The foresail was lowered and the mainsail partly brailed up, so that she had only way on her sufficient to stem the tide. As they entered the broken water Jack was obliged to take a step back and hold on to the mast. Her motion had before been violent, but to a certain extent regular; now she was tossed in all directions so sharply and violently that he expected every moment that the mast would go. Tom looked round at Ben. The latter pointed to the sail and waved his hand. Tom understood him, and going to the mast loosened the brail a little to give her more sail, for the waves completely knocked the way out of her. When she forged ahead again, Tom returned to his post.
