Operational history

The boat is supported by an active class club that organizes racing events, the ''International 110 Class Association''. In 1994 it was reported that the majority of the 110 racing fleets were in New England, on the US west coast and the US upper midwest. In a 1994 review Richard Sherwood wrote, "this fin-keeler was a breakthrough design of the late thirties. Rule changes, allowing a trapeze, enabled the 110 to win the Keel Division of the One-of-a-Kind Regatta in 1969. She points extremely well, planes on the flat bottom, and goes well downwind, but unless weight is kept well aft the bow tends to bury. Because of the very simple lines, the 110 is easy to build ... The cockpit is small and, with the narrow beam, it is difficult to work off the foredeck."
