I froze the image and estimated the whale was around 42 ft long, the same as the boat. The show the whales put on that day was a once in a lifetime scene. It went on all day and night and into the next day. Between 4 and 5 whales were feeding on salmon smolt probably released by the Hidden Falls hatchery at the head of Warm Springs Bay. They were going under the floatplane dock, the main dock, and boats tied to it. They would surface near the float plane dock close enough to touch their fins. While pouring a cup of coffee, the next morning I looked out the window to see a fluke a couple of feet from the rail. That whale was going for the smolt trying to hide under the boat by going by on its side. Never once touched the boat but rocked it a few times with “prop wash” off their tails.
