Mast Base and Extension

The North EXP Base with the tendon is the proven windsurfing mast base with tool-less mounting and easy adjustment.

The Duotone UNI.XT – the most technically advanced and yet the most lightweight standard aluminium extension we have ever built. Now also built using AERO carbon technology to create the most lightweight extension in the world. When it comes to standard extensions, everyone has probably experienced some nasty surprises at some point. They rarely fit with the rope alignment on the sail, most of them need high downhaul forces, and more often than not the mechanism for adjusting the height is extremely fiddly. Before designing the UNI.XT we analysed all of these issues in detail and came up with workable solutions. The strong and super-solid UNI.XT extension may look like numerous other standard extensions at first glance, yet it is replete with innovations which make it a far superior product.

0-16cm, 0-24cm, 0-36cm

The Severne HD RACE EXTENSION SDM comes in 3 sizes to compliment the racing and freeride range; 16cm, 24cm & 36cm. Powerful coil spring catch and release. Aligned triple pulleys and cleat for easier down hauling. Stainless steel automatic hinged collar system. Stainless steel button and mechanism for improved reliability. 0cm setting for increased functional range

The Neilpryde MXT mast extension, Used by most sailors on the PWA TOUR, the Mono-Button Mast Base and Extension System (MXT) has been designed to offer a secure, heavy duty connection and ease of operation. The MXT Extensions are fully integrated with stainless steel cleat/pulley bottom assemblies offering the best weight to stiffness ratio and creating very light but also very strong extensions.

The weight has been reduced by eliminating all unnecessary plastic while increasing the cross- section of stainless steel parts for increased strength.This part can now withstand over 900kg of downhaul load twice as much as used on the largest racing sails.

The special geometry with tilt bottom pulley makes perfect sail pulley/rope alignment. This allows the sail to be downhauled all the way down (block-to-block) and it reduces downhauling friction.

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.

34cm SDM, 34CM RDM, 48CM SDM

The Neilpryde UXT mast extension system allows us to use a continuous diameter all the way down.

The outer diameter of the upper mast cap is larger than the diameter of the extension tube. This, combined with the stepped collar of the Clamshell, creates a cavity thus preventing the carbon mast and alloy tube to be in contact, preventing oxidation and corrosion.

STAINLESS STEEL BUTTON AND MECHANISM

DOUBLE STAINLESS STEEL PULLEYS FOR LESS FRICTION AND GREAT DURABILITY

SOLID ALUMINUM TUBES
