What is a mast bend curve?

A mast bend curve describes how a mast flexes under load. Unifiber offers three profiles: Constant Curve (CC), Constant FL (Flex Low), and Constant FH (Flex High). Matching your mast's bend curve to your sail's design ensures optimal shape, stability, and performance.

Can I use Unifiber masts with other sail brands?

Yes. Unifiber masts are compatible with most major sail brands. Our Mast Selector uses 10+ years of compatibility data to recommend the correct bend curve match for your specific sail brand and model.

What is the difference between SDM and RDM masts?

SDM (Standard Diameter Mast) has ~48mm base diameter and delivers direct power for freeride and racing. RDM (Reduced Diameter Mast) has ~36mm diameter with thicker walls, offering better control and durability for wave and freestyle sailing.

How much carbon content do I need?

Carbon content affects weight, response, and price. Essentials C50 offers durability at great value. HD C75 balances performance and durability. Elite C100 provides maximum lightness and response for demanding riders.
