The Sea Bird 37 MS is a Canadian sailboat that was designed by Stan Huntingford, Hardin International and Cooper Enterprises as a motorsailer and first built in 1973.
[1][2] The design was built by Cooper Enterprises in Port Coquitlam, British Columbia, starting in 1973, but the company went out of business in 1990 and it is now out of production.
It has a masthead sloop rig, a raked stem, a nearly-plumb transom, a keel-hung rudder controlled by two wheels and a fixed long keel.
One wheel is located in the open, aft cockpit and the other on the starboard side of the enclosed pilothouse.
[2] In a 1984 review in Yachting magazine, writer Chris Caswell described the design as, "the purest motorsailer from this company".
