Greenline offers alternative to traditional generators across range

Greenline Yachts is offering extended battery packs and special alternators that can eliminate generators on all its diesel models. The new ‘Responsible Power Pack’ technology, features a combination of bigger battery packages and alternators, enabling lower emissions. All boats in the range will now offer at least 48 hours of silent battery power at anchor or docks, the boatbuilder says.

Greenline says owners can run the entire house (including aircon full blast) and make the most of their home on the sea without the noise, vibration and smell of a generator. Greenline’s model range runs from 39ft to 58ft.

Instead of a generator, Greenline will fit a high-powered alternator that can take power from the engine when it runs to recharge a large lithium battery bank. In this way, the yacht can arrive at its destination with full batteries, ready for days of silent operation at anchor. When energy is used efficiently, the autonomy of the yacht can be extended for days by using solar power to cover hotel loads such as induction cooking and lighting.

“For conventional yachts, eliminating the generator is nothing short of revolutionary,” said Vladimir Zinchenko, owner of Greenline Yachts. “There is barely a yacht on the market in Greenline’s class of length and luxury that is capable of doing this. My mission has always been to further the concept of responsible yachting, and this shift towards using high-powered alternators and batteries will save tonnes of CO2 emissions.”

Case study: Greenline 45

Take the Greenline 45 – the Slovenian yard’s best-selling model. In the past, this yacht has needed an 11kW generator to cover hotel loads, consuming 4 litres of fuel per hour. It often runs constantly in order to power the air conditioning unit, amounting to consumption of nearly 200 litres over a 48-hour period at anchor.

Fitted with the new Responsible Power Pack, it would require nine hours of motoring to fully recharge the 34.2kWh batteries, giving emissions-free power on board for more than 48 hours. To produce its 6kW of power, the alternator places additional load on the engine which does marginally increase fuel consumption for that period. However, when compared side by side, the new system slashes the emissions of covering hotel loads by up to 88 per cent.

“The figures are unequivocal,” said chief commercial officer Luca Raumland. “Our Responsible Power Pack can eliminate a staggering amount of the carbon emissions associated with running a yacht at anchor. By tapping the engine’s spare power when the yacht is under way, we can make non-hybrid models almost as efficient to operate as their hybrid alternatives. In fact, with careful use of the aircon, the solar panels fitted as standard to every yacht can fully replenish the batteries during the day and keep you emissions-free at anchor indefinitely.”
