You are advised that the endangered Right Whale inhabits areas along the U.S. Eastern Seaboard. In the U.S. Northeast, right whales inhabit areas within the Ambrose and Boston Harbor traffic lanes in the spring and summer. NOAA has designated Cape Cod Bay and the region east of Cape Cod as Critical Habitat for this species and has identifed Stellwagen Bank National Marine Sanctuary as an additional area of importance. The whales also aggregate in the Precautionary Area within the Great South Channel in the spring. Mariners are requested to post a lookout for Right Whales as they approach these areas and to minimize their exit and entrance speeds to the extent possible to maintain safe handling of the vessel in the channels and precautionary areas to avoid ship-whale collisions. Intentional approach to Right Whales is prohibited and may result in a violation of federal or state laws.
