The International 21 stands as the sophisticated, performanceoriented sibling to the venerable West Wight Potter series. While International Marine is best known for the boxy, highvolume hulls of the Potter 15 and 19, the International 21 was designed to satisfy sailors who demanded a sleeker profile and more refined sailing characteristics without sacrificing the brand’s hallmark trailerability. It is a distinct departure from the "pocket trawler" aesthetic, offering a lowprofile cabin trunk, a sharp entry, and a more aggressive sail plan that positions it closer to a sportboat or modern daysailer than a traditional cruiser. Built with the same robust fiberglass techniques as the Potter line, the 21 utilizes a ballasted swing keel to achieve a balance between stability and the ability to be launched in shallow water.
