The mix you describe will never cure out to full strength. This is not like ployester, where the MEKP proportion governs only the speed of the reaction, not the final cure. With epoxy, full cure requires a stoichiometric ratio of resin and hardener. One epoxide equivalent weight of resin requires one epoxide equivalent weight of hardener. The different weights of the components requires careful formulation and jockeying of diluents to yield easy ratios, but those ratios are critical. If there is more resin than there should be, the result is weak and flexible. If there is more hardener than there should be, the result is weak and brittle. The operative word in either case is weak, and the margin for error is only +/- 5% or so with most epoxies. You can heat that stuff for a solid year, and it will still be soft enough that you can indent it with a fingernail. The boats are so little, and the water is so big - do you really want to bet your life on a known defective condition?
The proper fix is to remove the glass and epoxy. With a heat gun and a putty knife with the sharp edges ground off, it will take about an hour. Been there, done that, have the pix if you're interested. Then sand lightly to even out the color of the wood, and do it again with the right mix. If you don't sand, splotches will surely result where the previous mix penetrated more deeply in some areas than others. At this point it's only a little extra work to make it right. Resist the temptation to play with it and make it right, because it can't be done.
