I'm interested in people's
experience in regards to galvanic
corrosion on aluminium
boats. I really like aluminium
boats, however the
corrosion issue is really concerning. I'd also like feedback on a possible solution I am considering.
Assume a 40 foot aluminium cat.
Boat is often stored in a marina alongside other boats, possibly
steel ones. I would be many miles away.
Epoxy painted
bilge to prevent corrosion issues there and regularly inspected.
Isolation transformer to prevent issues from
shore power in
marinas.
Correctly engineered zinc anodes on the
boat.
A corrosion
sensor to
monitor the zinc anodes. This
sensor connected to a
remote monitoring system which emails me status of the corrosion, as well as other system variables in the boat.
Assume there is no issues with
internet coverage for the corrosion
monitor, and the corrosion monitor is reliable with a twin system for backup.
What do people think? Is it possible to design an anti corrosion system which is reliable?
I don't want an active catholic protection system as a system fault could cause it to drive a voltage differential and cause problems in a very short time. I would rather monitor the system using a dual redundant system.
Am I crazy?
