How does wetting down canvas sails increase the speed of a sailing ship?
When a sailing ship's canvas sails are wetted down, the water adds weight to the sails, which causes them to hang lower. This lower hanging position creates a larger angle between the sail and the wind, which increases the force of the wind on the sail. This increased force propels the ship forward at a faster speed.
In addition to adding weight, wetting down the sails also reduces the amount of friction between the sails and the wind. This is because the water acts as a lubricant, allowing the sails to move more freely through the air. The reduced friction allows the sails to catch more wind, which further increases the speed of the ship.
Overall, wetting down canvas sails increases the speed of a sailing ship by increasing the force of the wind on the sails and reducing the amount of friction between the sails and the wind.
