Coral heads called in the afternoon. These tiny underwater islands in the sea are extraordinary miniature aquariums and seem to house just ones and twos of a wide variety of species. Presumably there is traffic between these islands, otherwise there must be divine intervention to keep them populated. The coral head I snorkelled on had the usual suspects – parrot fish, sergeant majors, angel fish – plus the most perfect brain coral and a green moray eel nestling in the rocks.

After Jamie’s sojourn up the mast, the other kids were interested to find out what it was like.
