Spreader attachment for round mast and the SAILSetc aerofoil section spreaders.
Choose the sweep back angle and spreader length to suit your application, 0, 5, 10 or 15 degree sweepback angles, and 50, 75 or 100 mm spreader lengths.
Spreader tips are supplied if spreaders are chosen.
Generally the length of the spreader bar will be about 60% of the distance between the mast and the shroud attachment at the deck. This makes the 50 mm size ideal for IOM class. The 75 mm length will suit most M and 10R.
The SAILSetc spreader material is a push fit into the spreader attachment, can be removed for transport of the rig or left in place. The spreader attachment can be permanently fitted to the mast or can be made a snap on/off fit by removing part of the tube. The spreaders are angled downward (fore and aft) so that they are aligned closely with the air flow over the mast and angled upward (transversely) to suit the general angle of the shroud.
