About the Dogger Sailboat

Designed by renowned Dutch naval architect E. G. Van De Stadt in 1965, this 31-foot masthead sloop represents classic European cruising design philosophy from the mid-1960s. The Dogger's plywood single-chine construction reflects the era's emphasis on practical, affordable boatbuilding methods that still delivered seaworthy performance. With its moderate fin keel and spade rudder configuration, the Dogger strikes a balanced approach between cruising comfort and sailing performance. The boat's substantial displacement of 6,614 pounds, combined with nearly 3,200 pounds of ballast, creates a stable platform well-suited for coastal cruising and intermediate offshore passages. The comfort ratio of 22.36 suggests a motion that favors seaworthiness over speed, while the capsize screening formula of 1.82 indicates good stability characteristics for ocean sailing. Van De Stadt's design philosophy emphasized practical cruising boats that could handle a variety of conditions, and the Dogger embodies this approach. The moderate sail area and conservative proportions make it manageable for small crews while providing enough accommodations for extended cruising. This design appeals to sailors seeking a traditional, well-mannered cruiser with proven offshore capabilities and the charm of classic yacht design.
