With all the talk of 3 Batten vs 4 Batten.
And whats better, 4 or 5, in bigger sails.
NORTH SAILS ontinues to lead the way with the new SWITCH BATTEN concept.To put it simply.
Any sail 5.0 and smaller, will be 4 or 3 batten compatible.
Its just a matter of removing the Batten #2 to give more low-end and early planning. Then replacing it when the wind picks up.

Same goes for 5.3m and up sails. Run the sail as 4 Batten in the lighter winds, for early planning and power and then add the 5th when it cranks in, for stability and better power distribution.

Check it out, in the final of PWA Tenerife.
