Designed by Craig V. Walters and built by the renowned Lyman Morse Boatbuilding, this rare 40-footer represents classic Maine craftsmanship from the early 1980s. With only five hulls constructed beginning in 1983, the Seguin 40 stands as an exclusive example of quality fiberglass construction combined with thoughtful design principles. The boat's substantial displacement of 17,200 pounds and impressive 50% ballast ratio create exceptional stability and seaworthiness, making it well-suited for serious coastal cruising and offshore passages. The deep 7.33-foot draft and keel/centerboard configuration provide excellent upwind performance while offering shallow-water versatility when the board is raised. With a moderate sail area-to-displacement ratio of 18.15 and comfortable 28.25 comfort ratio, this masthead sloop prioritizes seakindly motion and steady progress over pure speed. The low capsize screening value of 1.89 indicates strong stability characteristics that inspire confidence in challenging conditions. Lyman Morse's reputation for meticulous construction quality ensures these boats have aged gracefully. The Seguin 40 appeals to discerning sailors seeking a capable, well-built cruiser that balances performance with comfort, though its rarity means finding one requires patience and typically commands premium pricing.
