About the Ansa 47 Sailboat

Swedish designer Ocke Mannerfelt created this capable offshore cruiser for Ansa Sailing Ab in 1984, combining Scandinavian build quality with practical sailing characteristics. The 46-foot design features a modern fin keel and spade rudder configuration that delivers responsive handling while maintaining directional stability in challenging conditions. With a displacement of 26,000 pounds and substantial ballast ratio, this fractional sloop offers the stability and sea-kindly motion that serious cruising sailors appreciate. The 8-foot draft provides excellent upwind performance while still allowing access to most harbors, making it versatile for both coastal exploration and longer passages. The hull's 36.42-foot waterline length contributes to a theoretical hull speed of 8.09 knots, respectable for extended cruising. The boat's comfort ratio of 33.05 indicates a motion that favors seaworthiness over extreme speed, while the capsize screening value of 1.78 suggests good stability for offshore work. The 1,150 square feet of sail area provides adequate power without being overwhelming for a small crew. This Swedish-built yacht represents solid construction values from an era when European builders emphasized durability and sailing performance over interior volume, making it an attractive option for sailors seeking a proven offshore platform.
