    If I was sure it was not structural (and looking at it, I would think it is not structural) I would use a flexible sealant such as Sikaflex 291i on both sides and just use it for a year.

    As it is a new boat to the owner, he *probably* had a survey, so I would notify the surveyor of the claim on the surveyors insurance and then just get on an sail it for the year. By the next season, if it hadn't leaked I would probably have stopped worrying about it.

    How the heck would I get at #5? (Engine out, cut hole in cockpit deck?, or what?)
    On my first 2 boats the keel bolts were studs fitted into plain holes. At the bottom of the hole in the keel was a pocket. In this pocket was a nut on the stud. The pocket was then filled in with filler.
    I am not sure if a spanner could be fitted to the nut, due to lack of space, because it was probably tightened from above. However, you could be lucky & find similar pockets. If so you could shear the nut with a chisel, or perhaps even loosen it from there. Then if the keel slid down the stud you might just get it off.
    It is probably set in linseed putty & lead paint but you might be lucky if the weight of the keel worked in your favour.
    It is all down to the fact that my wife does not understand me !!

    #11, he didn't have a survey done.

    Something like this may also work. https://www.cromwell.co.uk/shop/hand...orque%20wrench
    Thinking about the hopefully never-to-be-needed task I reckon the only way would be removal of the engine and hope that a long socket tool could be manipulated through the engine compartment and down to the stud-top nut; which I'll bet is well and truly seized
    The nut is over an arm's length down into the bilge
    That clever "sideways" tool looks useful, but the length of square-ended rod needed to twist the nut would need to be extremely rigid, given the length involved. And that's if the tool could be artfully positioned over the nut

    Are you suggesting there's a nut at the bottom of the stud, and access would need to be by hacking through the keel to get at it?
    I'm not sure I've understood your suggestion.

    Thanks to you both, all advice gratefully accepted.

    .
    Basically - yes!!There was a purpose made pocket in the side of the keel which was later filled with filler.
    I have seen this on other keels as well
    If you think about it, it avoids having to drill & tap the cast iron to thread the stud into a hole which could be awkward and time consuming.
    A hole is made in the casting process & the stud just dropped down & a nut put on the bottom in the cast pocket.

    That's interesting, and I didn't know it - I wonder how many others don't know it too?
    Locating the pocket may be a problem. Sadly there isn't a Javelin30 Owners Association and the builder, Marcon, does not exist any more.
    From memory and photographs, there is nothing obvious on the outside of the keel which might indicate where it might be.

    I'll have a word with my usual surveyor, he might be able to help.

    Thanks again.

    There is not a pocket on my current boat, but owners of older boats might see the thread & it may be of use to them.
    Good luck with yours.

    to the OP- I assume that boat sits on the keel. You could ask the yard to lift the boat and see if there is a void between hull and keel when the keel is hanging free. That should tell much about the size of the damage.
    Do it yourself and do it good!
