Rarely when whale watching do you get a chance to relate the size of the whales to anything known. For the most part, they surface in the middle of a large tract of water where there is nothing to put their size into perspective. Even when they approach a whale watch vessel, it's hard to comprehend their size. This humpback, Pinball, went on a deep dive right next to a pleasure boat. I would like to add that this particular boater was practicing safe whale watching, engines were off and he didn't move the boat until the whale re-surfaced at a safe distance. This photo shows just how big a humpback is, and this is just the tail!!
