I am unfamiliar with that boat, what wood is being used, and what do you want from the finish?
Epoxy laminating or finishing resin is what you need to use, west systems is a popular brand but they all do the same thing with minor differences between brands, so just buy whatever brand is available in your area.
As above epoxy can be thinned with IPA, and heat will also thin epoxy, if you want the best penetration stand both parts in a bowl of hot water before mixing. When thinned it soaks into the wood better for a more ding proof finish, or unthinned it can be mixed with glass microballoons to a thicker paste so it doesn't soak in for a less ding proof but lighter finish. The bond lines in ply will stop halt the absorption of epoxy so only the outer ply will be soaked, but thin resin will soak right through balsa and give it a lot of extra strength but at the cost of a lot of extra weight. Heat shortens the cure time of epoxy, and over thinning with IPA can result in microbubbles formed when it evaporates and porosity.
For the ultimate in ding proof finishes, apply a coat of thinned resin, let fully cure, sand, laminate a layer of 25gsm glass cloth on wit unthinned resin, let cure till tackyness stops, apply another layer of resin, let fully cure, and sand most of the last layer back off.
