The technology for our sail battens
Material
Our battens are pultruded with unidirectional E-glass fibres and a special epoxy resin matrix, which creates an optimum ratio of stiffness to weight.
Our battens are also finished with a topcoat finish for a smooth surface.
Finish
Protection Kote is applied to the tapered battens and in the standard colour glossy black. Other colours are also available on request.
Protection Kote is a very light shrink sleeve, which fully protects the batten and has the following advantages:
1. Smooth and tightly finished surface
2. Less friction on the sailcloth
3. No annoying splinters in the fingers
Batten pressure
The pressure of the batten is measured when 10% of the length is pressed vertically on a scale. The batten must be measured with the profiled side downwards.
Bending curve, maximum profile depth
By laying the batten flat and compressing the length of the batten by 10%, a bulge is created at the front of the batten, or bending curve. The position of this bulge in relation to the length (- 10%) of the batten is expressed as a percentage and is the profile depth of the batten.
Example: Batten length is 200cm. Compressed length is 0.9 x 200cm = 180cm. Length from the front of the batten to the position of the bulge = 81cm. Profile depth calculation = 81/180 x 100 = 45%
Dynaflex sail battens are guaranteed against defects in the material and finishing. We are not responsible for defects caused by inappropriate use and/or use for another purpose than sail battens. Our liability is at all times limited to the amount paid for the delivered product. By ordering our sail battens, you automatically accept our conditions.
