Stop paying the Ship Builder to repair your ship and repair it yourself for free!
I continue to see MANY players heading in to dock with low hull and sails on their ships, only to see them head straight to the ship builder and PAY for the repairs. (They don't need to do this!)
All you need is the ship builder skill and follow the below instructions while off shore at high seas.
1.) Cast Anchor
2.) Click the repair command (If you haven't copied it to your hotbars, do so now by dragging and dropping from the command window.)
3.) After clicking repair simply click on the picture of your ship in the ship window.
You will begin to repair at a rate equal to your ship building skill level.
Level 31 repairs 31 points per second.
