The
SX4 is the best choice for novice sailors who wants to bring their
windsurfing to an experts level. With a 40% carbon content the SX4
delivers slightly softer handling which is ideal when you are starting
out your windsurf career. Designed with the same bend curve as the
higher level Simmer Style masts and using only the finest pre-preg
carbon materials the SX4 delivers performance and superb durability.

The
bend curve of the SDM and RDM’s are compatible with one another, but
the RDM’s are more durable, therefor more suitable for punishing wave
conditions. SDM’s provide a faster reflex response, better stability and
faster acceleration, therefor more suitable for flatwater sailing. The
SX4 is our recommended mast for the Novex sail.
