MEASUREMENT OF BATTENS

BATTEN PRESSURE (Compression)

1. Pressure must be measured with batten compressed by 10% of its straight length.
2. The batten must be measured with the tapered end down so nearly the whole weight is compressing the thin end.
3. Measure length of batten
4. Multiply length of batten by 0.9 (This is measurement A).
5. Push the batten down until the tape measurer is equal to measurement A, then read the reading on the scale.

BATTENCURVE, MAXIMUM FLEXPOINT OR DRAFT

1. Measure total length of batten.
2. Place the batten 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)
3. You can now make a flexpoint (draft) calculation.
   Batten 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%
4. Draw a line along the compressed batten.
   You now have the bending curve of the batten.

PROTECTION KOTE

Protection Kote is a very light heatshrink polyester wrapping which totally protects the batten.

Some advantages are:

1. It make's the batten stronger.
2. Smoother, glossier finish.
3. Less chafing on the sail.
4. No splinters in your fingers.
5. When a batten should break it will hold all the pieces together.

Protection Kote is on all battens except Standard Battens (30 x 3 ; 15 x 3).
