Severne Masts
2025 SEVERNE Apex Team SDM Mast
SV APEX TEAM - SDM
The highest performing, most reliable pro race mast. The Apex Team is our lightest SDM mast with a vigorous durability testing scheme behind it. The Apex Team has been through an intense development cycle and withstands the forces required by modern performance race sails. New technical features include carbon replacement where there previously were glass layers. A larger layer overlap and the addition of 90° carbon bring two significant upgrades; increased strength, and unaltered weight. The Apex Team maintains characteristics of all previous Apex masts; / ULTIMATE PERFORMANCE / INTEGRATED FERRULE / +7 MEASURED OFFSET ACCURACY / SLIPLOK PREVENTS BOOM FROM SLIDING
Our design objectives.
Achieve a higher durability mast while maintaining performance characteristics of Apex Pro masts.
What is changing?
Glass layers have been replaced with 90° carbon layers with bigger overlaps.

Severne Windsurfing RDM40 White Carbon Mast 400cm only
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.
