I have to heat post cure the floats. A minimum temperature of 50° C for 16 hours is required to obtain maximum mechanical properties of the epoxy. I have a 40 kW heater delivering a significant amount of air, a 5m x 7m quite heavy canvas? (presenning). The temperatures in Levanger at the moment is between 0°C and 10°C, so that is what I have to fight... Any ideas on how to do this is appreciated.
I figure I will line up the floats parallel, cover them using some sort of frame to make a "tent", 7 m long and as narrow as possible. Then let the heater blow through this tent. I might have to reverse the floats in order to achieve the required temperature in both ends. I am really trying to figure out the best way to do this.

Hi Tor,
Inside my working space, I will try to build with the remaining Foams plates (for the mainhull)and and some wooden strips a kind of isolated heat tunel. On the exterior side, I will cover the foams with plastic sheets. Thus I hope the baking oven is enough thermally isolated.
Instead of to turning the floats around, i would bring the air intake from one end to the other end.
Thank you, Roger!
I will implement the idea of using the foam for insulation!
