    Hi All,

    I'm currently trying to save my old boat which has been neglected for a number of years whilst I got married, had kids mortgage etc! Ive attached a pic in better times and her current state.

    She has a teak on oak hull and steel superstructure

    One of the jobs I'm looking into now is a rotten steel forward collision bulkhead. Im repairing/replacing the oak frame it is bedded to and was thinking of replacing the bulkhead itself in 316L SS.

    I've other work to do as well, there is internal carbon stiffeners around the transom, the rotten carbon floor carriers are gone and need replacing etc which I could also make out of 316l.

    My thinking in using is long term maintenance reduction. Can anyone see a reason why I should not replace some of the carbon steel elements of this boat with SS, from a galvanic point of view or otherwise?

    Thanks in advance

    there are a number of kevlar reinforced epoxies and mcu coatings that might save the day and provide a long term fix

    Thank you,

    I think I may just rip it out and repair it. It lasted 90 years as is so maybe SS would be overkill and work creation. If I fix it up what would be your preferred paint system. I see some use epoxy as a primer and then paint. Is this correct and would this be the correct procedure if I was to soda blast the superstructure?

    As your steel will most likely be hot rolled, ensure to blast to remove the mill scale before painting
