NG1 Masthead Spinnaker Crane: NG1-2:
Heavy SS Masthead Spinnaker Crane is designed to attach to standard Isomat NG1 Masthead Rig Masthead.

This method of running spinnaker halyards has less friction and eliminates the chafe on halyards that is inherent in the standard internal halyard design - it is the only choice for long-distance racing or cruising. Halyards can be led internally; running from the swivel block to an entrance 5-8 feet down from the masthead, but this method does add a potential chafe spot. Attaches with (2) 1/4" bolts and locknuts, and (2) 6mm (3/16") screws that go into the threaded holes for the masthead Cover Plate screws. SS Plate is (maximum) 3 7/8" long x 4 3/8" wide x 3/16" thick, and projects 2" forward of the masthead. Mounting requires drilling (2) 1/4" holes in the masthead. Unit comes complete with fasteners.
