Obviously, your winches are one the most important, and expensive pieces of equipment on your boat. Is it worth it to get covers for them? I can see it both ways:
Pro: they sit outside in the elements, all the time. Shouldn't they be protected?
Con: they're designed to be outside. Freshwater rain on them might not be that bad--rinse away the salt and dirt. Additionally, metal usually does better in the elements when exposed to fresh air. Closing it up under a cover could restrict airflow, and promote corrosion.
What do you think?
I to would like too hear some info on this. I was going to make Winch covers to keep them out of the elements, never considered that they might have problems. You're winch covers would only be on while at anchor, so I guess it depends on how much time you spend on the hook?
