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.

Simmer SX10 100% Carbon SD Mast
SX10 SDM
100% PRE-PREG CARBON // PRO RACE
The SX10 presents the highest performance pro race mast. This is our lightest SDM mast with the fastest reflex response for ultimate performance for turbo-charged acceleration, an extremely wide wind range, and lightweight handling.
The SX10 SDM are designed from 100% top grade and high tensile strength pre-preg carbon. This technology ensures optimum control of resin content and resin distribution throughout the laminate. The carbon layup features and inner layers of 45-degree carbon weave control torsion and quick reflex response. The outer layer of carbon has a 90-degree orientation for the highest possible strength.
The SX10 mast features a progressive constant curve which means that the bend curve is constant but the base is stiffer than the top. This provides optimal sail dynamics allowing the bottom of the sail to generate power, and the top of the rig to quickly release power.
The mast is the spine of the rig, so to get the best possible performance out of your rig, choose SX10.

Simmer SX8 80% Carbon SD Mast
SX8 SDM
80% PRE-PREG CARBON
The SX8 presents high carbon content for quick reflex respons that will lighten the feeling of any rig. Using the same high performance construction and bend curve as the SX10, the SX8 offers high-end performance with added durability therefore it is the best compromise between performance and durability.
SX8 stands for 80% carbon content. They are designed from a high grade pre-preg carbon. This technology ensures optimum control of resin content and resin distribution throughout the laminate. The carbon layup features a inner layers of 45 degree carbon weave to control torsion and quick reflex response. The outer layer carbon has a 90 degree orientation for highest possible strength.
The SX8 mast feature a progressive constant curve which means that the bend curve is constant but the base is stiffer than the top. This provides optimal sail dynamics allowing the bottom of the sail to generate power, and the top of the rig to quickly release power. 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 Simmer wavesails are developed on the SX8 RDM and this is the mast that we recommend for this reason. The SX8 SDM is the recommended mast for VMax and 2XC and SC Slalom.
For perfectly tailored rig synergy and durability choose the SX8.
