    help needed and advice,
    I have a alaska 500 and I amid fixing a new transom,I was lucky enough to be given a nice piece of 25mm marine ply,the only problem is that it is after I take out the longest piece it it’s an inch short either side of the boat,what would be the best thing to do?
    1, to stitch on the inch of ply I have left and fibreglass the 3 pieces together and then glass the hole piece
    2 or could I put the piece I have cut out and fill the gap either side with a resin and filler mix?
    Thanks in advance.

    Welcome to the forum.

    Pictures would help.
    One inch could be filled either way. Filling with plywood is usually cheaper than filling with thickened goo.

    The next guy will have a difficult time removing the hardened goo.

    Good luck

    Hi blueknarr
    Am new to this so am trying to get as much advice as possible, I did just put a new floor in with thermex which is a new honeycomb like selertex,am in the uk and have been told to get a new piece of plywood but that’s another 150$.but I think an inch added either side to the hull and well glassed in with woven rovin and epoxy resin should be just as strong? My ply is 25mm which will be glassed and sealed inside and another 25mm for the outside and also have a 316 plate to go on,what do you think,I will hope to show some photos tomorrow

    Some claim that little to no stiffness comes directly from core. I don't understand how plywood won't contribute significantly to stiffness. An eighth to one splice will provide same structural strength an virgin plywood. In your case; un-spliced will suffice. Add an extra layer and width to tabbing for extra peace of mind.
