High modulus carbon fibre round tube, 1 mm wall thickness, 35 grams/metre, 1000 mm long. Made of high modulus UD carbon fibres to provide a tube with very high stiffness for its weight and diameter.
Use for the upper section of a lightweight mast for a Marblehead or Ten Rater or similar size boat with 14, 12 and 10 mm diameters below. Use for the upper section of a mast for a US 1M or Mini 40 with 10 mm diameter below. Use for headsail booms for Marblehead and Ten Rater No 1 rigs.
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.
