Вообщем написал об этом на сайт прайда, ответили чтобы не заморачивался, с 34 удлинителем все должно бы нормально.

Question:

I bought a sail NP 10 RS/Slalom MK III 7.0 with a mast X6 460. According to the specification the recommended base for that rig is 2 cm. The shortest NP extension is 34 cm. When I adjust the extension to the recommended size it enters into the mast as far as 42 cm. I know too long an extension can impair the curve of a mast and the performance of a sail.
Can I use the extension of 34 cm for my rig?
Best regards
Dmitry

Solution:


Hi Dmitry,
No Problem to use this extension in your sail. It will not cause any negative effect on its performance.
