    Default Epoxy filler or resin for wooden sailing dinghy?

    I have a wooden sailing dinghy purchased recently, and after sailing yesterday I found some water in the buoyancy tanks. Rolled it over and found some small cracks on the edges of the hull. After cleaning out I think I have found the issue. Both sides have a small section where the wood is old. Photos attached. Question is should I fill it with resin and thickened with glue powder or use epoxy filler like epifil? I can't get to the inside as it is inside the side tanks/seat.
    It is a mirror dinghy. If I keep gouging it I fear I will create a bigger mess.

    I would use an epoxy resin like Boatcote or WEST thickened with the filler that they each sell to the consistency of putty.

    Grind the damage back to good wood and a feather edge, transitioning to the surrounding areas. This provides a place for the repair to live and smoothly feather into the neighboring planking. Wet out with neat epoxy (BoteCoat), insuring all the areas, including inside the damage is wet. Next mix up some thickened epoxy or use a premix product like BoteCoat's Epoxy-E-Glue. Mash it into the deepest of the damaged areas and smooth off as best as you can. The last part of the repair is to prep for paint, which typically requires some fairing compound, primer/undercoater and some top coats.

    Tanks Jm. I think your right. Still wondering if I should use fibreglass tape over that along the seam. I thought stitch and glue designs just taped the inside seams but have read about others taping exterior seams as well?

    Taped seam builds typically apply fabric over both sides of the seams, to control the plywood. If it's on one side only, the joint can "hinge" under load and crack.
