Titania: visited by a whale.

A whale swam by Titania around 5 times. Starting 300 metres behind then effortlessly swimming up to us and then diving down under the boat. It then repeated the same. It was hard to capture on camera - this was the best version we managed. 

I understand that it (or one similar) buzzed some other ARC boats.
