What do aluminum boat owners do to protect the hull against electrosis? It seems to me you would need an active system. Tossing on a Zinc is not good enough. AL is pretty close to Zn on the chart. In fact AL would make a pretty good sacrficial anode on most boats.
The danger is your hull gets pitted and could cave in on the next wave. I know larger ferries are aluminum but I bet they have an active supressive system. I can't imagine all those lund owners have something like that.
One other thing...does an AL boats sound like a garbage can being banged around when it hits the waves? It seem to me there would be an acoustic issue.
