A giant bubble ring right along side the boat. A glimpse of a fin, a smooth humped back then the unmistakable snout of a humpback whale. A group of three were cooperatively bubble net fishing. They coordinate an air bubble release under water to corral a school of fish then chow down. Just amazing.
Overall we saw probably 8 different whales (My tail fluke coloration pattern identification skills are not so great). We saw many great tail flips as they dove and even saw a mother and her calf.
We had a great trip with Whale Watch out of Provincetown Mass.
