April 11, 2014 — A Provincetown Center for Coastal Studies research vessel accidentally collided with a North Atlantic right whale Wednesday, prompting the organization to issue a warning Friday to area boaters of a great concentration of the marine mammals in Cape Cod Bay.
The rare species of whale has been flocking to the western shore of Cape Cod Bay and the area around the entrance to the Cape Cod Canal because of large blooms of plankton, said Dr. Charles “Stormy” Mayo, who was on the vessel, the R/V Shearwater.
On Wednesday at 1:49 p.m., the Shearwater collided with the whale, which surfaced directly beneath the boat. The boat was traveling at 9 knots at the time of the collision, Mayo said.

Manufactured by Michigan-based Hovertechnics, the hovercraft is propelled by fans mounted on the stern. Part of the fan thrust is ducted through the double skin hull to lift the craft off the surface on a cushion of air. This lift air is contained under the craft by flexible segmented skirts that keep the air cushion pressure up, which allows it to travel over a variety of terrain from ice to water to marshes.
