About the Fun 23 Sailboat

Designed by the renowned French naval architects Joubert & Nivelt and built by Jeanneau beginning in 1982, this compact 23-footer represents classic French approach to accessible sailing. The Fun 23's swing keel configuration makes it particularly versatile for coastal cruising and exploring shallow waters, while still maintaining respectable sailing performance with its fractional sloop rig. At 1,875 pounds displacement with 760 pounds of ballast, the boat strikes a reasonable balance between stability and performance for its size. The swing keel design allows draft reduction for beaching or shallow anchorages, expanding cruising possibilities significantly. With 243 square feet of sail area driving the lightweight hull, the Fun 23 delivers spirited performance in moderate conditions. The boat's comfort ratio of 9.29 indicates a relatively quick motion at sea, typical of lighter displacement designs, while the capsize screening formula of 2.6 suggests reasonable stability for coastal waters. Fiberglass construction ensures durability with minimal maintenance requirements. Best suited for day sailing, weekend coastal cruising, and sailing instruction, the Fun 23 appeals to sailors seeking an affordable entry into keelboat sailing or those wanting a manageable boat for exploring protected waters and shallow cruising grounds.
