Joe Fig says legit, so I dove back in for another look.... And the hole is not as bad as I first surmised, though it is in a sturdy section of the hull. Once you take away all the bags, towels cushions, and whatever else the crew jammed into the hole to prevent water from coming in, it looks like it could have been made by the whale's fluke. I think we have all seen footage of whales slapping the water with their flukes. Just never thought of being within their reach....
