- Hand grips have harness line scale for easy harness line adjustment.
Detailed installation instructions included.
- Allows you to tune your rig as easily while sailing as you can when on the beach – regardless of the type of NeilPryde boom you use.
- Maximises the tuning range of your sails. An absolute essential for racing or large freerace sails.
- Designed to be used on any X1, X3, X9, RS:One and RS:X boom.
THE MAST CUP
The mast cup interior of the VT-Joint creates a V shape that accommodates variation in standard mast diameters.
The V shape provides a second point of contact between the cup and the mast creating a tighter connection and a greater transmission of power.
Slightly thinner masts simply sit further into the V while fatter ones sit lower down.

X9 – Oversized mat cup in forged carbon composite material
In contrast to a traditional boom that has convex and straight outline sections, the NeilPryde 140 and 160 booms have an S shape concave section at the highest loading point (the back hand section). With traditional booms, as there is more force at the backhand section, (such as when landing jumps or sailing overpowered), a straight/ convex outline is free to bend out, making the boom feel soft and actually making the sail profile deeper as the boom gets shorter. On the "S" boom this force is applied against the concave "S" section resulting in much improved stiffness as well as keeping the sail profile stable as the boom length does not change under load.
FORGED ALUMINUM HEAD
Pressure Flow Forging – an innovative technology that allows for shaping of exceptionally stiff aluminium tubing. By applying this technology on all our X3 booms, the NeilPryde R&D team have managed to create the lightest, strongest and most rigid aluminium booms available on the market.
‘Pressure Flow Forging’ represents a real breakthrough in boom shaping as the metal is allowed to ‘flow’ rather than stretch into shape. Fluid is injected at very high pressure into the aluminum tube that causes it to expand until it matches an external female mold. This process increases the density of the aluminum in all areas and provides the ability to control wall thickness, allowing for the creation of complex shapes that result in a far stronger head. Further, we chose to put the boom arms inside the head tube and this results in an outside diameter of the head being increased and bringing a further increase in rigidity and strength. As a final production process, this already high tech piece is heat tempered to create highest stiffness and strength.
'NEW SCHOOL' HEAD PROFILE
For the first time ever, the new X3 aluminum and hybrid series booms are also available in the 'new school' head profile in both the 140 and 160 series. The somewhat antiestablishment shape ensures a comfortable ride with less fatigue because your body position is altogether more natural.
Now, your wrists are aligned with your forearms regardless of where you hold the boom, meaning your hands are no longer overstretched, forced or twisted. When gusts exhort their authority, the new boom profile gives you the right to answer back with your leading hand more naturally closer to the mast, giving you unprecedented control and confidence.
