Red face Copper Liners in bilge and lazarettes

Any of you knowledgeable salts know why a boat would have large, thin sheets of copper laying as a liner in bilge compartments and lazarettes? new to the site and looking for our next boat! I believe I have this in the correct thread but please let me know if I don't!

Almost certainly to be for SSB/Ham radio installation.

Is it a wooden boat? If it is for a radio it would be one ground plane not multiples as far as I know.

So consensus is that it is associated with either an ssb/ham or a radio installation. Next time we look at the boat we will see whether there are any wires attached to it. THANKS for both of your replies.

No, it is not a wooden boat. We found the liners in three locations I believe. We will do a closer inspection next trip as the boat is on our short list at this point.

This copper strip pattern can be used as a substitute for a single ground plate. The tip-off will be wires connected at some point going to the radio system.

The only concern I would have with copper plates like that in the bilge is if the bilge is normally wet.. that would be a serious galvanic corrosion hazard for any other metal in the bilge. As others have said, it is likely a ground plane for an ssb or ham radio. However, there are ways of doing that which would not present a galvanic corrosion hazard.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

On our friend's Passport 40 he glassed it all in with epoxy and a layer of cloth.. so it's not really exposed to anything.
