Did a couple whale watching trips decades ago out of Provincetown, Massachusetts.
The whales toyed with the boat. Brushing and bumping under it unseen and then surfacing along the sides, seemingly, nudging it along, kind of directing the boat. They made the boat seem smaller than it was. They splashed us with their fins and tails, spun up out of the water twisting and making huge splashes, some easily rocking the boat. There were near two dozen whales.
Whales are huge, powerful, scary. Never go bird watching on a boat in whale territory.
