Built by Schwill Yachts in Canada from 1972 to 1983, this compact cruiser represents thoughtful design work by Diller & Schwill for sailors seeking versatility in a trailerable package. The swing keel configuration stands as the boat's defining feature, allowing draft reduction from 4 feet to just inches for shallow water exploration and easy launching. With its fractional sloop rig and fiberglass construction, the DS 20 delivers respectable performance for coastal cruising and weekend adventures. The 170 square feet of sail area provides adequate power for its 1,850-pound displacement, while the 650-pound ballast ensures stability when the keel is deployed. The boat's 18.09 sail area-to-displacement ratio suggests lively sailing characteristics in moderate conditions. The DS 20 excels as a versatile coastal cruiser, equally at home exploring shallow bays or sailing open waters. Its swing keel design makes it particularly appealing for sailors who value the ability to beach the boat or navigate waters where fixed-keel boats cannot venture. The 20-foot length offers genuine cruising accommodations while remaining within trailerable limits, making it an excellent choice for sailors seeking adventure without marina dependencies. This combination of shallow draft capability and seaworthy design created a practical small cruiser well-suited for exploring diverse coastal waters.
