Q&A/Frequently Asked Questions

What is the difference between the 32 and the 46?
The 32 covers sails with shorter luff and freeride/freerace set-ups. The 46 offers more room for extension for sails with long luff or for those who want flexibility over multiple sizes.
Is it compatible with RDM shafts?
No. This model is SDM. For RDM shafts you need a dedicated RDM extension .
What top should I use for downhaul?
Compatible with ropes from 3.8-4.0 mm; recommended Dyneema 4.0 mm for best glide and durability.
Is the 8:1 hoist really lighter to arm?
Yes: with 3 pulleys and a 8:1 ratio do you achieve the required tensions with less effort and greater fine-tuning accuracy.
Do you need special maintenance?
Rinse with fresh water after use, periodically check cima and pulleys, check the U-Pin button and apply light anti-corrosion spray to metal parts.
Can I adjust the collar with gloves?
Yes. The collar "Slide & Lock" is designed for wide grip and movement open-and-slide, comfortable even with gloves or cold hands.
