Reduced diameter masts are often the first choice for wave and big action sailors. Their narrow diameter and thicker walled configuration makes them stronger than an equivalent standard diameter mast. Many sailors prefer the feel of a skinny mast in transitions where its narrow diameter makes it easier to grip. The RD Wave uses 100% carbon fibres and is built to the same specification as the latest Pro Series 100, with Kevlar woven reinforcement at the base and in the boom area. The narrower diameter of the lower part of the mast has a significant effect on how it will match the sail's luff curve. We've made a corresponding adjustment to the mast's bend curve, in order to achieve a perfect fit with conventionally cut sails. Recommended for hard use in all Wave, Freestyle and High Wind sails.
