About the First 435 Beneteau Sailboat

Designed by renowned naval architect German Frers and built by Beneteau from 1984 to 1987, this 43.5-foot sailboat represents a compelling blend of performance and cruising capability from the mid-1980s. The First 435 features classic proportions with a moderate beam of 13.08 feet and a substantial draft of 7.42 feet, indicating serious sailing intentions rather than shallow-water coastal hopping. With a displacement of 23,809 pounds and ballast ratio supporting the fin keel with spade rudder configuration, this masthead sloop offers reassuring stability for offshore passages while maintaining responsive handling characteristics. The sail area of 859 square feet provides adequate power without being overwhelming for a cruising couple. Frers' design philosophy shines through in the boat's balance between comfort and performance, making it well-suited for extended coastal cruising and capable offshore work. The comfort ratio of 31.29 suggests a motion that favors seaworthiness over ultimate speed, while the capsize screening formula of 1.82 indicates good stability for ocean passages. Built during Beneteau's transition into more serious cruising boats, the First 435 earned respect among sailors seeking a proven platform for both weekend sailing and longer voyages across significant bodies of water.
