looking for a better way to fix a leak in a board well  Bottom

Go to page [-1] 1 - 2:

  • traphappyWhy not just do the repair, lube up the board, and put it in place? If lubed it should come out without issue.

    the hole is not on the wall where it would touch the board
    it is inside a recess just is inside the lip.

    look at the pic again : instead of looking at the arrow at the bottom of the well (where the leak is) look at the top of the well, on the left - it's the exact same shape

    i don't think a patch is the right call because the patch would be almost impossible to get in the exact right location and if it was hanging outside the recess at all - it will scratch up the board

    I am tempted to use 2 part pool epoxy - it stays flexible and can last for a very long time and is a 4 minute job (just mix it and smoosh it into the hole)

    But i know the right way is to flip, and add some vacuum

    thanks all!

  • MN3i doubt it - if i can put that patch there i could put glass

    the issue is really sanding it down afterwords

    What about the use of a rat tail file to sand it down? Round Rat Tail Diamond Needle Files 10-Inch Round Shape 180#

  • Or use a wielding rod with a Dremel barrel sander head on the end. Use the Dremal for power and reach down and sand it that way

  • HI Forrest - thanks for the input
    i have round files that are pretty similar to the rat tail ones you show -
    as per the dremel ... i am a little hesitant to put a power tool in there ... where i can't see - i am sure it could be done but i am sure i could screw that up too... the walls are really thin in spots and it would be tough to feather any sanding without enlarging the hole (i think)

    i am gonna try to sans power tools but thanks for the tip if i need to get some powersanding in there

  • Tip the boat on its side. Not too bad with a second person. Then you will likely be able to get in there with a hand and sandpaper. I could on the Infusion trunk, similar location, this is the Mk. 2 trunk that is very narrow. Scuff the trunk, wet out a piece of 6oz fiberglass, guide into place with sticks as necessary. Let cure and go sailing.

    I say all this because the centerboard doesn't contact that location per your description and 6oz cloth is 0.010" thick, so won't change the contact either. Brushing G/Flex in will likely work just as well, but you have more control with 6oz cloth in terms of wet out and you can let tack up before installation.

    I did the same thing but used a tube of UV cure epoxy in addition to the fiberglass: https://www.solarez.com/product/solarez-extreme-3-5-oz-tube/

    Amazon carries it as well. This was an on the beach repair in the Florida 300 and it held for the next 200 miles so...
  • This is how we fixed a similar leak in the side of P18-2 trunk. It was a bit easier because it was at the joint of the hull and trunk, so easier access. G-flex and cloth were easy to work with when boat was on its side.

    Andrew,

    Some dremels offer flex cables about 18-20" long This way the sander stays outside and you sand with the cable and just head. Think of a dentist. Check Walmart for them or hobby shop. I had to grind out the glue on carpet in my well to replace the padding Dusty, but works well.

    Good luck

  • Nope, that image shows the tool rigged correctly. It isn't that much smaller than a regular dremel.

    I recently saw a Ryobi tool that is very similar, as they made it compatible with their existing lithium drill batteries so had to go to a remote tool head.

    Honestly though I think you are overthinking the job...a piece of 80 grit sandpaper is enough to scuff for adhesion of a fiberglass patch.
