I have corrosion problems in the interior of my steel-hulled/aluminum-hulled boat. Can Sunmatic correct this problem?
ANSWER 2: The interior galvanic circuit is independent of the exterior: a different electrolyte. For this reason the interior of the boat is not protected. Only if there was water in the interior and connected to another system could this area be protected. The best solution is to keep the area dry and well painted. In some boats where water in the bottom of the boat tends to accumulate, sacrificial anodes are sometimes used in those zones. QUESTION 3: I have stainless steel freshwater holding tanks in my boat that are isolated from the carbon steel hull but I have corrosion in the interior welds where there is water. Does the protection system for the exterior submerged parts prevent this? ANSWER 3: The protection system used for the submerged parts of the boat cannot prevent this. Connecting the tanks to the grounding point along with the rest of the metal parts can lessen the corrosion. It is a mistake to isolate the tanks from the rest of the metal. Additionally, titanium anodes wo
