Hey all,

I've registered on this forum a couple of years ago (2012), as I had been offered a wooden canoe from a friend, who let it to fall into decay...
So, I've started to read articles and watch videos on the internet, about renovation and I realized that, in addition of being something possible, it also looked to be technically reachable in my case...

That's why I'm here, just to evaluate with your help, the magnitude of the work needed, and the level of skills required for it. I'm joining here (https://plus.google.com/photos/117442957405492535048/albums/5748637986935621121?authkey=CNz_orXclq3DVw) an album of the canoe. I've tried to put together pictures referring to the same part. I hope you will easily understand about how it is organized and where are the spotted parts.

For sure, you will notice that both bow and stern are seriously damaged. I'm so planning to take off all the mastic (you know, filler), strip the wood, lightly sandpaper and then varnish it back.

However, there is a mastic applied between each strips. So, do you think it is necessary to unscrew all those strips on the side and bottom, take off the mastic, restore them separately and screw them again (isn't there a risk that they change of form?) or a waterproofness test (like putting some water in the canoe and see where there are holes) and detecting gaps between strips when the mastic is all dried is enough?
Also, the inside of the canoe looks in quite good condition, don't you think? I haven't seen any draught proofing with mastic in the inside...

I hope I've been clear (you will notice that my skills in english are limited, even more when it's to talk about canoe...) and that you disapprove the posting of a new thread for my project.

Thanks in advance for your precious help.
Till next, Bapt.

Looks to be in excellent condition inside , and seems to have been stored well and dry.

I would repair the damaged parts as you said , then try the boat out ( float test ) .....It looks like a really nice old craft , and I would change / strip / repair as little of the original boat as possible. I would accept one or two slow leaks as part of owning such a boat , good luck !

I would agree, and ... Nice little boat!

Hello,
Boat fan, here's the link > album (https://plus.google.com/photos/117442957405492535048/albums/5748637986935621121?authkey=CNz_orXclq3DVw) :)
Thank you for being that reactive, I'll try to fix the most damaged part (on each side especially) and take it to the river. However, what to think about this old mastic which has turned into a yellow color? As far as it makes its job and keeps the boat hermetic, can I just just leave the seals as they are?
Again, thanks for the help.
Bapt.

Hi , tiobas ,

Thank you I missed the live link in your original post ...good pictures.

Personally , I would not worry too much about the sealant , it is quite common for some to yellow or discolor with age , and who knows what was originally used ?

You have identified the needed urgent repairs , why not do those first , and then I would just try out the boat , and review any further ( if any ) actions that may need to be taken.

My approach would be to leave as much original as is possible.Minor leakage can just be sponged dry after each use ?

Hey all,

Sorry for being that long to respond. I've actually gone back from Nepal a few days ago and have to write a huge internship report for my school.
Boat fan, thank you very much for the feedback as well. I couldn't expect better optimism from you guys and I'm planing to spend the whole day to work on it tomorrow.
Still have a few interrogations remaining:
> You can see on the two last pictures of the album (here (https://plus.google.com/photos/117442957405492535048/albums/5748637986935621121?authkey=CNz_orXclq3DVw)) called stern and stern2 that, despite the big layer of sealant, there have been cracks appearing. Should I try to take it off with a spatula to make a proper seal?
> Also, I was thinking of sanding the outside part to give him a new layer of varnish for UV and seawater protections, what do you think of doing that before the floating test?
> Any idea about the variety of wood it might be made from?

Thank you, have a nice WE to you all.
Bapt.

Hi again tiobas .

That sealant may not be doing much to keep any water out ?

Personally , I would carefully remove as much of that filler as I could.

It`s hard to say from the photo how that planking is fastened to the stem , ( nailed on ? or screws ? ) but after removing that filler it would be best to somehow open that joint up and re - bed the joint and re - fasten it . You may need to get some new boat nails or bronze ring shanks to replace the old ones . Or may be bronze screws , whatever was used originally.

To do that you would need to carefully open that joint by wedging it open with small wedges tapped in from inside the hull to create a gap large enough to apply new sealant.

Thick paint could be used as a sealant , or a bedding compound such as Dolfinite : https://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0CCQQFjAB&url=https%3A%2F%2Fwww.pettitpaint.com%2Ffileshare% 2Fproduct_pds%2FDolfinite-Bedding-Compound.pdf&ei=QLGFVavkNsXBmwXo6YCQCQ&usg=AFQjCNGU0T1iTS39dQQzDhAFTk3aWGoyyQ&bvm=bv.96339352,d.dGY

The most important part of that repair is surface preparation , it needs to be clean , nothing lose or flaking inside the joint , no dirt etc .....

If you do this , work carefully , take your time , and keep all as intact as you can causing as little damage as you can.

Good luck , it`s a nice old boat.
