International 110

From SpottingWorld, the Hub for the SpottingWorld network...

The International 110, often just called the 110 is a one-design racing sailboat designed in 1939 by C. Raymond Hunt. The 110 was revolutionary for its time, and it is still raced, and has a competitive Portsmouth yardstick number of 89.3[1].


The 110 is a long, narrow, double ended boat, resembling a sailing canoe. The cross-section from bow to stern is a rectangle with 2" rounded chine corners, and the boat has a plumb bow and stern. The design's stability is provided by a 300 lb (140 kg). bulb keel. The 110 uses a Bermuda rig, with an optional spinnker, and has the rudder mounted far in from the stern. Originally built in plywood, modern 110s are built in fiberglass. Since there is a minimum hull weight, modern lightweight materials offer little advantage, and older wooden hulls can still be competitive. Crew is 2, although 3 can fit, one crew member can use a trapeze rig to place their weight further out during upwind tacking.
