What About Drag?

Sub-Hull Speed Performance

There is a minor speed reduction of roughly 0.1 knots when charging (varies by boat displacement)

Virtually Unnoticeable at Hull Speed

Once you hit hull speed, the effect of the hydrogenerator becomes virtually undetectable

Reduced Drag When Disconnected

When your batteries are topped off or the system is disconnected, drag is further reduced for crisp sailing

Real-World Proof: The Remoran Hydro Generator in Action

The Remoran Wave 3GS is a beautifully made piece of kit. It simply sits on the back of the boat and delivers power to our batteries mile after mile. It’s quiet, it’s reliable, and we’ve done 31,000 miles without touching it -apart from once clearing some polyprop from the propeller. Zero maintenance. The support we got from Remoran and Advance Yacht Systems couldn’t be faulted. Installation went without a hitch, and the unit’s been completely reliable.

— Mike Hutchinson - Remoran Wave 3

Dependable power generation

  • Day and night — keeps working when solar panels can’t

  • On every point of sail — unlike wind turbines, it still charges when sailing downwind

  • More independence — reduces engine use and helps you stay off-grid longer

Reliable power, less maintenance, and fewer hours on your engine.

Accessories

Remoran Protection Relay - PR-02
£244.00

The Remoran PR-02 helps protect the Remoran Charger from overvoltage if you exceed the maximum speed of your Remoran Hydrogenerator.

The PR-02 includes lugs for easy mounting, screw terminals for connecting the generator (AC) cable and a fixed 50 cm long (AC) cable for connecting to the charger.

Compatible with the Remoran Wave 3GS and 3GD.

Remoran Long Rail Kit
from £116.00

The Long Rail Kit allows the outboard unit of Remoran Wave 3 to be fitted onto the rail without the turbine reaching the water. The unit can be held securely at the top position, until you decide to lower it into the water, which can be done under moderate speed (5 knots or less).

Also includes mounting accessories.

Compatible with the Remoran Wave 3GS and 3GD.

Remoran EasyLift
£739.00

The Remoran EasyLift lets you raise and lower your Remoran hydrogenerator from the deck at speeds of up to 10 knots, so you don't need to reach down to the blue handles. The EasyLift system is particularly beneficial for classic boats that lack swimming platforms.

The EasyLift system allow you to adjust the angle of the Wave 3 from 0 to 40 degrees, with an extra 5 to 10 degrees at the transom using the Wave 3’s adjustment feature. Weeds can often be removed just by changing the angle so they slide off.

Compatible with the Remoran Wave 3GS and 3GD.

Remoran Ocean Kit
£213.14

The Ocean Kit is designed for rough seas and high speeds, where the angle adjustment bracket on your Remoran hydrogenerator might need some extra support.

The kit includes:

  • Angle Lock

  • Spare Turbine

  • Spare Anode

The angle lock should be used in the following conditions:

  • Speeds between 10-15 knots; and

  • Angle set between 10 and 40 degrees

Compatible with the Remoran Wave 3GS and 3GD.

FAQs

  • The sailing speed reduction is roughly 0.1 knots during charging. This applies when the boat is moving at less than hull speed, and is dependent on many other factors such as boat size and speed.

    Once hull speed is reached, the hydrogenerator's effect won't be noticeable. Also once the batteries are full or the generator cable has been disconnected the sailing speed reduction will be less than at full charging mode.

  • Yes, the hydrogenator can be kept in the water while motoring.

    The charger will detect the higher voltage from the motor's generator, assuming they are connected to the same battery, and go into idle mode while motoring. The Remoran Wave 3 will resume charging once sailing continues.

  • No. The sturdy metal-on-metal construction can handle the stresses of backing up.


  • No. The Remoran Charger 300W is a smart charger and uses algorithms optimized for Lead-Acid (incl. AGM) or Lithium batteries. The charger algorithm ensures your batteries will be optimally charged without any adverse effects. Once the battery is full, the charger will go into idle or floating mode.
