Get some of the System Three Clear Coat epoxy. It is much thinner, has a
longer cure time, and will get into the crack with capillary action. Also
heat up the daggerboart with an electric blanket before putting the epoxy to
the crack. Do it in the evening so that as the daggerboard cools it will
suck more epoxy into the crack. Very small holes drilled at the top and
bottom of the crack sound like a good idea also.

My 13' sailboat has a mahogany daggerboard. There is a crack in it,
running
about 1/3rd of the length, about 1" from the trailing edge.
It does not affect anything, but I am concerned it will crack further and
break off; so I am hoping to stabilize it to prevent that.

I showed it to a cabinet maker. He suggested routing some slots in it,
perpendicular to the crack, and filling the slots with fiberglass/epoxy.
The slots would have to be pretty small, because there simply isn't much
material to work with so close to the edge. I would then put a layer of
cloth over it to hold it together. (there ought to be enough clearance
for
a layer of cloth.)

I have some leftover glass cloth and epoxy from another project, but
wonder
about the technique. Would I take some cloth apart and soak the yarn in
epoxy, and then stuff it in the slots?

Any advice would be appreciated.
