Sailors and sailboats of every description will descend on Edgartown and Vineyard Haven this weekend when two big regattas that are mainstay sailing events of summer get under way.

The Edgartown Yacht Club will host its 90th annual regatta, and Sail Martha’s Vineyard will host its annual Vineyard Cup. Both events attract world-class sailors, and the waters from Cow Bay in Edgartown to West Chop in Vineyard Haven will be dotted with colorful sails all weekend.

They came from as near as Oak Bluffs and as far as Denver to compete in the annual Vineyard Cup Regatta, held last weekend on Vineyard and Nantucket Sound and in Menemsha Pond.

Ninety-five boats and 485 sailors participated in three days of racing and three nights of revelry, all in the name of Sail Martha’s Vineyard, the Island’s youth sailing organization.
