I do like the horizontal windlass over the vertical. I ran a vertical for 6-7 years and then switched to horizontal now for 5+ years. The vertical will induce a rotation into the chain so then everyone adds a swivel to reduce this. It still happens. With a horizontal the chain does not take up a twist as it comes over the the gypsy and drops into the locker with no twist. Also a horizontal is simple to install, just bolt it down and that is it. Horizontal requires a large hole to be cut.
Many of us have taken to the LOFRANS brand of windlass

I have the TIGRESS and think it is amazing. I would buy it again.
