About the 517 Sailboat

Designed by Christian Maury and first launched in 1976, this compact 17-foot sloop represents classic French design philosophy emphasizing seaworthiness and sailing performance in a small package. The centerboard trunk configuration provides versatility for both shallow water exploration and deeper water sailing, making it an excellent choice for coastal cruising and daysailing adventures. With its fractional sloop rig and generous sail area relative to displacement, the 517 delivers spirited performance that appeals to sailors who enjoy responsive handling. The fiberglass construction ensures durability while keeping maintenance manageable for weekend sailors. At just under 800 pounds displacement, this lightweight design planes easily and responds quickly to wind shifts, though the relatively deep draft of 3.54 feet provides good directional stability. The boat's impressive capsize screening number and low comfort ratio indicate it's built more for performance sailing than extended cruising comfort. This makes it ideal for day trips, sailing instruction, or competitive one-design racing where agility matters more than accommodation space. The 517 suits sailors seeking an authentic sailing experience without the complexity of larger vessels, offering excellent value for those prioritizing sailing quality over creature comforts.
