Q&A – Frequently Asked Questions
Q: Which length should I choose?
A: Calculate the difference between the mast length and the sail's luff: the 32 cm covers small differences, while the 46 cm offers more range and allows you to use the same mast with multiple sails.
Q: Is it compatible with my base?
A: Yes, if the base has an Euro Pin (Universal Pin) attachment, the most widely used standard. It is not compatible with US Cup bases.
Q: Is it suitable for an SDM mast?
A: No, it is an RDM extension. For standard-diameter masts, an SDM extension is required.
Q: Why choose aluminum instead of carbon?
A: It costs less, is extremely robust, and in the event of overload, it bends instead of breaking suddenly; carbon is lighter.
Q: How do I maintain it?
A: Rinse the pins and pulleys with fresh water after use at sea and periodically check the top of the downhaul.
