Default Seamanship Question #17 Galvanic Corrosion

[This question inspired by Capt Neal]

You just sold all your powdered Mercury, that you
made into a paste with tuna fat, and had enough
money left over to purchase a 56' aluminum yacht.

It is an expensive aluminum yacht, therefore cost
is not a factor in developing mulitple solutions to
protect the hull from galvanic corrosion.

What are your solutions? [1 pt]

No loose change on board.

Cheers

Do not use the hull as a ground return for any part of the electrical
system.

Keep the interior dry.

Wipe it down with the remaining tuna oil.

Since the boat is already produced, there
is little one can do other than install cathodic
protection. An active cathodic protection
system would be more effective than a
passive system such as zincs.

Active cathodic protection uses a little electricity
but I'm sure the battery bank would be large
enough on a 56 foot yacht to accommodate it.

Don't buy aluminum unless you have a Class D fire system and plan to spend
as lot of time on maintenance instead of sailing.
