About the Independence 45 Sailboat

Designed by Harwood Ives and built by Cherubinin Boat Company beginning in 1979, this substantial 45-footer represents classic American cruising yacht philosophy of the late 1970s. The Independence 45's long keel configuration and cutter rig reflect a design priority focused squarely on seaworthiness and offshore capability rather than racing performance. With a displacement of 31,000 pounds and a comfort ratio of 39.94, this yacht falls into the heavy cruiser category that appeals to sailors planning extended passages or ocean crossings. The long keel design provides excellent directional stability and the ability to take the ground safely, though at the expense of maneuverability in tight quarters. Her capsize screening formula of 1.66 indicates good stability characteristics for offshore work. The cutter rig offers versatility in varying wind conditions, allowing for multiple headsail combinations that prove invaluable during long passages. While the SA/Displacement ratio of 10.88 suggests moderate sailing performance in light air, the hull's theoretical speed of 8.15 knots provides respectable passage-making potential. This is fundamentally a boat built for serious cruising sailors who prioritize safety, comfort, and reliability over speed, making it well-suited for coastal cruising and offshore voyaging.
