Very nice.

What material are your tanks?


Taiwanese "black" iron. This material is a low grade sheet iron, with a
bad reputation for rusting thru. They are also constucted contrary to
good principles... for example, the fuel suction connection is a pipe
nipple welded into the bottom corner, and there are no inspection ports
(and I suspect no baffles). However our tanks are in good shape because
the fill connectors are not over them, the way they are in most
trawlers, so the condensation & deck leaks don't pool on the top of the
tank (the usual spot for rust thru).

If we do have to replace them, I'm planning on sawing off sections of
the tops and putting in a foam rubber blanket to act as padding for
bladder type tanks. These are much better, no slosh, no air surface, no
condesation.

But first, I am definitely putting in a polishing system, with a pump &
manifold that will double as a transfer & stripping system.
