Greenline 39 Performance Review

Electric Mode Stats

Greenline 39 Hybrid Performance in Electric Only Mode

How fast is the Greenline 39 in electric mode?

The Greenline 39 performance in electric mode delivers quiet, displacement cruising:

Tested configuration:

• 6G Hybrid system
• 2 x 11kWh batteries in factory test (22kWh total, 20kWh usable)
• Optional 33kWh upgrade available
• 7,800kg displacement during test
• 2 persons onboard
• Flat water, zero wind

• 1.7 knots at 0.9 kW
• 3.0 knots at 1.6 kW
• 4.0 knots at 2.9 kW
• 4.7 knots at 4.9 kW
• 5.5 knots at 7.9 kW
• 6.3 knots at 12 kW
• 6.8 knots at 18.2 kW

Top electric speed is approximately 6.8 depending on load and conditions.

This is true hybrid yacht performance, silent, smooth and generator-free.

How far can the Greenline 39 travel in electric mode?

With the optional 33kWh bank (30kWh usable):

• 3 knots: 56.3 nautical miles
• 4 knots: 41.4 nautical miles
• 4.7 knots: 28.8 nautical miles
• 5.5 knots: 20.9 nautical miles
• 6.3 knots: 15.8 nautical miles
• 6.8 knots: 11.2 nautical miles

22kWh vs 33kWh Battery Setup

Which Greenline 39 Hybrid Configuration Is Right for You?

Battery capacity is the key variable influencing Greenline 39 performance in electric mode.
The Greenline 39 can have 22kWh lithium bank with approximately 20kWh usable after reserve or the optional upgrade increases capacity to 33kWh, with around 30kWh usable.

The propulsion system remains identical, but usable range increases by roughly 40 to 50 percent across most speed bands. For owners wanting extended electric cruising capability, the larger bank significantly expands operating flexibility without changing how the boat drives.

What Does That Mean in Real World Cruising?

The 22kWh setup is ideal for owners who primarily use electric mode for:
• Marina approaches
• Short harbour runs
• Silent anchor departures
• Regeneration support while cruising in diesel mode

The 33kWh bank, however, begins to open up genuine electric passage making in protected waters. At 3 to 4 knots, extended harbour or river cruising becomes very realistic.
Importantly, battery capacity does not change Greenline 39 fuel consumption in diesel mode. What it changes is how often you rely on diesel in the first place.

For owners leaning into the full potential of Greenline 39 hybrid performance, the larger bank enhances flexibility, quiet operation and independence from shore power.

What Does Greenline 39 Performance Feel Like in Electric Mode?

On paper, the numbers are impressive. But the real story of Greenline 39 performance in electric mode is how it feels.

At 4 to 6 knots, there is no vibration, no engine note building in the background, no need to raise your voice to be heard. For harbour cruising, early morning departures or sunset returns to anchor, the experience is fundamentally different to a traditional diesel yacht.

The opening helm door, sliding sunroofs and natural ventilation combine with the electric drivetrain to create a calm, almost surreal atmosphere. It transforms the boat from a mechanical machine into something far more connected to the environment.

This is where Greenline 39 hybrid performance truly separates itself from conventional diesel vs hybrid yacht comparisons. It is not just about efficiency. It is about experience.

As Rowan McMahon, Eyachts Sales Manager, explains during testing:

“When you’re in electric mode, the loudest thing you hear is the water against the hull. You’re cruising at six knots, talking normally with friends, no one’s raising their voice, and it just feels peaceful. It completely changes the atmosphere onboard. For harbour cruising or river systems, it’s honestly hard to go back to diesel.”

That emotional element is difficult to quantify in a performance chart, but it is central to understanding Greenline 39 performance in real world conditions.

Can the Greenline 39 run on electric only?

Yes. Electric mode is ideal for:

• Harbour cruising
• River systems
• Marina approaches
• Quiet anchor departures

For owners prioritising silent operation and low speed cruising, the Greenline 39 hybrid performance is a genuine advantage.

Hybrid Diesel Stats

Greenline 39 Fuel Consumption in Hybrid Configuration (250hp)

While electric mode delivers serenity, hybrid diesel mode is where Greenline 39 performance becomes incredibly versatile.

At displacement speeds between 6 and 9 knots, the boat is operating in its most efficient window. Greenline 39 fuel consumption remains modest, the hull rides level with minimal bow rise, and the hybrid system begins regenerating energy back into the batteries.

This is what makes the system so intelligent.

As the diesel engine pushes the boat forward, the electric motor transitions into generator mode, returning up to 13.9kW back into the lithium bank at mid-range cruising speeds. In effect, you are recharging while travelling.

It is not simply diesel propulsion with an electric add-on. It is a fully integrated system that constantly balances propulsion and regeneration.

This dual character is what separates Greenline 39 hybrid performance from traditional diesel yachts. Owners can leave the marina in silence, cruise efficiently in diesel mode while regenerating power, then return to electric operation when approaching anchor.

Regeneration output:

• 7.4 kW at 1,400 rpm
• Up to 13.9 kW between 1,600 and 2,200 rpm
• 13.8 kW at 2,800 to 3,000 rpm

This dual functionality is what defines Greenline 39 performance compared to conventional diesel yachts.

What is the cruising speed of the Greenline 39 (250hp)?

Cruising speeds sit comfortably between 7 and 10 knots, where efficiency and passage time are well balanced. However, the full performance range is outlined below.

What is the fuel consumption of the Greenline 39 (250hp)?

These verified figures confirm that Greenline 39 fuel consumption remains highly competitive across the rev range.

At true displacement speeds around 6 to 7 knots, fuel burn is exceptionally low for a 39 foot motor yacht. Even into the semi displacement range around 10 to 12 knots, the numbers remain efficient relative to comparable cruisers.

What is the cruising speed of the Greenline 39 (370hp)?

With the upgraded engine, the Greenline 39 comfortably cruises in the 10 to 18 knot range, with significantly higher top-end performance available.

What is the fuel consumption of the Greenline 39 (370hp)?

These figures show that while top-end speed increases significantly, Greenline 39 fuel consumption remains controlled at displacement speeds.

At 7 to 9 knots, fuel burn is still moderate. As speed increases beyond 15 knots, fuel consumption rises progressively, as expected with higher horsepower output.

What is the top speed of the Greenline 39 (370hp)?

The verified top speed in this configuration is approximately 25.2 knots at 3,600 rpm, delivering a noticeably faster cruising profile compared to the 250hp hybrid configuration.

What is the range of the Greenline 39 in diesel-only configuration?

Even at higher cruising speeds, range remains practical for coastal passages. At lower displacement speeds, long-range capability exceeds 1,700 nautical miles, demonstrating the efficiency of the hull design.

Hybrid vs Diesel Greenline 39?

As Rowan puts it:“If you want more top-end speed, the 370 horsepower option gives you that extra punch. You’re looking at around 25 knots flat out, which is strong performance for a 39 foot cruiser. It just depends on how you want to use the boat. The beauty is you can choose.”

That flexibility is ultimately what defines Greenline 39 performance across all configurations.

You can prioritise:

• Silent electric cruising
• Efficient long range diesel passages
• Or higher speed coastal runs

Few yachts in this category offer that level of adaptability without sacrificing efficiency.
