Here's the article I used for mine.
Just using the 6mil plastic, they say it made a 5-10* difference. With any kind of heat it should be much higher.
I don't plan on building in mine, but with those lights on inside, you can certainly feel the heat.
No Greenhouse affect with these blue tarps or at least very little sun will penetrate.

This building ( mine ) is about 7' tall and 10' wide. Lots of room to work.
You could certainly build a smaller hanging tarp over the boat and the two tarps and space between would help to insulate.

I used 1" x 3" fir strips and ran screws through with plastic in between to hold the sides down, but also buried the wood in dirt, inside and out.

I hope that you are able to use it effectively.
