About the Us 30

Designed as a competitive one-design racer, the US 30 emerged from an era when class racing on American waters was thriving, and it earned a loyal following among sailors who valued tight, fair competition on the racecourse. Built for performance, this sloop rewards skilled crews who understand sail trim and tactical racing, making it a natural fit for club racing and regional regattas rather than extended offshore passages. With its racing-focused design, the US 30 offers a responsive and lively sailing experience that appeals to those who enjoy pushing a boat to its limits in a fleet setting. The one-design format ensures that results come down to seamanship and strategy rather than equipment advantages, which has helped sustain an engaged owner community over the years. While detailed specifications are limited, prospective buyers researching the US 30 should seek out active class associations, which can be an invaluable resource for connecting with current owners and uncovering the practical details that numbers alone can't convey. For the right sailor, this boat represents an accessible and rewarding entry into competitive keelboat racing.
