At Hall Spars we use our company’s experience and expertise to produce high performance products in an efficient way.
Our mandrel-molded process involves building seamless tubes by laying up unidirectional pre-preg carbon around a male mandrel.
During this process, we ensure to bring you a clear understanding of the performance benefits of every detail, guaranteeing that every dollar spent delivers where it counts.
At Hall we offer you the freedom of choice, as we work with three specific classifications of carbon modulus: standard modulus, intermediate modulus and high modulus. Hall’s mandrel molding process is ideal for all these materials, even with the process-sensitive more brittle high modulus materials.
Smooth and Seamless
During our process, every layer of carbon is carefully compacted before the next layer is applied, ensuring wrinkle-free laminates while minimizing voids.
Our seamless masts have tooled, smooth inside surfaces, providing highly accurate surfaces for internal mounting of close-tolerance computer-machined fittings. Outside surfaces are also extremely smooth allowing them to be clear-coated without the need for weight-adding fairing.
Our mandrel-molded seamless process maximizes mast stiffness-to-weight ratios. This extra lightness will give your yacht the edge you need to win the race.
Ultimate Precision and Refinement
Our materials promise very accurate laminate thicknesses- to a fraction of a millimetre. To optimize overall bend characteristics, strategically applied layers are placed exactly where needed, maximizing tuning and performance potential.
Our commitment to total performance extends well beyond the mast tube to the smallest of details. Knowing that a scant millimetre difference can mean a speed gain, we work closely with the boat and sail designers to optimize the relationship of mast, sail, and boat.
