Alloy GROOVY - 12.7 mm Ø
Details
Alloy GROOVY, 12.7 mm Ø. Natural anodised colour, 70 grams/metre, maximum 2000 mm long. 15 mm at each end may be imperfect where the anodising clamps have been attached.
It is expensive to send full length pieces so consider having several pieces sent at the same time and split the cost of transport with others. 1.0 metre pieces can be sent more economically and can be made into masts using joint piece ref 18-127. The joint piece is included if the cut option is chosen.
Pre-bend can be added to the mast if you wish. And the holes for spreaders, shrouds and forestay can be drilled and sail limit marks applied too.
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.
