I have a 14ft aluminum v hull. I put temporary decking in this summer knowing I would take it all out and re frame work aluminum and use a higher grade ply with a non slip paint. Anyways..... I'm in Omaha, and it is now cold...... Like 3 months below freezing cold. I plan to remove all the old decking and do most of the framing and rough cut decking over the winter, then individually sand and paint then in the basement. Should I worry about expansion and contraction due to temperature change? Or is it minimal?
