designed by American Charles Angle as a cruiser and first built in 1961.
[1][2][3] The design was built by Grampian Marine in Canada, from 1961 to 1963, with 75 boats completed, but it is now out of production.
It has a fractional sloop rig, a raked stem, a plumb transom, a keel-mounted rudder controlled by a tiller and a fixed stub long keel, with a retractable centreboard.
[1][3] The boat is normally fitted with a small 3 to 6 hp (2 to 4 kW) outboard motor, mounted in a stern well, for docking and maneuvering.
The head is located opposite the galley on the port side and includes a sink that drains into the toilet.
