Ross, not many whales per se in the Chesapeake
but I remember being on an ocean beach on LI near Amagansett and seeing a few spouts of water and the telling black outline of a large Cetacean out in the Atlantic about 3 to 5 miles around late September once about 10 years back. The Atlantic whales migrate south in the winter as do the Pacific whales including the grays who summer off Alaska. I had a chance to meet some gray whales while visiting Hawai'i off the island Kauai in a fairly large catamaran in March of last year. They do their mating and calving around the Sandwich Islands and then head off for summer near Alaska. While on the tourist catamaran (around 45' with twin Cummins diesels, food and drink provided) one of the aft stays began to vibrate and hum this incredible fairly high pitched sound as we were witnessing some minor breaching of a small group of whales. To me, it almost sounded like the VHF radio was feeding back on itself (which it shouldn't) but the crew reassured me that that was a whale making noise, probably a bull screaming at another bull to leave his mate alone. I guess I will never know what the message was but it sure was incredible that the rigging of the boat picked up the vibration of the whales utterances below the hull. I was also told that if I could dive while snorkeling down to about 10' below the surface that I might be able to hear the whales calling.Edit to add: It is a little bit unnerving to think that you are on the water with a whale beneath your vessel that is both longer and stronger and probably more nimble in the water than the boat you are on. Since I have no clue as to where the gray whales are at on the west coast I leave this discussion only with the idea that I wish I could go with you guys; looking for the grays.
