An estimated 400 lobstermen or more left the docks for a rally Wednesday outside the Augusta Civic Center, where the Legislature was meeting, to voice their anger about the proposed development of offshore wind power.

Like South Bristol fisherman Adam Gamage, they say that development is a threat.

“Here we are, we have a very sustainable fishery,” Gamage said, “It’s too bad it’s come to this where they are trying to put an industrialized piece of machinery out in the middle of the ocean (and) they don’t really know what is going to do.”

There is currently a plan by New England Aqua Ventus to build one very large, floating platform with a massive wind turbine mounted on top. It would be located a little more than two miles off Monhegan Island in a site approved by the Maine Legislature more than 10 years ago for that purpose.

The project is designed as a full-size test of a floating platform design from the University of Maine, but also to test how large wind turbines perform in the moving and often harsh environment of the open sea.
