The actress's burly sidekick was on hand with the soap as she hosed herself down after a dip in the water.

Clearly he takes his job very seriously.

Quite what he was expecting to encounter while at sea is anybody's guess. But as they lay side by side on the deck, there was little space for anyone to get in between them.

Laying out on a towel on the front deck of the vessel, Scarlett was the centre of attention in her white Bond-style two-piece.
