Extensive testing of the CST1 carbon mast was completed at Middle Bay Yacht Club, Sydney on 29th March, 2003. Bend testing was performed with a 7m span with a 25kg weight at mid-point (3.5m) and at the 2m bracket/hounds location.

Construction
Combination of Standard and intermediate carbon fibres filament wound with epoxy resin.

 

OD F/A x Side (mm)	68 x 55
Tip Diameter F/A x side (mm)	38 x 25
Length (m)	7.31
Bare Weight (kgs) conservative, strong Design	5 kgs

• Carbon is Lighter - 1530 kg/m^3 against 2700 kg/m^3 for Aluminium
• Carbon is much Stronger than Aluminium- 640 MPa against 300 Mpa (max standard Aluminium)
• Tailored Stiffness to suit - guaranteed to suit current luff rounds within 5%
• 100% repeatable (guaranteed)
• Smaller diameter (less windage)
• Does not corrode
• Fatigue resistance orders of magnitude better than Aluminium
• Life Span - pretty well indefinite with normal sailing loads apart from normal wear and tear.
• Protective coated in Polyurethane clear coat
• Cost - about that of a main and jib but does not wear out like sails
• Bonded composite track - as used on the World Champion CST 18 skiff rigs.
• Retrofit with existing mast wires and fittings to save $$ - easy fit out with normal tools.
• Two piece - join at the lower spreaders for easy stowing and transport
• Two piece - lower cost if breakages occur due to mis-adventure
• Masts are very easy to repair if broken with glue and internal sleeves
• As used by Flying ants, Cherubs, Javelins, I14s, 12 skiffs, Skates, 18 skiffs, etc , etc
