Jumping jack ... humpback

Any guesses as to what I've been watching today?
Just a little boat trip. First off was some spinner dolphins for a quick swim (sorry no underwater pics) then off to look at one humpback doing tail lifts, followed by two complete showoffs, breaching multiple times over about half an hour period.
Pics are in the usual place - enjoy.
PS My last day in Hawaii - next stop San Francisco
