It looks like a winch. It mounts like a winch. It cranks like a winch. It’s not a winch.
It could act more like a really large ratcheting foot, cheek block, or even a ratcheting line diverter in the pit. The SnubbAir provides lots of line-holding power even without a winch handle. That muscle could become very popular on an A Scow or a powered-up sport boat where the spinnakers can be more than a handful. Even better, you can just flip the sheet off the drum and jibe. If you need even more holding power, wrap the sheet around the SnubbAir twice or use a winch handle with the optional adapter.
