Plan view of sheeting arrangment for jib. The block on a string can be adjusted by selecting the appropriate hole. Sheet runs from sail, through block, is turned 90 degrees through ratchet block, through cam cleat to crew. Same arrangement, different view. Note also, diaphragm pump mounted on the knee supporting the forward end of the bench.
Pumps are necessary for coping with the odd wave.
The self bailers will cope off the wind but if you find yourself having to go to windward in a turbulent sea you may well need to pump water out. If you are unlucky enough to capsize, the best pump, as they say, is a frightened man and a bucket. An anchor line reel is also visible just forward of mast step. An unreliable anchor is worse than useless. My personal opinion is that grapnels are unreliable.
