Besides the weight of sailcloth affecting the strength of the sail, the weight can also affect the sailing qualities of the boat. A boat using lighter sails heels less than a boat with heavier sails. A sail develops more effective force when it is straight up and down - not heeled over. The weight of sails, especially on large boats- can be significant. Masts are made as light as possible for the same reason.
