H-Drive system

The hybrid "H-Drive" system was launched in 2009 with the Greenline 33, the first production boat with this system. With constant technological development we now have the 3rd generation of the H-Drive available.

Apart from the convenience of having mains 230VAC at all times, the other advantage of the H-Drive is silent and emission free navigation. The boating community now calls this “Gentleman’s Boating”. Why? Because only the Greenline Hybrid allows you to navigate without disturbing your neighbours at the anchorage or in the marina.

The H-Drive provides a range of up to 20 nautical miles at approximately 4-5 knots on a full charge, more than enough for a typical and relaxed day on the water.

How it works

The protected H-Drive connects the 4 modes of operation with full integration and simplicity.
The control system provides a simple interface to the user, via a single switch (Diesel/Electric).

Benefits

Simple maintenance
Ease of use
Use of electric energy for propulsion: the running cost of electric boating is 10 times lower than burning diesel fuel
Smoke, noise and vibration eliminated
230/120V AC power system at any time, either at the dock or at sea

Charging and driving modes

Shore Power Charging Mode

Greenline Yachts - Shower power charging mode

At the dock, the boat is plugged into the 230V (120 V) AC shore power supply. The battery pack is under charge and the inverter provides AC power to run home appliances such as fridge, TVs, etc.

Diesel Drive Charging Mode

The diesel engine propels the boat and drives the generator, which recharges the battery pack. A full charge takes only 2-2.5 hours on diesel mode.

At anchor mode: Charging with Solar Panels

The solar roof array charges the batteries, which provide AC power supply for the appliances via an inverter. If the level of battery charge drops below a set value, the diesel engine should be switched on in order to drive the generator and charge the battery pack via generator(s). The propeller is disengaged (the gearbox is in neutral). This is the anchor charge mode.

Electric Drive Propulsion

Greenline Yachts - Electric propulsion mode

In the electric drive mode the boat propulsion is provided by the electric motor using the power from the Lithium battery. This zero-emission mode is used to sail in and out of a marina or anchorage with no noise, no smoke and an insignificant wake. At 4-5 knots a fully charged battery pack provides a range of up to 20 miles.
