Hydralign offers racing and cruising yachts maximum performance under power in either forward or reverse with minimum drag under sail. It achieves the optimal operational efficiency through its wide range of easily adjusted blade pitches to suit the shape, weight and engine capacity of each craft.

The Hydralign propeller is feathered by simply stopping shaft rotation. Stopping the engine with clutch engaged for hydraulic gearboxes, or engaging the culch after stopping the motor while moving forward, for engines with a mechanical gearbox. Shifting to forward or reverse gear automatically re-sets the blade pitch for drive.

Operation is robust because of bigger, more functional, gearing mechanisms cleverly housed in a sleek casting which presents minimum resistance.

Hydralign products are made from high quality 2C100 alloy manganese bronze and 316 stainless steel ensuring long life and dependability.

A few advantages of using a feathering propeller is that the propeller is not turning constantly thereby eliminating noise and the continual wear of bearings

The pitch of the blades can be set to any angle adapting it to any sailing craft. A considerable amount of drag will be lost when using a feathering propeller which could be the difference between making a landfall in daylight or darkness.

A 3 Blade propeller is usually recommended for cruising yachts for its efficiency and smoothness of operation. Whereas for the racing yachts 2 blades are preferred, primarily because a 2 blade propeller can be locked in a vertical position and minimise drag where the propeller shaft exits the hull in an angled down position.
