Solid Bronze Sailboat Coaming Board Winch Mounts. These mount over the Teak Combing boards on a sailboat for jibsheet or Spinnaker winches. Will hold up to a 4 1/2" diameter winch. They are used with a wood mounting pad, the winch is mounted to the pad then the pad is bolted to the mounts, that way any bolt pattern on the winch will work. Made of Heavy Cast Bronze. Please see pics for dimensions.
