Don't listen to some of these folks. Get marine epoxy.
Superglue works great.... for about a week until moisture creeps back into it. Your board is going to be exposed to ice and water, violently while you are jumping up and down on top of it while sliding down the side of a freakin mountain over rocks and trees.
Get the strongest, most robust stuff you can find. Better safe than stuck at a resort with a board you can't ride!
