Designed by John Winslow for the Royal Vancouver Yacht Club. In 1922 Winslow relocated to Seattle, bringing along a small fleet of Kittens to the Seattle Yacht Club. There, a slightly modified design was built by Blanchard Boat Co.
Today there are no known seaworthy Kittens. In 2008 an original Kitten hull was discovered in a shed on Vashon Island, WA. It is believed this hull was one of the first vessels used by the Seattle Yacht Club and built by the Blanchard Boat Company.
The Center for Wooden Boats in Seattle recently (2020) built and launched a new Kitten Class boat from the original plans.
