The sail utilizes the wind power as an effective way of propulsion. That means you are not just dragged down the wind, but you can max out to a fair 50 degree of side wind. So you will actually follow an angle, not just back/tail wind, says Joni P. (valppaus.com) one of the pioneers in packsailing from Finland.
Packrafts will capture bigger lakes and bays by that. Speed is no longer bound to run along moving water.
Uncoil the batten and connect clips on the mounting harness to the front grap loops of your packraft or directly your backpack attached. A continuous sheet (or steering line) allows the paddler to easily control the sail while keeping the paddle in their hands for bracing and steering.
It’s the batten that makes the difference, and without the batten, the sail is just an un-supported rag. The quality in the sail perimeter batten is so high that we offer a lifetime warranty on the sail. In the end it is the batten that is the critical part of the sail, it can bend around a small 360 degree mandrel.
Seams are also glued and triple zig-zag sewn, sail makers construction method proven over the years.
There is also a large window in the center panel of the sail for visibility, made from tough TPU. The design puts the center of force of the sail down low, at about the same level as the paddler, making the boat/sail combination incredibly stable and easy-to-use.
Material: Nylon fabric, large, clear window from TPU. PP rope, thread, Grummets made from plastic. Stiff and sturdy, virtually unbreakable batten, yet easy to coil.
