Dont get attached to that hull.
My first scratch built was a scale 1920's cigar racer that was too this day one of my best ever, unfortunately, while glassing I added too little hardener and suffered the same fate as you...."xxxxx"!
In the end I used talcum powder to remove the tackyness and reglassed it, but the beautiful woodgrain I had slaved over was stuffed and that model felt the heel of my shoe in a fit of rage.....sigh...25 years on and I still regret that temper tantrum.
So to sum up, you may be lucky and save it, but if its tacky after 1 week I wouldnt give much for your chances of bonding the next layer cleanly.
And yes, EPOXY is a-poxy mix!
cheers,

P.s try a hairdryer. Altho epoxy is a chemical set, it is prone to stay tacky if the humidity is too high (65%) or the temp below 20c, and in those circumstances a hairdryer, a 6 pack and a couple idle hours may just save it (at least the beers salve the pain).
