Measurement of sailbatten pressure (Compression)
- Pressure must be measured with the sailbatten compressed by 10% of its straight length.
- The sailbatten must be measured with the tapered end down so nearly the whole weight is compressing the thin end.
- Measure length of sailbatten
- Multiply length of the sailbatten by 0.9 (This is measurement A).
- Push the sailbatten down until the tape measurer is equal to measurement A, then read the reading on the scale.
- Measure total length of the sailbatten.
- Place the sailbatten on it’s edge on a flat table, marked in units of 1 cm, then compress the batten by 10% of it’s total length and the highest point can now be determinded. (D)
- You can now make a flexpoint (draft) calculation. Sailbatten length is 200 cm. Compressed lenght is 0.9 x 200 cm. = 180 cm. Length AB = 81 Flexpoint (draft) calculation = 81/180 x 100 = 45%
- Draw a line along the compressed sailbatten.
- You now have the bending curve of the sailbatten.
Protection Kote is a very light heatshrink polyester wrapping which totally protects the batten.
Some advantages are:
- 1. It make’s the sailbatten stronger.
2. Smoother, glossier finish.
3. Less chafing on the sail.
4. No splinters in your fingers.
5. When a sailbatten should break it will hold all the pieces together.
Protection Kote is on all sailbattens except Standard battens (30 x 3 ; 15 x 3).
