Built by Canadian manufacturer Mistral Sailboats Inc. starting in 1978, this compact 21-footer represents an interesting blend of performance and versatility through its lifting keel configuration. The fractional sloop rig and fiberglass construction reflect the era's emphasis on practical, affordable sailing. With a displacement of 2,700 pounds and 770 pounds of ballast, the T 21 strikes a balance between stability and responsiveness that suits both novice sailors and those seeking a manageable day sailer or weekend cruiser. The lifting keel design offers particular appeal for shallow water exploration and trailer sailing, allowing access to anchorages and launching ramps that would challenge deeper-draft vessels. The boat's 280 square feet of sail area provides adequate power for coastal cruising and club racing, while the comfort ratio of 13.15 suggests a relatively stiff ride that prioritizes performance over motion comfort. The capsize screening formula of 2.35 indicates reasonable stability for protected waters and moderate coastal conditions. This design appeals most to sailors seeking an affordable entry into keelboat sailing or those wanting a capable small cruiser for day sailing and short coastal passages. The lifting keel feature makes it particularly attractive for trailer sailors and those operating in shallow waters.
