About the Atlantic City Cat Boat Sailboat

Built by Mark-O Custom Boats starting in 1980, this distinctive gaff-rigged catboat represents a modern interpretation of traditional American coastal sailing craft. Designer D. Martin created a beamy, shoal-draft vessel that captures the essence of classic catboat design while incorporating contemporary fiberglass construction techniques. The boat's centerboard trunk configuration and modest 5-foot draft make it ideal for exploring shallow bays, harbors, and coastal waters where deeper-keeled boats cannot venture. Its substantial 11-foot beam provides impressive stability and interior volume for a 24-footer, while the single-handed gaff cat rig offers simplicity and ease of handling that catboat enthusiasts have cherished for generations. With 8,000 pounds of displacement and 2,200 pounds of ballast, this design strikes a balance between stability and performance. The comfort ratio of 22.44 suggests a boat optimized for relaxed coastal cruising rather than racing, while the capsize screening value of 2.2 indicates good stability characteristics for protected waters sailing. The 452 square feet of sail area provides adequate power for coastal exploration and day sailing. This catboat excels as a comfortable weekender for couples or small families seeking to experience traditional sailing in waters from the Chesapeake Bay to New England's protected coastlines.
