Andersen makes a 9.5:1.
Less than that and you are probably talking an ungeared winch.
Perhaps you could use a "Wincher", the blue rubber ring.

has anyone heard of low ratio (say, 6:1) self tailing winches? I really
dont need a high powered wicnh for my boat, but it sure would be nice to
have a couple of self tailers as well as a couple of standards to make
life a bit easier as i mostly sail solo. The offerings ive seen from the
big companies only have self tailers in 16:1 and better and start at
around AU$600

Thanks,
Shaun
