When we think about the form and function of a sailboat, it is a good idea to have a means of adjusting the sails. A simple machine, like a pulley, enables the sailor to raise and lower sails according to weather patterns. Being able to make adjustments to the sails can help the boat sail more efficiently and prevent drifting in the wrong direction. It would be quite the hassle to try to climb up the mast and make these adjustments oneself--not to mention the risk of falling! Utilizing a pulley means the sailor can control the sails from the safety of the deck with more efficiency than they might otherwise. Other simple machines, like screws, may be used to contribute to the structural stability of the sailboat.
