Next step: Does anybody know the name of the wire cage thingy that one installs over the chimney to keep the sheets from fouling on it? And is it purchased or custom fabricated?
Yes, that info would be helpful. I have an unprotected vent on the cabin top too. The vent is between the shrouds and the mast so its probably unnecessary, but you know it would happen during at the worst time, so why not protect it.
