I recently bought a '74 Catalina
25. When I bought it I noticed there was a plate or patch on the port side about midway of the boat
underneath what looks like about 2 foot below the water
line. The previous owner told me he thought the plate was an old patch that someone (not him) had put on to stop the thru hull
on that side from leaking. Upon further examination tonight to see what it was going to take to get the head
working, I noticed a heavy gauge wire (size 4 maybe?) leading from what looked like a grounding lug on the port side, beside the waste tank, up to the mast
step. I have the boat
pretty well covered in heavy tarps and didnt uncover it to look but the wire went right up through the deck
where the mast
sits. Anyhow, when I was looking at the thru hull
I noticed that it wasnt capped off. I went outside and looked at the "patch" and it wasnt even really near the thru hull
, in fact it was closer to where the ground lug I saw inside was. Is this normal to have this on this boat? Should I just eventually remove it? From the outside it looks like a plate thats about 6 inches wide and a foot long with what looks like a carraige bolt through it in the middle. The plate is coated in bottom paint
, which is new this year, so I probably wont mess with the outside plate this year.
I know lightening protecting is a very controversial subject so I am not asking if I should make sure its connected or not, I am more just wanting to know if its an add on from a previous owner or factory installed.
