X3 arms made of T6 series alloy

Higher level of heat treatment attained, creating stiffer and stronger arms. Improved corrosion resistance in salt water 28mm Handgrip diameter on all 140 & 160 booms - maximum control and comfort 30mm Handgrip diameter on all 180, 200, 225 & 260 – optimum stiffness and performance

New boom lever

Reduced surface area
Lighter weight

VT-Joint lateral locating button

Locates VT joint side to side on the boom head and prevents side to side movement, while allowing articulation.


VT-Joint

Standard on all NeilPryde booms
The VT-Joint provides a stiffer boom connection and a more responsive transmission of the sail's power while protecting the mast.

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.


Nylon slide plugs in tail extensions

Reduces friction with boom arm and ensure smooth adjustability

Mast Shim

All 140 and 160 booms are delivered with a RDM mast shim.


Harness line SCALE

For easy harness lines adjustment


The Mast Cup

The mast cup interior of the VT-Joint creates a V shape that
accommodates variation in standard mast diameters without
the need for a shim.

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.
