The modern epoxy mast with 40% carbon content, which is also available as a slim RDM model. Dynamic, solid and, thanks to its small diameter, very easy to grip as an RDM during manoeuvres. Six RDM lengths from 230 to 430 cm, as well as two SDM lengths, cover all conceivable sail sizes (including children's sizes up to 1.0 m²). The EPX.40 range works with almost all sails, regardless of the specific brand.
