Default More rebuild and refit photos, grounding the mast?

Things are beginning to go back together rapidly. Bow thruster
scheduled to go in next week.
With any luck will be launching in two weekends.

There will be a new aluminum mast and boom installed. I suppose the
yard has this all figured out, but just in case,........

1) The painted aluminum mast will be stepped into a bronze fitting.
With dissimilar metals in contact there is a potential for
electrolysis. Being a stinkpotter and therefore relatively
inexperienced with masts, what precautions, if any, should one take?


Chuck:
I just did this. Took mast down, added winch (The dinghy gets heavier
every year), and repainted.

Same situation. I used discs of nylon between the parts and lots of
anti seize compound on the hinge pin.

Note the flooring. It's for trade show flooring, and play surfaces for
children. Wonderful stuff. Stays put, has non skid, uv resistant,
sound deadening, feels good under foot, and is very inexpensive ($1.38 a
sq. foot).

2) The old wooden mast wasn't much of a lightning hazard, but the new
mast would serve as an excellent conductor in the event of a lightning
strike. Ideas for grounding? Is it important to ground it?


Mine isn't grounded. Yet.
