Recreational boat traffic in Vineyard harbors was off during the first weeks of summer, but harbor masters report that all changed last Friday, when all four harbors were suddenly full for Independence Day weekend.

“I don’t know if it is the weather, the price of gasoline and the economy,” said Dennis Jason, Chilmark harbor master. “It could be all three.”

Tisbury police arrested two Bridgewater men this week for attempting to steal a 1,000-pound lead sailboat keel.

Corey M. Dechaine, 19 and James Carroll McFarland, 21, were apprehended in broad daylight on Monday on property off Oak Hill Road used by Gannon and Benjamin Marine Railway for the storage of boat parts.
