    Default Advice needed

    I have an old plywood boat in my shed that a neighbour down the road wants fixed. It is of great sentimental value so when I quoted a large number hoping he would decline, he still said go ahead. Fool me should have quoted more. One problem is it has been left out in the weather by a "friend" and the plywood on the decking has delaminated. The other problem is it leaks. Replacing the decking looks to be reasonably straight forward, but the leak is problematic. Now I have the boatI have had a close look and there is a small gap between the keel and the first plank. Originally I thought we would slide the boat off the trailer and flip it and put a bit of epoxy in the gap, but then I noticed the trailer does not have a winch, so getting it back on the trailer would be nightmare, it is not a small boat. So forget that idea. The real problem however is after crawling around underneath I found a lot of tar goop where it has been leaking, and the owner confirmed he was responsible. As far as I know nothing sticks to tar except more tar, and tar doesnít stick to wood terribly well either, so the original plan is kaput. The tar never fixed the leak, so more tar is not likely to fix it either. The tar is now dried out and flaking off. How to fix this I donít know. Removing all the tar would be virtually impossible. Any suggestions? Is it fixable?

    I think the boat is fixable, so the real question becomes -- how much out of pocket will you be after fixing it?

    Fixing the gap between the first bottom plank (2 off?) and the keel should be relatively straight forward -- but you will have to flip the boat first. Not easy, I know.
    What I suggest is that you flip the boat and cut out the tar using a power saw. And only then decide if you will use epoxy chalking or wood to fill the resulting gap.

    The owner is paying for all materials and I quoted a large amountfor labour, so I should not be out of pocket. It is just going to take a lot of time, hence the large amount. This all started when a neighbour saw meworking on my boat and he referred this fellow onto me. He was desperate to get someone local whocould do the job, nobody else has the skills nor the tools. I am not an expert at boat repairs, but Ihave done a major restoration on my boat and have been a wood worker since Iwas 13. This boat is 30 years older thanmine, so is quite different (i.e. a lot worse condition).

    What you say makes a lot of sense so I have been crawlingaround and examining it again more carefully with a bright light to see if itis feasible. Looks like the first plankfits into a groove in the keel, so is not as easy as you say. Although it is made from plywood, the boat isclinker built with ribs and rivets. I did find another problem that I think may bewhere the worst leak is. There is a gapbetween the first and second plank about Ĺ m long. Unfortunately there is some tar in there aswell. The rest of the hull looks to bein quite good condition, unlike the deck. It looks to me like there is some sort of sealant between the planks andthat has been painted over, and the leaks are where the sealant has comeout. What it is I have no idea.

    I seriously donít want to flip this boat. My boat was easy. I have a tipping trailer and a winch. It took 2 of us to flip, but I flipped itback and got it back on the trailer by myself. This boatís trailer is not a tipping trailer, there is no winch, and itis quite a bit bigger and heavier. Theback of the trailer is also a fair way off the ground. I thought about removing my winch and usingthat, but there is nowhere to attach the winch to on the other trailer. Not only that, but there is a prop shaft(engine has been removed and is being repaired) that will get in the way and I reallydonít want to remove it. Risk of damageis high with the prop shaft installed, so it is staying on the trailer for now.

    I have started on the decking and it looks like a real ďfunĒjob, more or less as expected. Corrosion everywhere. The deck is nailed down withwhat looks like galvanised nails. The original nails are so corroded they come out easily, but there are a few more recent nails and screws, also galvanised and corroded, that are stubborn. The owner was warned that although the deckdidnít look too flash, what was underneath might be worse.

    Thanks, quite a bit more ambitious than what I am doing, but doing something very very silly is what I have been thinking all along.

    A bit more progress today. More decking removed and found a magnet to test the nails and screws. Some are magnetic, some not, so is a bit of a mixed bag. Whatever, all will need to be replaced. Found some rot so will need to remove some plywood I was not intending to touch, but no big deal (yet). Fingers crossed it has not spread beyond the plywood, looks like it has not, but won't know until I get some very rusty screws out. So far no rot on any structural timber, all good although covered in filth.

    "very rusty screws" implies either zinc plating or plain metal rather than galvanised.
    sounds very much as though you're the 3rd or 4th restorer.

    Leo Sampson's restoration is rather ambitious -- but when finished it'll be a great boat.
