TECHNOLOGY. NEW, BUT SIMPLE.

Through an enormous effort in time and money spent in the development phase of the Greenline hybrid, this state-of-the-art product offers great performance, reliability and user friendliness at an incredible value for money.

Unlike today’s modern cars which still need to burn fuel to produce electricity, the Greenline Hybrid Solar is capable of collecting, storing and using power from the sun, which is a breakthrough in hybrid marine technology. With a 1.3 kW solar roof and the Hybrid drive (5kW generator/7kW electric motor integrated in one unit), the Greenline Hybrid Solar is a mobile power station that provides a constant supply of electric power on board.
In spite of its revolutionary design, the technology used in the Greenline Hybrid Solar is not at all complicated. All the systems are electronically controlled, automatically charging the battery when there is an adequate supply of daylight or when the diesel engine is running



Protected Superdisplacement hull

Benefits:

  • comfortable, safe ride
  • easy manoeuvring
  • low running costs
Besides being efficient, the Superdisplacement hull shows optimum performance in all sea conditions - an important factor in comfort and safety when underway. The Greenline 33 manages any kind of sea situation with ease, needing only minute corrections at the wheel. The twin sacrificial stabilisers are a further advantage of this hull, and have three functions: they deliver roll stability, tracking stability, and protect the drive and rudder. If the stabilisers get damaged, the structure of the boat will not be affected. The fins can be quickly and inexpensively replaced.

Keels, drive protection

Twin protective fixed keels at the aft part of the underbody provide excellent directional stability, especially with following seas. At the same time they provide the anti-roll stabilizing effect and additionally protect the propeller and drive during accidental grounding. The keels are sacrificial: if getting damaged during a grounding they are easily and inexpensively replaced without hampering the structure of the boat.

Propeller is further protected by a stainless steel protection preventing ropes, chains or debris to foul the propeller.

Hybrid drive

A fully electronically managed and maintenance-free system.

Benefits:

  • no maintenance
  • ease of use
  • use of electric energy for propulsion: the running costs of electric boating are10 times less than burning diesel fuel, even disregarding solar energy
  • eliminating smoke and noise
  • 230V AC power system


Comparison of fuel consumption in litres per nautical mile: Greenline 33 in Diesel Mode (speed 7 knots) versus a 33-feet Twin Diesel Engine Powerboat (speed 15 knots)

The user-friendly and reliable hybrid drive system (patent pending) consists of the following elements:

  • a single switch that lets you choose between two drive modes: diesel or electric.
  • a modern 5-cylinder marine diesel engine made by Volkswagen.
  • a fully electronically managed and maintenance-free electric motor/generator (eM/G), which consumes 7 kW in the electric drive mode and provides 5 kW of electrical power when driven by the diesel engine (charging the batteries and supplying power to on-board consumers). The two components are integrated into one unit, thereby saving space and weight. The eM/G is coupled to a ZF gearbox, which drives the propeller.
  • a hydraulic VW clutch between the diesel engine and the electric motor/generator
  • A 3 kW inverter/charger that charges the battery in the shore power mode and delivers a 230 V AC power supply throughout the boat at all times.

Solar roof

The solar roof array keeps the batteries fully charged and provides additional energy for the boat’s electric drive system. No-cost and emission-free sailing is possible at low speed (up to 3,5 knots) where the amount of energy harvested from the sun and the system’s energy consumption are equal, making the Greenline Hybrid a solar sailboat.

Benefits:

  • green energy production
  • cost and emission-free sailing
  • no maintenance

6 standard photovoltaic solar panels with forced air cooling deliver up to 1.3 kW of electric power in daylight conditions. As the solar cells are protected against hail by a 3.2 mm glass shield and are easy to access for cleaning, your solar power station requires only a minimum of maintenance. It is capable of supplying constant power to on-board consumers like the refrigerator and TVs and can recharge the batteries to 80% when exposed to a full day of sunlight.

Lithium battery

Just like your mobile phone or laptop computer, the Greenline Hybrid uses the best lithium battery technology available: a 240 Ah battery array with a permissible discharge of 100%.

Benefits:

  • low maintenance
  • ease of use
  • more time spent out on the water, whether cruising or at anchor
  • estimated 10 years life expectanct
  • lightweight and compact

Rated at thousands of charge cycles, these batteries outperform lead battery types by a factor of five to six. Very powerful, light-weight (7 times lighter, 1/3 of normal battery size) and maintenance-free, these batteries are the best choice for your hybrid boat.
