About the Admiral 27 Sailboat

Designed by Richard Carlson and first launched in 1968, this 27-footer represents a thoughtful approach to small boat cruising with its distinctive swing keel configuration. The Admiral 27's retractable keel system makes it particularly appealing for sailors who need versatility in varying water depths, allowing access to shallow anchorages and easy trailering while maintaining respectable sailing performance when the keel is deployed. With a displacement of 4,300 pounds and 1,600 pounds of ballast, this fiberglass masthead sloop strikes a reasonable balance between stability and manageable size. The swing keel design necessarily impacts the boat's ultimate stability compared to a fixed keel equivalent, but the comfort ratio of 16.24 suggests quick motion in a seaway typical of lighter displacement boats. The 336 square feet of sail area provides adequate power for coastal cruising and weekend adventures, while the hull speed of 6.70 knots offers respectable performance for its size. This boat suits sailors seeking an affordable entry into cruising with the added benefit of shallow water capability. The Admiral 27 works best for protected waters, coastal day sailing, and short-term cruising where its swing keel versatility truly shines.
