. Boat tarps? Then there's the skill of whoever put it on, whether they got it fitted and snugged down, or left it a little loose vibrating in the wind
. It isn't all quit the same and that's one argument in favor of custom boat covers instead of tarps.
Depending on local custom, boats that are hauled in the winter may be kept mast-in or -down. Something else to consider is that if they've been stored mast-in, water gets into the rigging
swages, freezes, and spalls them out regardless of what water the boat was sailed in.
There are some custom covers in my marina that are beautifully made - tight as a drum when they go on and stay that way throughtout the winter.
Just to add to hellosailors point about swages freezing - realize that freeze damage can occur with the foils on roller furling
units as well. I have older Harken
gears for my staysail and genoa
and I drop my mast
to store inside every winter. I've had water accumulate in the foil slots during the winter, freeze and cause a split in a foil section, making replacement necessary. The metal in the area of the split is pushed out, which doesn't allow the the furlers headstay car to pass the damaged area.
Now we are always careful to make sure the grooves face down to help keep water from collecting in them. Maybe the new furlers don't have this issue - my old gears have been trouble free from the word go, so I haven't kept up with the different gears on the market today.
