... If you're worried about galvanic corrosion, use the
same material as the hull, put down a grid of half-round. To
prevent pockets & puddles, you could fair it over flat with
some cladding.

Fairing componds suck on steel or any metail IMO. They hold moisture

True. But then, nothing's perfect (except carbon fiber, of
course).


The issue is not galvanic corrision, but trapped moisture.


That suggestion above was an idea of how best to reduce both.


One of the best features in the Oragami boats and the Strong All yachts
is the lack of framing. Framing is metals boats worst maintance
problem.


Yep. Some of the Navy ships I worked on had frames that were
rusted all the way thru, right at the junction with the
hull... most noticable hull rust there, too.


yelp..it's due to improper construction and maintaince.

Oh yeah, I'll be sure to tell the Navy exactly that, next
time I see them.




... Any place
moisture can set on steel or be trapped is bad...

Agreed

You mean, like on a boat




Yep... only problem is if you bang something against it, or
if it gets fouled up with barnacles etc etc.


Next to the keel they are protected. Inspected boats are in the yard
enough to deal with fouling.


Good point, but it doesn't come cheap. Also doesn't equal
1/10th the man hours deployed on steel hull maintenance by
the Navy.
