    Default What boat soup would you recommend here?



    cross refer Uffa Fox 14 thread in “Boat Related”.

    What you are seeing are 1/16” diagonal Honduras mahogany planks with a layer of cloth between them and the outer 1/8” fore and aft planks. The ribs are 1/4” x 3/32” Canadian Rock Elm.

    I was thinking clear Cuprinol and raw linseed oil?

    Sounds good to me. I did much the same with a commercial preservative made by Sovereign Chemicals. The linseed will take ages to dry though, creating more work when varnishing.
    It really is quite difficult to build an ugly wooden boat.

    Damn, that's a serious responsibility.

    I dislike linseed oil for anything outdoors

    Cpes.
    What will become of the boat?
    Will she be sailed or reside in a display?

    Sailed. We don’t have cpes here, but I don’t like the idea of anything that sets hard getting into the cloth layer.

    Can we assume that the cotton is rotten by now anyway?

    Is the cloth cotton calico or is it Irish aircraft linen? - and has it the traditional white lead paste?

    It’s whatever Fox used. I have noticed that his workmen were quite traditional in their approach to details. There’s no way to find out non-destructively! Certainly white lead paste has been used to bed fittings.

    Equal parts turps, boiled linseed and varnish. Let it dry to just tacky and then one coat of varnish thinned with turps enough to make it easy to splash on with an old brush.
    The varnish will keep the BLO from turning black.

    If the Cuprinol is white spirit based that will work with BLO and copal varnish.

    This is what I would do, assuming that you are going to varnish the interior.

    Yes. Some of her sisters have paint in the bilges, but they were not built that way and I would rather see “what is going on”. There is no way to keep a racing dinghy bone dry; you can mop her out with a chamois leather but if you keep the mast up rain will trickle down the mast luff groove.

    ACB, this sounds like a challenge to a bunch of woodworkers to whittle a LGDD (luff groove drip diverter)

    Nice work stripping and scraping the interior. What a tedious job that is, but it will shine like a new penny when done. Kudos. And it only took three years.

    I would use high grade varnish, lots of it.
    Edit: And I might be tempted to stain it first.

    There are fifteen coats of high grade varnish on the outside and a lot will be going inside too. But I want to use some sort of preservative

    Copal! - That's hard stuff to find these days - HAMMERL GMBH & CO do traditional varnishes but at eye watering prices

    https://palacechemicals.co.uk/shop/e...copal-varnish/ No idea about the price

    I had an uncle who was a highly respected luthier - and spent quite some time experimenting with varnish recipes - here's a similar example - complete with ingredient list.

    If you are going to varnish the inside, then I would just use the cuprinol. Keep putting coats on until it won't absorb any more then allow it to dry for at least a week before starting to varnish. Linseed oil won't add much more than stickiness.

    Thank you. I will fill the centreboard case with it as well.

    Why are you not just varnishing the inside?

    I shall be. But knowing how water accumulates in the bottom of racing dinghies, no matter how hard you try to keep them dry, and fearful that she may not always get the best care, I want to give her the best chance whilst I am able to do so.

    The bottom boards for instance are not removable but are screwed to the ribs. I’ve got them out at the moment but that’s the first time in her life.

    I used Barratine oil based rot killer as a basis for my boat soup for Kates decks.

    1 x Barratine : 1 x tung oil : 1 x boiled linseed oil : 1 x real turpentine :1 x 0.2 pine tar.

    Boiled linseed oil as opposed to raw for better penetration. A small amount of pine tar for decks.

    Larch deck planks, after 3 coats it stopped taking up. This photo was taken 3 weeks afterwards. Came out ok I reckon.

    The cloth is almost certainly gone. Finish cleaning up the inside with oxalic acid. Then varnish. The inside is all one can see so do a good job. ("boat soup" is usually just a bunch of nonsense.

    If kept in water and covered, it will be fine.

    Fundamenally you are really looking at a varnish primer. something that will adhere to the wood and not lift off. What does your varnish brand recommend? The linseed oil will not do you any good, and I am unfamiliar with the other concoctions.

    The cloth may well be deteriorated. The linseed oil is thin enough to run into any seams and gum up enough to help seal the hull. It's the only thing I have found that will seal 90% of any weeps and seeps. I have even heated the oil up until you can barely stick your finger in it. This will thin it even more, and help it run even further.

    If the cloth was originally bedded in paint of some kind, I can't imagine an epoxy sealer making much headway in there. If it wasn't, then yes, you'd be some future restorer's public enemy number one.

    How about Deks Olje No.1. Gives a good base for varnish.

    Has the boat ever suffered a lick of rot?
    Have you ever sat on a piece of freshly cuprinoled wood ?
    (nasty red toxic blisters on ones bum).
    Anyway, I might avoid poisoning the boat, I'm sure she will recieve the finest TLC in the future and not be "put away wet".

    She has lasted pretty well until now with just varnish.
