If you haven't already... also might consider removing the winch

powder filler if you're going to thread the bolts into the epoxy
Refer to the Gougeon site for details.
This is a really good idea. I do this with all the fasteners on my epoxy ply trimaran
. I do this in a couple of ways depending on circumstances. For through bolting drill an oversize hole, take a Qtip and dab in a coat of straight epoxy then tape the back of the hole and fill with thickened epoxy. When dry drill appropriate size hole for fasteners. For screw fastening I actually use course thread machine screws/bolts and drill a hole again oversize and also a bit deeper than the fastener. Now the next step I have done two different ways. You can tap threads into the cured epoxy with a tap and die set. The other way is to set the bolt into the wet epoxy to cast in your threads. Spray the fastener with a release agent. I use WD 40 and wrap them in a tissue to soak up any extra so they go in dry. Stick the fastener in the wet epoxy and when it cures it should back out. Now when you put it all together use a washer or piece of hardware
and the hole should be a bit deeper than the fastener. You may want the epoxy a more a syrup texture as opposed to putty for this method.
Spruce, fir, pine, and cedar would be common wood
for masts and I would think for a small repair
any would work
