Severne Windsurfing RDM40 White Carbon Mast 400cm only
Temporarily out of stock, please call - 023 9258 2614
The RDM40 range of masts gives users who would normally not have the budget for the mast and sail to get both. This mast is heavier than the higher carbon content but has the critical bend curve Severne require to work correctly.
The relationship between the mast and sail needs to be matched with finite detail. The correct curve and stiffness ensures that the response, shaping and twist are consistent with not only the original design objectives but also with the controlled conditions we test each and every one of our sails.
At Severne, our analysis of mast performance extends far beyond the two dimensional IMCS system with only 3 reference points. All Severne masts are tested at 7 designated offsets and computer faired to precisely mirror the luff curve of the sail.
Every mast in every range is produced using pre-preg carbon construction. This way the resin consistency and content can be managed down to sub millilitre perfection and the fibre content and bias controlled, which optimises strength and reduces weight.

TRIPLE XTENSION
3 PULLEY RDM EXTENSION.
With more people running freeride and slalom sails on RDM masts, the necessity for a 3-pulley RDM extension became obvious.

Perfectly matched to any sail with the 4-roller tack pulley, the Triple Xtension also suits sails with the 3-roller tack pulley. Other features include Dyneema rope and an integrated hook to anchor the tack strap.

Severne Cyclops RDM Mast Extension
RIG YOUR SAIL IN UNDER 1 MINUTE
The CYCLOPS extension has a single pulley for rapid loop ‘n go rigging. Simply pass the loop of rope through the tack pulley on the sail and hook it over the single pulley on the extension. A single pull applies full downhaul tension in seconds. All the ropes and pulleys are kept in perfect alignment to eliminate a lot of the friction and makes up for any loss of leverage from less pulleys. A built-in handle negates the need for any tool, and stuff into the downhaul pocket on the sail. Formuline rope is used to further reduce friction and minimize rope wear. Faster, simpler rigging.
