What is a carpenter and how do they work?
Carpenters can repair the hull of your ship. You have to do this manually, and it can be done once per tick. A ship can be repaired only by 1 carpenter at a time, and the carpenter must have been at the ship at the beginning of the tick. How much he can repair depends on his skill, according to the formula: 15*skill-300, with a minimum of 200 points.
