The Allied Seawind II, often referred to as the Seawind Mark II, represents a significant evolution of the vessel that famously became the first fiberglass sailboat to circumnavigate the globe. Designed by Thomas Gillmer and introduced in 1975, the Seawind II was not merely a revision of the original 30-foot Seawind but a completely new hull and deck design aimed at providing more interior volume and improved offshore stability. While the original Seawind was a compact 30 feet, the Mark II grew to nearly 32 feet with a substantially wider beam of 10 feet 5 inches, making it a much more formidable long-distance cruiser. Built with the heavy-duty scantlings Allied was known for, the Seawind II was primarily produced as a ketch, though a cutter-rigged version was also offered to sailors who preferred a simpler sail plan.
