Ascan Mast Extension Big Wheel US-SDM

FAQ

What is a mast extension used for in windsurfing?

A mast extension is inserted between the mast and the mast base to increase the sail height and thus the leverage of the rig. It is useful if the sail does not fit directly on the existing mast or if the desired trim requires additional length.

For which masts is the Ascan Big Wheel US-SDM suitable?

This mast extension has a US mount and is therefore designed for SDM masts (Standard Diameter Mast). Make sure that your mast has the correct diameter so that the extension fits properly.

What lengths are available for the Ascan Big Wheel US-SDM?

The Ascan Big Wheel US-SDM mast extension is available in two lengths: 15 cm and 30 cm. This allows you to choose the right size for your setup.

How does the Ascan Big Wheel adjustment system work?

The extension features an adjustment system in 2.5 cm increments. This allows the effective length to be finely adjusted and optimally adapted to the sail, mast base, and trim.

What does the Big Wheel designation mean for this mast extension?

Big Wheel refers to the three large brass rollers in the pulley block. They ensure low-friction, smooth sheet running and distribute the load evenly across the pulley – an advantage in strong winds and during longer sessions.

Is the Ascan Big Wheel US-SDM compatible with all mast bases?

The mast extension is designed for the US mount at the top end. Which mast base can be used at the bottom depends on its mount. Check before purchase whether your mast base is compatible with the extension.

Who would benefit from a mast extension with a large pulley block?

An extension with a large pulley block like the Big Wheel is worth it for anyone who values easy trimming, smooth sheet running, and robust mechanics – from ambitious beginners to experienced recreational windsurfers.
