A lobsterman, a seaweed farmer and a surfer called for an end to offshore drilling and oil spills such as the one spewing from BP America’s drilling site in the Gulf of Mexico.

They spoke at a gathering of about 30 people on East End Beach in Portland before a half-dozen people stood on their surfboards and paddled them into Casco Bay to symbolize standing up against offshore drilling.

“We are blowing it,” said Nanci Boutet, owner of Aquaholics Surf Shop in Kennebunk.

The event was organized by the Sierra Club.
