Advisory to Mariners Replaces April 11th Notice

Aerial and habitat surveys on April 11, 2008 revealed an unprecedented number of right whales in Cape Cod Bay. With the unusual number of whales, their intensive feeding activities, and their movement over much of the Bay, all of Cape Cod Bay should be considered a High Risk Area for right whales. Vessel operators are strongly urged to reduce speed (less than 10 knots), post lookouts, and proceed with caution to avoid colliding with this highly endangered whale.

Vessels are prohibited by state and federal law from approaching within 500 yards of a right whale. Massachusetts Environmental Police and U.S. Coast Guard are authorized to enforce the 500- yard rule. Fishermen are reminded that the approach rule also prohibits them from starting fishing operations (setting or hauling gear) within 500 yards of a right whale.

We forecast that the conditions of high risk will continue for the next week and that the area of greatest risk of collision lies east of a line between Manomet and Race Point, Provincetown. When right whales depart the area, the advisory will be lifted.
