Shrink Wrapping is a
Killer for any boat you want to keep "healthy". In spite of the "Vents" offered (At extra cost each..) to ventilate the boat.
The problem is the boat doesn't breathe. It's like a greenhouse. It warms up in the daytime when winter sunlight is available. At night the atmosphere inside.. cools down and condensation forms on every surface in the boat. Repeat cycle every day... ALL winter. It's your boat..
Canvas is a much better alternative... and it breathes. BTW: Canvas can be used over and over every year. Shrink Wrap is ONE Time only. Price it. Just sayin...
