The only spot that might be electrically weak would be the connection to
the mast out the top, but even that is unlikely. The galvanizing and
tight fit where the legs telescope into the section above should not
present a problem. IIRC the mast is held in place with two 3/8" bolts
which can rust. I have a flat plate top of both my 25G and 45G with
thrust bearings. so I'm not really concerned even though I do run a half
sloper for 160 on the 45G.
