Details

High modulus carbon fibre round tube, 16.5 mm outside Ø, 14 mm ID, 1.25 mm wall thickness, 93 grams/metre.

Made of high modulus UD carbon fibres to provide a tube with very high stiffness for its weight and diameter.

Use for the lower section of a mast for an A Class or similar size boat with 14 and 12 mm diameters higher up.

Offcuts of smaller diameter carbon tubes are suitable for headsail booms. Offcuts of larger diameter carbon tubes are suitable for main booms. They can also be used for adding reinforcement internally or externally, for example: at the swivel position on a headsail boom, at the kicking strap attachment position on a main boom, and at the gooseneck position on a mast.

Graphs of 'Stiffness of mast spar material against diameter' and 'Stiffness of mast spar material against weight/metre' are shown in the thumbnail sketches. The suitability of any SAILSetc mast spar material for its intended application can be checked using the graphs shown in the FAQs section - link.

Guidance on pens suitable for marking difficult surfaces - here.

  • Cutting carbon
  • Always wear a mask when cutting and abrading carbon fibres.
  • Clear up the work area carefully afterwards.
  • Use a wet rag to mop up carbon dust rather than a vacuum cleaner or brush.
  • Before bonding
  • Check each piece of mast tube for bend.
  • Arrange to use them so that the bend in the mast will be forwards going upwards.
  • Abrade all surfaces to be bonded with abrasive paper
  • Use Acetone, alcohol or methylated spirit to clean all surfaces to be bonded.
  • Bonding
  • Use liquid epoxy to wet all surfaces to be bonded
  • Then add thickened epoxy to the surfaces that will be bonded
  • Avoid applying local pressure that may distort the parts during bonding
  • Avoid raising the temperature of the work piece until the epoxy is cured
  • Allow the work piece to cool gradually after post curing.
