A-class masts



Our masts designed for A-class are made in two basic groups:

1. More rigid towards the trailing edge and relatively soft at the sides

2. Softer towards the trailing edge and more rigid at the sides.

The basic measurement method of masts is two-dimensional bending of the top under 20kg weight. Based on measurement of the flexibility and deflection, any sail is individually designed and added to every mast produced by us. This policy guarantees extrtemely good results. Any set made by us is always easily trimmed, according to current weathercast. Only then, both the turning mast and the sail make one coherent voilure.

Apart from standard masts, we produce them individually in any parameters and flexibility.
