How do you properly protect a tin boat against electrolysis? And, what should one be looking for, specifically? |
If the boat spends it's time in the water, you need to pay special attention to electrolysis around the transom from the bottom up to the water line.
Usually this is caused by a poor ground connection which allows some electric interaction with the salt water, which is a great conductor of
electricity, and the aluminum is given up and the minerals of the sea water become attached instead. Normally this happens with aluminum boats but is
taken care of by sacrificial pieces which is normally the trim tab (above the propeller) and the sacrificial anode which normally attaches to the
motor right below the lifting mechanism.
I normally change those out about every three or four years, but if you trailer the boat and do not keep it in the water, this process can take a
much longer time to occur.
I live down here and fish probably 250+ days a year, so I use a boat a lot and because I keep up with checking the sacrificals I have never had a
problem with the last 3 boats I had (two Klamaths and one Quintrex). But, I did see a boat that was poorly maintained and they had a problem after a
year or so of staying almost full time in the water.
Aluminum is not the complete answer to boating and fishing in the salt, but it has proven itself to be a very good option. These boats are light,
need less horsepower to push them around, do not degrade due to sun, and are relatively easy to maintain and own. The downside is the minor quirks
of downwave handling (the Bayrunner being the most noticeable here), their tendency to slap the oncoming waves, and the tendency to oilcan and develop
cracks after years of hard usage but with the high price of fuel, I gladly adjust to the nuances of the material in comparison to a heavy fiberglass
boat with it's different set of operational challenges. |
