[1][2][3] The Invader 36 design was developed into the Frigate 36 in 1968, by shortening the long keel into a stub long keel, adding a centreboard and increasing the sail area.
[1][3] The Invader 36 design was built by Hinterhoeller Yachts in Canada, but the majority were constructed at Belleville Marine Yard, both of which became part of C&C Yachts.
[1][3][4][5] The Invader 36 is a recreational keelboat, built predominantly of fiberglass, with wood trim.
It has a masthead sloop rig, a raked stem, a raised counter transom, a keel-mounted rudder controlled by a wheel and a fixed long keel.
[1][3] The boat has a draft of 5.00 ft (1.52 m) and was factory-fitted with a Universal Atomic 4 gasoline engine.
