Sonar UHM Carbon Mast 2026

The UHM73 has our shortest chord length – 100mm – this minimises the lateral surface, reducing drag and increasing manoeuvrability. This in turn will give you greater glide, more efficient pumping, and quicker turns. The UHM73 favours disciplines without wind power - prone surf, pump and downwind.
