Originally designed by Cyrus Hamlin and Farham Butler in 1954, this 25-foot fractional sloop represents a classic era of American sailboat design when wood strip construction with fiberglass overlay was becoming the preferred method for quality small craft. With 125 hulls built by Mount Desert Yachts and later Sailstar Boats, the Amphibi Con developed a modest but dedicated following among sailors seeking a capable coastal cruiser. The boat's hybrid keel/centerboard configuration offers versatility that appeals to sailors who want both shoal water accessibility and offshore stability. Her substantial displacement of 3,500 pounds and generous ballast-to-displacement ratio provide reassuring stability, while the moderate sail area delivers predictable performance without being overpowering for smaller crews. Notable design characteristics include a comfortable beam that maximizes interior space without sacrificing sailing performance, and a hull speed capability that makes her suitable for extended coastal passages. The comfort ratio of 15.51 suggests this boat favors cruising over racing, while her capsize screening indicates reasonable stability for protected offshore work. Best suited for coastal cruising, weekend getaways, and protected bay sailing, the Amphibi Con appeals to sailors who appreciate traditional construction methods and timeless design aesthetics in a manageable package.
