Like you Sailhack my hart was pumping. Were you in the bay or ocean
I could see him coming down the beach about 200m away, behind the break. At first I though it was a giant dolphin with side affects from the desal plant. He dove , I caught a wave. When I came back out he was heading across my path. I slowed down and our paths crossed. He dove, a bit of a relief for me, just as we met and all I could see were bubles and a bluish/white colour swiming down. Didnt seem him surface again.
If the ranger is reading this he/she swam under my board, I didnt sail over the top of him.
