At least 48 sailboats from all over Southeastern Massachusetts are expected to compete tomorrow in the 35th annual George Moffett Memorial Race just outside the Vineyard Haven harbor. The start of the race is shortly after 11 a.m.

For 35 years this race has been seen as a sailors’ salute to the end of summer.

The start of the race is just off East Chop. Sailboats ranging from 16 to 75 feet in length will move between West Chop and East Chop and then cross into Nantucket Sound. By tradition, the course will be decided on the day of the race.

An awards ceremony and gam for participants will take place late in the afternoon at the Vineyard Haven Yacht Club.

Hosted and organized by the Holmes Hole Sailing Association, the race is named for George Moffett, a Vineyard philanthropist who founded Felix Neck Wildlife Sanctuary and was an avid world-class sailor and photographer.

The deadline for sailors entering the contest was last Friday. The weather forecast for the weekend was changeable due to an offshore tropical storm that has affected tides and weather patterns on the Vineyard this week.
