I use the one pictured above that has the blue bungee attached. That is called a Carbine Hook and is made by Wichard. I do not use the bungee as pictured but the
hook to bridle is my set up. I use the biggest one they make for hooking to
mooring balls. It works great and fits all moorings in the BVI/
caribbean. This is the fastest way to take a mooring that I have found. I do not use this for a chain hook though.
I use a more traditional chain grabber with
bridle when
anchoring on the hook. It works great too. Of course, with a cat, bridles tend to
work smoother than on mono's.
