Sitting squarely in the center of the range, the Force FOUR strikes a perfect balance between the solid power and versatility of the Force FIVE and the dynamic and responsive Force THREE. Thanks to its smooth twist and wide tuning range, this sail is more forgiving than the Force FIVE, while still retaining plenty of low-end performance and control.
The Force FOUR is the ideal sail for riders looking for a lively and lighter version of the classic, genre-defining 5-batten Force. It is also a great choice for Session riders looking to upgrade their quiver.
Sizes: 3.4, 3.7, 4.1, 4.5, 4.7, 5.0, 5.3, 5.7
- 4 Battens = Good stability + very responsive

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.
Durable molded EVA tack fairing that folds back for easy rigging and protects the sailor’s 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.
The unique geometry of our pulley offers both traditional 6:1 AND 4:1 “loop-and-go” rigging.
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.
Naish sails include comprehensive lightweight PVC scuff protection for both sides of the sail.
