If you epoxy the entire hull first with a thin coat- rollered on if possible, let it cure properly for a couple of days at room temperature, sand it down to a smooth finish, but don't worry about it being perfect.
Wet out the back of your pre-cut veneer peices with the epoxy and stick them on with a firm but not excessive clamping force, use a credit card or similar to scrape off the excess and again let cure for a couple of days.
Any gaps around the edges use a thick epoxy to fill- though the more accurate you are with your edge cutting you shouldn't need much- and let it cure, all the work you do doesn't take long, just waiting for the glue to dry takes day!!!.
Finally, one coat of thin epoxy rollered onto the veneer to seal it, let it cure, sand down to a baby's behind finish and varnish, Robert's your uncle etc!
Your hull should look really nice if you take your time, look forward to seeing it finished and varnished!
