With the mast in, I found a 10' x 12' white heavy duty 12mil tarp fits
best to keep rain and snow away from the cabintop windows, the
handrails, and genoa tracks. It doesn't shed snow like a boom tent but
it is much more sturdy and reliable and does a great job redirecting the
rain and snow melt. I place some cushions underneath to reduce the
amount of puddling.
