The well designed combination of different materials allows a weight reduction without any loss of stability. Due to different stretching characteristics of the individual materials, we can precisely define each sail profile under stress and guarantee you stable sail performance for a long time.

Mostly used on the flatwater range due to a lot of surface in the boom area. The longest batten of the sail starts below the boom area, crosses the boom line and ends above the clew. The crossing batten does stabilize the profile, which is extremely important in that area. Like that the sail is more effective in acceleration and pumping and has a more stable pressure point.

The alternate positioning of the battens on the back and the front of the sail leads to a more equalized tension- and weight distribution. This arrangement will provide you with the exact same sail feeling, independent of the direction you are riding.

The aerodynamically optimized mast sleeve, resembles the wing of an airplane and enables maximum power development of your sail. An additional line of kevlar warp laminate in the middle of the mast sleeve is working like an anchor, holding the 3D profile in its defined position. Therefore the center of effort stays always in its place and the sail continuously accelerates!

The Smart Clew Construction is based on the tension specific and precise alignment of different materials. The result is an extremely durable clew area without additional weight. Depending the sail the layout of the materials varies in order to suit the resulting tension lines in order to distribute the force from the clew, towards the Tension Frame into the sail. That helps to create more response, better profile stability and long lasting sail characteristics.

Double Seams provide the most stable connection between panels or different materials. They find use in areas of high material tension and make your sail tough and durable.

Multidirectional X-Ply is used in high stress areas. The thread layout shows a higher density of polyester yarn, thus making the material more resistant than the regular X-Ply. The additional vertical thread direction allows the material to take more tension and force in the critical tension line.

The square ply is based on the same concept as X-ply material. However the threads are aligned in a 90 degree angle and the material offers a higher overall thread density. That allows us to reduce the thickness of the included monofilm to save weight, but ensure durability at the same time.

Through the selected use of kevlar warp laminate, we are able to precisely define the stretch properties of every sail. This leads to more response and a long lasting and stable sail profile. The light and unidirectional kevlar threads show very low stretch, even under highest loads. They are individually positioned in each sail to suit its range of application, leading to long lasting performance and sail characteristics.

Our cambers have outlying rolls which ensure easy positioning on the mast. Once in position, the rolls reduce the friction and allow an easier and softer rotation of the sail. We offer four different types of camber depending on the position they are used in the sail.

The choice of the right batten setup with the correct batten type is a crucial point to influence and optimize the sail profile. In the BOW we use up to 4 different tube batten diameters in order to create the aerodynamically perfect profile. Light 9 and 11mm tubes in the top area to control the twist and save weight, combined with slightly stiffer 14 and 16 mm tubes in the boom area to withstand higher sail pressures and secure the profile stability.
