Well, I would do the following -
-since your stand up paddle board is not that big, I would hang a tarp over it, and stick a blowing-type-electric-heater underneath. I am quite sure that would raise the temperature a bit. Blowing type - to distribute heat more evenly.
-if tarp were unavailable, some poly from home improvement stores would work. Or those emergency mylar blankets, they might be better since they do reflect heat.
Think positive - since it is cool you have extra time to work with glues and epoxies.
That board looks very promising - are going to fill it with low density expanding foam and glass over?
