I designed my bimini
so this wouldn't happen, but it is close.
(and others perhaps) made a ratcheting winch handle that deals with this situation, and I bought one on eBay years ago just in case it became a problem. Years previously, Practical Sailor featured a German ratcheting handle, but when I was searching, I found nothing about it.
It's surprising that no one makes one. You could make one out of a ratchet wrench, I suppose, but it would rust.
