Aperture B (APB) Feathering Propeller

The Aperture B offers the increased performance of a larger diameter propeller but with the convenience of a small hub which can be fitted to more yachts.

Designed for larger cruising yachts, the first APB model was fitted in late 1992 and has been a cornerstone in Hydralign’s production ever since. To date, we have only recently replaced APB Model after more than twenty years of service, and it was still functioning! A sturdy prop with great performance.

The prop can be counter bored for nut to suit a shorter taper if required.

Can be set up for right hand or left hand rotation
