Hull Anodes

Corrosion to your ship can be prevented. For this, you strangely enough need a component that ensures that this natural chemical degradation does take place, but in the right place: the anode. This is a metal component placed against another metal surface, preferably one that is susceptible to corrosion. Thanks to the placement of this component, it will protect this surface from attack, while slowly crumbling itself. So an anode eventually has to be replaced.
