The International 110 is an American sailboat that was designed by C. Raymond Hunt as a one-design racer and first built in 1939. While most boat designs have numerical designations that reflect their length overall, waterline length, displacement or some other dimensional parameter, the 110 class was named for the sail number that the prototype carried. In 1946 the 110 was developed into the larger 29.83 ft (9.09 m) International 210.
