Severne Triple Xtension Carbon RDM
TRIPLE XTENSION
3 PULLEY RDM EXTENSION.
With more people running freeride and slalom sails on RDM masts, the necessity for a 3-pulley RDM extension became obvious.
Design focused on reducing downhaul friction for easier rigging. Careful attention to rope alignment and pulley spacing has enabled significant improvements. Perfectly matched to any sail with the 4-roller tack pulley, the Triple Xtension also suits sails with the 3-roller tack pulley. Other features include Dyneema rope and an integrated hook to anchor the tack strap.

Duotone Power.XT 2.0 Alloy Windsurfing Extension
-
An inspiring (r)evolution – the POWER.XT 2.0 can do much more and do it better than the previous model. And as POWER.XT 2.0 SLS RDM 36 it is also the most lightweight ratchet extension of all time! Beyond the basic idea, the POWER.XT 2.0 has almost nothing in common with the previous model any more. From the extremely solid ratchet mechanism plus lever to the simplified release mechanism, the high-strength Lyros® Dyneema harness downhaul lines and the option to retrofit the damper function – everything has been radically upgraded. The latest version comes with a completely new adjustment ring, which offers a unique feature: based on the tried-and-tested SDM adjustment ring, the RDM version now for the first time ensures that the aluminum tube does not come into contact with the mast anymore, which avoids any contact corrosion. No other RDM extension can offer that! In order to guarantee the same durability despite the reduced diameter, a double-walled sandwich construction of 7075 aluminum outer tube and ovalized T8 inner tube is used (patent pending). For many years, the POWER.XT has been the benchmark when it comes to extensions with trimming tools. Those who use it will never want to do without it again. Thanks to the integrated lever, it overcomes even the strongest downhaul forces, enabling perfect re-trimming or fine-tuning even when on the water. Even children could handle the extreme luff tension of modern slalom sails, each profile can be adjusted to millimetre precision in a matter of seconds. The 15 cm long lever and the ratio of 1:60 enable trimming without any noticeable effort.

Streamlined RDM Windsurfing Mast Extension
Aluminium
Red-line extensions start with custom 32 millimeter, 6061 T-8 “drawn” aluminum tubing. The kind of tubing they use to make aircraft. Our tubing is engineered so that with its large diameter, the wall thickness can be thinner so the overall result is an incredible high strength, to low weight ratio. This formula has been proven with our years of experience. The holes are precision punched, then the tube is red anodized in and out, permanent laser numbered 2 centimeter settings. The adjustment settings are held with a hard anodized aluminum collar tethered with a spectra line to a stainless steel pin. Fail-safe and virtually break proof. Finally we attach our new beefy “Power-Six” super powerful 6:1 downhaul cleat with large diameter pulleys, perpendicular for power, easy rigging and no crossed lines. A tough Dyneema “super downhaul” line is included.
Severne Cyclops HD RDM Aluminium Mast Extension 24+36cm
Severne Cyclops RDM Mast Extension
RIG YOUR SAIL IN UNDER 1 MINUTE
The CYCLOPS extension has a single pulley for rapid loop ‘n go rigging. Simply pass the loop of rope through the tack pulley on the sail and hook it over the single pulley on the extension. A single pull applies full downhaul tension in seconds. All the ropes and pulleys are kept in perfect alignment to eliminate a lot of the friction and makes up for any loss of leverage from less pulleys. A built-in handle negates the need for any tool, and stuff into the downhaul pocket on the sail. Formuline rope is used to further reduce friction and minimize rope wear. Faster, simpler rigging.
