tube carrier drains, (scorpion)
As part of my boats refurb. I had the pleasure to cut the old tubes off this weekend.
My friendly tuber cautioned me about Scorpions suffering from Osmosis in the aft tube carrier sections. I really shouldnt have been surprised to find a small pond behind the port tube, including a slug.
I am lucky as my boat is a vinylester layup and no osmosis, none the less I have overcoated in epoxy and filed imperfections.
While roughing it up I found a small circle indent, out of curiosity I ground it out, and found it was a hole into the outer part of the hull. There is alos one forward, which I havent ground out yet. My previous Scorpion used to leak water from port tube when I pumped up the aft tubes too. Its obviously a common issue.
Question is, do other boats have tube carrier drains, into hull? Can anyone think of a problem with having them?
