Galatea was the unsuccessful Scottish challenger of the sixth America's Cup race in 1886 against American defender Mayflower.

Galatea, a gaff cutter, was designed by John Beavor-Webb and built in 1885 for owner Lieutenant William Henn, R.N.

After a series of mostly losses in British races, the owner and his wife sailed to New York in the summer of 1886.

Galatea lost both races in the September 1886 America's Cup in New York to the American defender Mayflower.
