S-shape profile

The clock has long been ticking for conventional boom design, and that’s because the performance has been held hostage by simple physics.

It’s simple really; as wind pressure increases, a straight or convex boom effectively becomes shorter as it bends in response to increasing sail load, making the sail fuller, less efficient and harder to manage.
(Ask your forearms, they’ve been putting up with it for years). Everybody make way for the new convention; the ‘S’ profile boom.
The unique shape commands the sail to retain its shape and length whatever the breeze, providing a more stable and predictable delivery, and more useable power.
The ‘S’ profile is standard this season across the entire NeilPryde range, so everyone can get their hands on it.
