NG-80 Mast – Masthead Parts NG2 Mastheads are cast from high-strength Aluminum alloy, and are welded into the mast section. Isomat NG2 Mastheads are easily identified by having 4 sheaves (or provision for 4 sheaves) side by side, on the forward side. For Details, See: NG2 Masthead Assembly. |

NG2 Masthead Cover Plate: NG2-1: Cast aluminum Masthead Cover Plate for NG2 standard Masthead. Masthead Cover Plate also provides level surface for mounting Anchor light and has holes and slots for exiting other electrical wires. Unit is 10 1/4" (260mm) long (maximum) x 7 1/8" (180mm) wide, and is fastened with two (2) 6mm screws, NG2-1S, that thread into tapped holes in Masthead.

| NG-2 Masthead Spinnaker Crane: NG2-2: Heavy SS Masthead Spinnaker Crane is designed to attach to standard Isomat NG2 Masthead. Crane allows for off-center attachment of one or two standard swivel blocks for external spinnaker halyards, See Spinnaker Halyard Blocks. 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 (4) 5/16" (8mm) bolts and locknuts. SS Plate is (maximum) 4" long x 5 3/8" wide x 1/4" thick, and projects 1 3/8" forward of the masthead. Easily positioned on the masthead, mounting requires drilling (4) 5/16" holes in the masthead. Unit comes complete with fasteners. |

NG-80 Mast - Welded Mast Base Exit Boxes Some Isomat Masts have Welded Exit Boxes at the base of the mast for leading internal halyards out of the Mast at Deck level, rather than higher on the mast using standard Exit Plates. Halyards exit the Mast angled aft, toward the cockpit, eliminating the need for any additional hardware at the base of the Mast. Welded Exit Boxes are especially common on Cruising Yachts. The NG-80 Mast Section would normally use NG2 Welded Exit Boxes, See Welded Mast Base Exit Boxes. |
