Simmer Sx8 SDM

Description

Simmer SX8 SDM is a high-performance windsurfing mast with 80% pre-preg carbon, built for sailors who want a quick reflex response and a light, lively rig – without compromising on durability. With the same construction principles and bend curve as the flagship SX10, the SX8 offers the best balance of performance and strength. The mast is the obvious choice for flatwater and freerace, where stability and acceleration matter.

SX8 is made from high-grade pre-preg carbon, with the resin content and distribution in the laminate precisely controlled throughout the process. The inner layer consists of 45-degree carbon weave, which controls torsion and delivers a quick reflex response, while the outer layer, with its 90-degree orientation, ensures the highest possible strength. The progressive constant curve means the bend curve is constant, but the base is stiffer than the top – this allows the lower part of the sail to generate power while the top of the rig quickly releases it again.

  • 80% pre-preg carbon: High carbon content delivers fast reflex response and a noticeably lighter feel in the rig.
  • 45-degree inner carbon weave: Controls torsion and ensures a quick, precise response.
  • 90-degree outer layer: Provides the highest possible strength and increased durability.
  • Progressive constant curve: Constant bend curve with a stiffer base for optimal power generation in the lower part of the sail and quick release at the top.
  • SDM diameter: Faster reflex response, better stability, and quicker acceleration – ideal for flatwater.
  • Compatible bend curve: Same bend curve as the SX8 RDM, the more durable option for wave conditions.
  • Recommended for race and freerace sails: The recommended mast for V-Max, 2XC, and SC Slalom, as well as a great choice for Enduro.

Technical details: 80% pre-preg carbon · SDM diameter · Progressive constant curve · IMCS 21 (430 cm) and 25 (460 cm) · Weight 1.8–2.0 kg depending on size

  • Care & Maintenance

    Maintain your carbon mast with a few simple steps so it lasts for many seasons.

    • Rinse after use: Rinse the mast in fresh water after every session, especially after use in salt water, and wipe it dry with a soft cloth.
    • Check for damage: Regularly check the mast for scratches, dents, or cracks - especially around the clamp and connection points.
    • Avoid direct sunlight: Never leave the mast in direct sunlight for long periods, as UV rays degrade the resin and coating over time.
    • Dry properly: Let the mast dry completely before putting it away to prevent limescale deposits or corrosion on metal parts.
    • Storage: Store the mast horizontally or vertically in a cool, dry place - preferably in a mast bag. Avoid leaving it bent or under heavy objects.
    • Transport: Use a mast bag or padding during transport to protect it from impacts and pressure points.
  • FAQ

    What sizes is the Simmer SX8 SDM available in?

    The mast is available in 430 and 460 cm sizes, making it a good fit for the most common freerace and race rig setups.

    What does 80% carbon mean?

    The SX8 name refers to its carbon content: the mast is made from 80% pre-preg carbon, providing quick reflex response and light weight, with added durability compared to a 100% carbon mast.

    Should I choose SDM or RDM?

    The SDM mast offers quicker reflex response, better stability and faster acceleration, making it best suited to flatwater. The RDM version is more durable and recommended for rough wave conditions.

    Which sails is the SX8 SDM compatible with?

    Simmer recommends the SX8 SDM for V-Max, 2XC and SC Slalom, and it’s also a great choice for getting the most out of Enduro sails.

    What is IMCS, and what is the mast compatible with?

    IMCS indicates the mast’s stiffness. The 430 model has an IMCS of 21, and the 460 model an IMCS of 25 – check your sail’s IMCS rating when choosing a size.

    How much does the mast weigh?

    Weight depends on the size: the 430 model weighs 1.8 kg and the 460 model 2.0 kg.

    How do I maintain the mast?

    Rinse it with fresh water after use, let it dry completely, and store it in a cool, dark place in a mast bag – that way, the carbon will last for many years.
