UNIVERSAL ALU MAST TECHNOLOGY
In order to increase both lateral and torsional stiffness of the ALU mast, we have redesigned a new mast profile and mould. The new mast now has a maximum thickness of 18mm and its profile is also proportionally thicker towards the trailing edge in order to minimise twist. We have also introduced a new middle stringer structure in between the two screws that have allowed a higher lateral stiffness. The incorporated top plate is smaller and shorter than the Y25 UNIVERSAL ALU MAST resulting in a lighter weight. The new ALU mast has an unparalleled TWIST of only 2,2 cms, feeling as torsional stiff as a full hi-modulus M40J Carbon mast !!!
With a Tensile modulus (stiffness) of 54,7 Msi (million pounds on square inches) and a Tensile strength (axial stress amount before breaking) of 640 Ksi ( kilo-pound per square inches) the TORAY® M40J carbon is the best PAN BASE carbon fiber available in STD weights for premium sport goods applications.
Please realise that the MJ line of Carbon fibers from Toray® are the most expensive carbon fibers in their range and very limited in terms of availability with the longest lead-time from order. Please do not only consider a Carbon mast for its lighter weight compared to an Aluminum mast. Using a lower modulus carbon fibers it is possible to make a lighter mast, but it will most likely have poor torsional and side stiffness. Often a light weight mast is synonymous of poor stiffness and durability. Always choose quality when hydrofoiling, and quality #1 on a hydrofoil mast is: STIFFNESS.
