Sounds awesome, and even better it being a private show.
I wonder if they breach more in calving areas?
We're in a Humpback feeding area, so they breath about 7 times, deep dive, stay down for about seven minutes, come up to breath about 7 times, deep dive, repeat, all day long.
We saw one breaching in the distance in Princess Royal Channel, it kept breaching for 45 minutes while we hovered at a safe distance, and kept on breaching as we motored off. Must be fun
