Severne HD Race

FAQ

What does HD mean in the Severne HD Race mast extension?

HD stands for Heavy Duty. The Severne HD Race SDM is designed for maximum durability and uses a 33% thicker wall thickness as well as a larger outer diameter to reliably prevent bending and breaking.

For which masts is the Severne HD Race 36 cm suitable?

The HD Race is an SDM extension (Standard Diameter) and therefore fits all windsurf masts with the SDM standard diameter. The 36 cm version offers extra adjustment length when more height is needed on the rig.

What adjustment length does the Severne HD Race SDM have?

The version offered here has an adjustment length of 36 cm and is therefore the longest of the three HD sizes (16, 24 and 36 cm). This makes it particularly suitable for wave sails and setups that require more boom height.

What material is the HD Race 36 cm made of?

The HD Race consists of solid aluminum tubes, combined with a Dyneema line and a stainless steel mechanism with an automatic hinge collar system.

How heavy is the Severne HD Race 36 cm?

According to the manufacturer, the 36 cm version of the HD Race weighs 0.73 kg and is therefore robust, but absolutely suitable for everyday use in race and freeride setups.

Which sails is the HD Race compatible with?

The aligned triple pulleys are designed for Severne 3- and 4-pulley sails and enable smooth, effortless lowering even at high downhaul tension.

Can the extension be set to 0 cm?

Yes, the HD Race has a 0 cm setting, so it can be compactly fixed when needed and is immediately ready for use.

Who benefits from the 36 cm version compared to 16 or 24 cm?

The 36 cm version is ideal when additional length is needed on the rig, for example with larger wave sails or if you want to rig flexibly between several sail sizes. For pure slalom setups with minimal weight, the 16 cm version is the lighter alternative.
