We see whales just about every time we cross MA bay, going from the Cape Cod Canal
up to Tennant's Harbor, or back. 30 minutes of breaching last time, about a half mile away. Just off the beach going in to P-town we had one surface about 30' off our starboard bow, apparently feeding on the baitfish that were jumping all over the place. Look up the names of the whale-watching boats on their websites and AIS
is your friend. They also talk with each other over the radio
to locate pods. Don't know what channel. Maybe 8 or 13?
