According to the experts at Tom-N-Jerrys Boats, aluminum boats are highly versatile and easy to maneuver. They are a great option for the novice boater or the more advanced offshore angler. When you use an aluminum boat in saltwater, there are certain things that must be done to protect the hull of the boat from corrosion. By following these steps, your new or used aluminum boat will have a long and healthy life.
The presence of saltwater alone does not cause what is known as galvanic corrosion. However, when aluminum, saltwater, and another metal come into contact with each other, the corrosion can occur. The saltwater acts as a conduit for the other metal to strip away atoms from the aluminum of your boat. As the atoms are removed, the aluminum becomes weak. Over time this can be a big problem, especially since no one wishes to have holes in their boat.
One of the easiest ways to protect your aluminum boat from galvanic corrosion is to keep the bottom and outside surfaces painted with a protective coating that creates an electrically resistant barrier. On a positive note, each hour that your aluminum boat spends dry docked, adds natural protection to the surface. As oxygen in the atmosphere come in contact with the aluminum, the surface develops a dense film of aluminum oxide. This heavy and naturally occurring coating, bonds to the hull of your boat very tightly. The staff at Tom-N-Jerrys Boat Center explains to buyers that aluminum oxide helps protect your aluminum boat.
