NeilPryde X1 Windsurf Boomm 140-190 cm

Description

Key Features
VT-Joint
The NeilPryde VT-Joint provides a stiffer boom connection and a more responsive transmission of the sails’ power while protecting the mast.
Using the VT-Joint has several key benefits: * increases contact area from the boom attachment to the mast. * it can be used on any standard diameter mast (excluding RDM’s) without the need for a shim. * reduces chance of point loading. * minimises ‘play’ between the boom and mast connection
The mast cup interior of the VT-Joint has been carefully contoured to create a V shape.
The V shape accommodates variation in standard mast diameters without the need for a shim. Slightly thinner masts simply sit further into the V while fatter ones sit lower down. The change in shape provides a 2nd point of contact between the cup and the mast creating a tighter connection and a greater transmission of power than ever before.
The VT-Joint is now standard on all new NeilPryde booms with an oversized mast cup material composition tailored to suit each boom type:
X1 – Oversized mast cup in glass fibre reinforced injection moulding X3 – Oversized mast cup in glass fibre reinforced injection moulding X9 – Oversized mat cup in forged carbon composite material
X9 Custom Tails
* Customized carbon tails for Wave, Slalom and Racing booms. * Hollow box section tubes. * Square profile. * Increased torsional rigidity. * Optimized performance / weight ratio.
S-Shape Profile
In contrast to a traditional boom that has convex and straight outline sections, all X3 booms and 140 & 160 X9 boom lengths 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.
Mast Shim
Customized carbon tails for Wave, Slalom and Racing booms. Hollow box section tubes. Square profile. Increased torsional rigidity. Optimized performance / weight ratio.
Twin-Pin Lever Actuated Trim Lock Adjustment System
Featured on all booms for ease of adjustment (except the X9 race booms). The Twin-Pin design provides optimal load distribution and a stiff connection between the boom body and tail end.
Aerodynamic Boom Lever
* Reduced surface area. * Lighter weight. * Easy locking and opening.
VT Joint Lateral Locating Button
Locates VT joint side to side on the boom head and prevents side to side movement, while allowing articulation.
