Jason 35
Description
The Jason 35 is a classic full-keel, cutter-rigged cruising sailboat designed in 1970 by Canadian naval architect Ted Brewer and built primarily by Cooper Enterprises in British Columbia (1972–1984). With a 35 ft LOA (30 ft 6 in LWL), 10 ft 10 in beam, 5 ft draft, and 14,000 lb displacement (6,500 lb ballast), she combines a moderate long-keel hull with a pronounced sheer and canoe stern for excellent seakeeping and directional stability in heavy weather. The standard rig carries 620 sq ft of sail (mainsail + yankee jib + staysail—delivering balanced, easy-to-short-hand performance ideal for offshore or coastal cruising. Below, the interior is warm teak with a traditional layout: V-berth forward, saloon with convertible settees, galley to port, nav station to starboard, and a generous quarter berth aft, comfortably sleeping 5–6. Known for rugged fiberglass construction, a low aspect keel that protects the prop in an aperture, and a reputation for crossing oceans (several circumnavigations logged), the Jason 35 remains a favorite among traditional cruiser enthusiasts. Roughly 120 were built.
