Details

Head fitting - 11 mm Ø. For 11 mm Ø round mast tubes and 11.1 mm alloy GROOVY mast section. Suitable for use with 36R, IOM and similar size boats.

Now much copied, this is the original mast head fitting that is a push fit into the top of a mast. The design incorporates the upper limit mark, a hole for the mainsail head swivel and attachment for the backstay crane.

Use backstay cranes ref. 22-040 or 22-025 (22-025 for No 3 rig only). Use 1.5 mm Ø wire for the mainsail head swivel ref. W150.

The original version is grey colour and meets the rule requirement for the limit marks to contrast with the colour of the spar.

On the standard version the special lug provides attachment for SAILSetc wind indicator ref. 100. Drill a 1.6 mm Ø hole in the mast and use an O ring, ref. 82-010, to secure the wind indicator. No lug provided on the revised version.

The revised version (not suitable for use with GROOVY mast) with the central hole for the rotating wire is black and may need a coloured band added if used on a black mast spar. This version has to be used with backstay crane ref. 22-040.  Suitable for masts with a wall thickness maximum 0.60 mm. By rotating around the mast centreline the projected area of the head of the sail is increased marginally.
