Designed by J. "Jopie" Helsen and first launched in 1974, this compact 20-footer represents a thoughtful approach to small boat cruising and daysailing. The swing keel configuration makes it particularly appealing to sailors who need shallow draft capability for exploring gunkholes, beaching, or navigating areas with limited depth, while the retractable keel allows for conventional sailing performance when deployed. With a displacement of 2,000 pounds and 400 pounds of ballast, the Helsen 20 strikes a balance between stability and trailerable weight. The masthead sloop rig carries 181 square feet of sail area, providing adequate power for coastal cruising and weekend adventures. The fiberglass construction offers durability and lower maintenance compared to wooden alternatives of the era. The boat's comfort ratio of 11.98 suggests it's designed more for spirited sailing than heavy-weather passages, while the capsize screening formula of 2.33 indicates reasonable stability for protected waters and near-coastal sailing. Built by Helsen Yachts in the USA, this design caters to sailors seeking a versatile small cruiser that can handle both sailing performance and the practical demands of shallow-water exploration, making it well-suited for coastal cruising, day sailing, and weekend getaways.
