As Reduced Diameter Masts or "skinnies" become even more commonplace at our local sailing sites - North Sails introduce their very own version.
Labelled as the first truly functional needle mast - The North PLATINUM RDM is aims to set the new standard in skinny mast technology.
According to North - the difference is in the new conical shape of the top. North's own tests revealed that cylindrical needle tops perform poorer than ordinary "thick“ masts since the top‘s construction does not permit proper function.
With the new PLATINUM RDM however, the rig does not only benefit from the lower diameter’s superior aerodynamics but also takes advantage of the needle shape’s increased dynamics.
Another major advantage: due to its conical shape, the needle top can now be stowed in the base for transport.
Just compare the weights of these RDM masts with mainstream ordinary masts - to see why the industry is keen to promote these masts to the every day sailor!
