One piece clip on aerofoil section spreaders, To suit various classes.

For 11, 12, 14  or 16.5 mm diameter mast.

Those fopr 11 and 12 mm diameter masts have holes at 60, 55, 50 and 45 mm. The aerofoil section is angled downwards to align well with the oncoming air flow. The unit is designed to be a clip on/clip off fitto the mast.

Those for 14 mm or 16.5 mm diameter mast have holes for shrouds at 100, 90, 80 and 70 mm. The spreaders are tilted upwards going outboard from the mast and the aerofoil section is angled downwards to align well with the oncoming air flow. The unit can be used as it is and added to the mast before other fittings are added but it is advisable to make the unit a clip on/clip off fit by removing a section of the boss.

Choose from 5 degree or 10 degree sweepback angle.

An adjustable spreader set for A Class and similar large boats can be found at ref. 21-ADJ.

The aerofoil section spreaders reduce the windage of the rig significantly compared to spreaders of round section and comparable stiffness. Spreader drag is reduced by approximately 90%.
