Bert climbed cautiously out of the cockpit and made his way along the slippery deck until he reached the bowsprit. Clinging to the mainmast, he steadied himself while he surveyed the thrashing sail, whose folds of canvas hung over and trailed in the water until, caught every now and then by the wind, it bellied out like a balloon. A wave bigger than the rest completely submerged the bowsprit as the boat plunged into the trough of the sea.
