Elwood Widmer (E. W.) "Skip" Etchells (July 5, 1911 – December 20, 1998) was an American naval architect, boat builder and world championship sailor.

He is best remembered now for the one-design racing boat that bears his name, the International Etchells class, a 30 ft 6 in (9.30 m) keelboat that he designed in 1966.

A graduate of the University of Michigan with a degree in naval architecture, Skip Etchells worked for the Navy in shipyards on the West Coast during World War II.

He and his wife, Mary O'Toole Etchells, also campaigned in Stars for many years, traveling the world and winning regattas in the U.S., Europe, the Caribbean, and South America.

In 1958, they won the Star North American Championships at the Tred Avon Yacht Club.
