''We wanted to Greenpeace Greenpeace," said Cliff Carroll, a wind farm opponent and protest organizer, referring to the use of Greenpeace-style tactics to oppose the group. ''I think we did that."
Greenpeace members and tour visitors took the shouts in stride and waved at the protesters.
''We assumed this was going to happen," said Christopher Stimson, a member of Clean Power Now, a group based in Cape Cod that has joined Greenpeace in supporting Cape Wind. ''But they don't bother us. As far we're concerned, they're irrelevant."
The group windstop.org organized the demonstration against Greenpeace, along with the Massachusetts Fishermen's Council.
Greenpeace had allowed visitors aboard the Arctic Sunrise on Saturday for a tour to promote the project and renewable energy in general.
In August, Greenpeace sent boats to interrupt a visit by Robert Kennedy Jr., a Cape Wind opponent, during an event for the Alliance to Protect Nantucket Sound, which also is fighting the project.
At issue is a plan to build 130 windmills in Nantucket Sound.
Cape Wind Associates plans to erect 417-foot-tall wind turbines, touting the project as a way to meet the region's energy needs in an environmentally friendly way.
Opponents say the massive towers will create a visual blight, and charge that supporters are ignoring some of the project's environmental impacts.
The plan is undergoing an environmental review headed by the US Army Corps of Engineers in cooperation with state and local agencies.
