The Force FIVE is an evolutionary refinement of the Force R1. This 5-batten wave sail is perfect for riders who demand acceleration, power and control in offshore, sideshore and onshore surf conditions. It also provides the power and speed to serve as a high-wind bump & jump sail.

It is designed with a stable, locked-in power shape that is defined by twin scrim luff panels and a moderate aspect ratio. It also features Naishs exclusive Carbontech Construction that utilizes the most technically advanced materials available.

The Force FIVE delivers exceptional acceleration, early planing and even pressure to both hands and is favored by many heavier riders because of its exceptional power.

Standard Clew Construction

The radial clew is the strongest and lightest design in the industry. A custom titanium ring is connected directly to radial Kevlar load strips via high-tenacity nylon webbing. The Warp Kevlar taffeta leech and foot tapes carry the perimeter loads.


Tack Fairing

Durable molded EVA tack fairing that folds back for easy rigging and protects the sailors feet, mast and board. It features a grommet for the uphaul line and a mesh pocket with a Velcro closure for storing the downhaul line.


6-Ply Batten Pocket Construction

Striking a critical balance between light weight and durability, the batten pocket balances the power loads and has scuff protection on both sides of the sail.


Roller Tack Pulley

A downhaul pulley that integrates a lightweight die-cast stainless steel housing and low-friction Nylatron GSM pulleys. It provides both standard 6:1 and 4:1 rigging options. This system makes downhauling very easy and reduces wear and tear on the downhaul line.



Loop and Go

The unique geometry of our pulley offers both traditional 6:1 AND 4:1 loop-and-go rigging.


Downhaul Pocket

Secure mesh pocket with Velcro for storing the downhaul line.


Boom Opening + Position Marker

The boom opening has a long sleeve cutout for easy rigging, and features position markers that enable perfect boom positioning every time you rig.
