Key Technologies - Greenline Hybrid System

Every Greenline has solar panels and AC power onboard at all times as standard with the upgrade of additional solar panels on the T-top available on the new Greenline 45 Fly and the Greenline 48 Fly.

Solar Roof

Regardless of whether you choose the Hybrid-Drive system or a standard diesel drive, your Greenline can collect and store power from the sun, utilizing highly efficient solar panels on the hardtop thereby producing plenty of electricity to power all systems including home appliances with 230V or 120V AC power to make your living onboard as pleasant and convenient as possible.

The Photo-Voltaic (PV) panels on the hardtop keep the batteries fully charged and provide additional energy for the boat’s Hybrid-Drive or Electric-Drive system.

6 PV panels with forced air cooling deliver up to 1.8kW per hour of electric power in daylight conditions.

As a result, they are capable of supplying constant power to on-board 230V or 120V consumers such as refrigerator, air conditioning and entertainment systems, thus removing the need for a generator or shore power.

Benefits:

Green energy production
Cost and emission-free sailing
No maintenance

Lithium Batteries

Lithium batteries have been around for a while, powering your smartphones, laptop computers and other gadgets that represent a large part of our lives today. With the wider adoption of electric vehicles in recent years technology has progressed, and we are proud of the fact that starting in 2009 Greenline Yachts has been pioneering the use of Lithium Polimer batteries for heavier consumers such as electric propulsion for vessel navigating.

Greenline Yachts utilize the best lithium (Li-Po) battery technology available: a 11.5 kWh on Greenline 33 and Greenline 39 and up to 40kWh on the Greenline 40, 45, and 48 Fly.

Rated for thousands of charge cycles, these batteries outperform lead battery types by a factor of five to six.

Very powerful, lightweight (7 times lighter, 1/3 of normal battery size) and maintenancefree, these batteries are the ultimate for your hybrid boat with a life expectancy of over 10 years.

Benefits:

Low maintenance
Ease of use
More time spent out on the water, whether cruising or at anchor
Estimated 10 years life expectancy
Lightweight and compact

Hybrid Hull Design

The Hybrid hull incorporates some of the properties of a modern sailing boat hull that moves through the water with the least amount of drag and exceeds the theoretical speed of the hull that is defined by the length of the waterline.

Hybrid hull enables cruising at higher speeds while still maintaining optimal consumption and stability at lower cruising speeds. The power of the engines defines the cruising speed without having to compromise the safety, stability or consumption levels of your Greenline.

The reduced energy requirement means less running cost and less refueling stops. The hulls are efficient throughout their speed range, bringing unbeatable mileage and range of over 700 nautical miles at a speed of 7 knots. The electric drive mode will not only allow to cruising in complete silence at speeds of up to 6 knots but also offer a range of up to 20 nautical miles before the diesel motor is required.

The Superdisplacement hull also offers optimum performance in all sea conditions. The Greenline offers comfort and safety when underway and manages any kind of sea situation with ease, needing only minor corrections at the helm.

The twin sacrificial stabilizers have three functions: they deliver roll stability, tracking stability, and protect the drive and rudder. The structure of the boat will not be affected if the stabilizers get damaged. The fins can be replaced quickly and inexpensively.

Benefits:

Comfortable, safe ride
Easy maneuvering
Low running costs

Hybrid Drive System

Greenline Yachts collect, store and use electrical energy from the sun, from the shore connection or from the main engine driven generator. With a solar array and a Hybrid drive electric unit, the yacht is a mobile power station providing a constant supply of AC power (230 or 120 VAC) on board.

The hybrid drive system (protected) consists of the following elements:

A single switch that lets you choose between two drive modes: diesel or electric.
A modern, low emission diesel engine.
A fully electronically managed and maintenance-free electric motor/generator (eM/G). The generator charges the batteries and supplies power to onboard consumers.
A hydraulic clutch between the diesel engine and the electric motor/generator.
A 3 kW inverter/charger delivers a 230 V AC power supply throughout the boat at all times and charges the battery in the shore power mode.
A 1.4 kW solar array delivers green electric power to the batteries during the daytime. At low speed, no cost and emission-free sailing is possible.
A 12 kWh Lithium battery pack is seven times lighter and one-third of lead battery size and rated at thousands of cycles. They have a life expectancy of 10 years and represent the best choice for a hybrid boat.

Consumption Control System

Complete control and monitoring of consumed energy and charging of the batteries from various sources such as alternators, solar panels or generators is available on your smartphone or tablet using mobile application via WiFi connectivity.

Benefits:

Simple maintenance
Ease of use
Use of electric energy for propulsion: running costs of electric boating is 10 times less than burning diesel fuel, even disregarding solar energy
Eliminating smoke and noise
230 (120) VAC power system

A weekend with a Greenline 39…

We calculated how much power we consume spending a typical summer day at anchor. The simple sheet below is applied to a Greenline 39 with standard battery pack as we wanted to make sure the level of comfort is at the highest possible level for you and your family while you spend time on the water without noise, vibrations or diesel exhaust.
