Ewol announces EnergyMatic propeller

Ewol has announced its new patent pending EnergyMatic propeller, which has an automatic return to the feathered variable-pitch mechanism and electric charging.

EnergyMatic is a propeller for sailing yachts, specifically to facilitate putting the propeller (blades) in the feathered variable-pitch and is designed to provide minimal resistance under sail on boats with hydraulic or electric propulsion.

According to Ewol, thanks to its internal automatic return to the feathered variable-pitch mechanism, EnergyMatic positions itself with minimal resistance even without the need to stop the shaft. This means that it is no longer necessary to switch off the engine and engage reverse gear to significantly increase sailing speed, with a range of 0.5 to 1.5 knots.

EnergyMatic’s ‘charging’ position is designed to turn the propulsion line into a hydro-generator. Ewol says this is an essential feature for boats with 100 per cent electric or hybrid propulsion or with an alternator connected to the shaft; these boats will therefore be able to recharge their batteries simply by sailing in ‘recharge’ mode, by letting the propeller itself function as an electric turbine and generate a considerable amount of energy while sailing.

EnergyMatic is a lightweight, high-performance, high-tech propeller that allows the pitch to be altered to increase motor cruising speed and aids manoeuvrability during mooring manoeuvres. Like the other Ewol propellers, it is made entirely of stainless steel to maximise strength, resistance to galvanic corrosion and product reliability over time.

The new product was offically presented at the Cannes Yachting Festival and will be showcased at the Newport International Boat Show – EWOL stand B18.
