Details

Ball raced head fitting + backstay crane. Suitable for Naviga 1M, US1M, Marblehead, Ten Rater, 6 Metre and similar sized boats.

Ball raced head fitting + backstay crane. For 8, 10 or 12 mm mm Ø carbon tube with 1 mm wall thickness. 

A   We use 20 mm wide Mylar tape to reinforce the top of the mast tube. You can also use deck patch material or carbon tow and epoxy resin.

B   On Marblehead class A1, B1 & C1 rigs you should add the upper limit mark to the rotating arm.

C   When used with eyelet luff sails it is useful if the upper edge of the arm has a series of notches. Moving the head of the sail aft allows the top of the sail to be flattened (useful when over pressed) and twist off more.

D   Move the backstay as far forward as possible on the carbon crane without conflicting with the mainsail leech in order to reduce mast bend and increase forestay tension. When it is in the correct place, use a spot of cyanoacrylate glue to bond it in place.

To attach a SAILSetc wind indicator drill a 1.6 mm Ø hole in the mast where shown and use an O ring, ref. 82-010, to secure the wind indicator. Note the bend in the wind indicator wire. The lanyard and clip hook are a safety measure to avoid losing the wind indicator.

This item combines the head fitting and backstay crane into a single unit suitable for use with almost all M and 10R rigs where 8, 10 or 12 mm Ø carbon tube is used for the upper mast. In this robust unit the backstay crane and head fitting are captive preventing loss or misalignment.
