Simmer Sx6 Rdm 370

Maintaining your windsurf mast

Rinsing: Rinse the mast with fresh water after every session, especially if you’ve sailed in salt water. Salt residue can degrade the material and cause the joints to stick over time.

Inspection: Check the mast regularly for impact damage, cracks or delamination - especially after a hard landing or collision. Also check that the two mast halves separate easily and that the joint is clean and dry.

Drying: Let the mast dry completely before putting it away. Separate the halves while drying so moisture doesn’t remain in the joint.

Storage: Store the mast horizontally or vertically in a cool, dry place out of direct sunlight. Avoid leaving it in a hot car or at the bottom of a rig, as pressure and heat can damage the carbon material. Ideally, store it in a mast bag for extra protection during transport.

Assembly: Never push the mast halves together at an angle - keep them aligned and apply firm, even pressure. This significantly extends the life of the joint.

What material is the Simmer SX6 RDM 370 made of?

The mast is made from high-grade pre-preg carbon with a 60% carbon content. The resin content and distribution are precisely controlled during production.

Is the SX6 RDM 370 compatible with all windsurf sails?

Yes, the mast can be used with all Simmer Style sails, and its bend curve is compatible with both RDM and SDM variants.

What does RDM diameter mean?

RDM stands for Reduced Diameter Mast, meaning a mast with a reduced diameter. It is more durable and therefore particularly well suited to demanding wave conditions.

How much does the SX6 RDM 370 weigh?

It weighs 1.8 kg, making the mast easy to handle while rigging and on the water.

What is the mast's IMCS?

The SX6 RDM 370 has an IMCS of 17, which indicates the mast's stiffness and should match the sail's recommended mast stiffness.

Is the mast suitable for beginners?

Yes, the SX6 is designed for windsurfers of all levels and is a budget-friendly choice with good performance.

Why is the base stiffer than the top?

The mast's progressive constant curve means the lower part of the sail generates power, while the top quickly releases power - this provides good sail dynamics and control.

How can I best take care of the mast?

Rinse it with fresh water after use, let it dry while disassembled, and store it in a mast bag in a cool, dark place for the longest possible lifespan.
