Greenline 33 Review, Specs and the Story Behind Greenline Yachts

The boat that put Greenline Yachts on the map

Anyone researching Greenline Yachts ends up at the 33 sooner or later, because this is the model that created the brand. Slovenian studio J&J Design, run by brothers Jernej and Japec Jakopin and credited by Motor Boat and Yachting with more than 300 designs for 55 builders, launched Greenline in 2008 and built the boats at its Seaway yard. The pitch was simple and, at the time, unusual: a roomy 10-meter family cruiser with a diesel-electric hybrid option, a solar roof and a slippery hull, sold at a price that undercut most conventional rivals.

It worked. Motor Boats Monthly judged the hybrid among the best-value 30-footers on the market at under 100,000 pounds, and the boat won Best Wheelhouse and Walkaround at the 2011 Motor Boat Awards. By the end of production in early 2023, about 550 had been delivered to owners in 28 countries, which J&J Design claimed made it the world's best-selling 10-meter boat.

The company had a bumpy ride. In 2015 a Slovenian court filed an insolvency petition on behalf of Seaway, but Greenline continued, and by the end of the 33's run the brand belonged to SVP Yachts, which still builds the larger models.

A sailboat-derived hull under a motor cruiser

Greenline calls the shape a superdisplacement hull, and the reason it behaves so differently from a typical planing cruiser is its origin. Motor Boats Monthly reported that Seaway adapted one of its sailboat hulls to get the low-drag underwater shape needed for the small electric motor to move the boat at all. The result is long, fine and easily driven, happiest at 6 to 10 knots, and it will push past that with enough diesel horsepower without ever behaving like a true planing boat.

That sailboat DNA brings a gentle roll in any beam sea, which twin wing keels reduce without eliminating. One British owner who logged 925 engine hours over 12 years, including a Channel crossing and the French canals, simply stayed in port once waves passed about 1.5 meters. The 33 is CE category B for eight people: a capable coastal boat, not a passagemaker.

Construction is conservative: a solid polyester hull laminate, foam-cored decks and vacuum infusion. Motor Boat and Yachting saw no core delamination risk in the hull and judged the interior finish basic but durable.

What 'hybrid' really meant on a Greenline 33

Here is the detail buyers miss: not every Greenline 33 Hybrid is actually a hybrid. The hull side said hybrid on most boats, but the electric motor and lithium battery bank were options. In 2010 the 7 kW motor and 48-volt, 240 Ah lithium polymer pack added 23,500 pounds in the UK, plus another 7,673 pounds for the roof solar panels, and plenty of buyers skipped them. Motor Boat and Yachting described many boats as hybrid ready rather than hybrid equipped.

On a true hybrid, the electric motor sits on the shaft line and doubles as a generator when the diesel runs. Early boats paired it with a Volkswagen Marine diesel; Power and Motoryacht's 2013 US spec listed a 150 hp VW/CMD TDI coupled to a 7 kW Iskra electric motor with a 5 kW generator. Greenline claimed about 20 nautical miles at 4 knots on batteries alone, and the solar roof could supposedly sustain about 3.5 knots on the sunniest days. Late boats moved to a Volvo Penta D3-220 with a 14 kW motor and 10 kW generator, up to two 13.3 kWh LiPo packs and 6.5 knots on electric power, while a full-electric version used a 50 kW shaft motor with a 4 kW diesel range extender.

Diesel-only boats used engines from about 60 to 260 hp from Volvo Penta, Volkswagen and Nanni; the last builder spec listed a 250 hp Yanmar 4LV.

• Diesel only: simplest to own, cheapest to buy, still efficient thanks to the hull
• Hybrid: silent marina and canal running, battery-powered house loads, but battery age is critical
• Full electric (late boats): quiet and clean, but range and charging dictate how you cruise

Speed and fuel numbers from tests and owners

Do not buy a Greenline 33 expecting sportscruiser pace. Motor Boat and Yachting's original test boat, with a 165 hp VW diesel, reached 13.3 knots and 5.5 knots on electric power, with suggested cruising speeds of 7 knots slow and 10 knots fast and a quoted diesel range of 431 miles. Power and Motoryacht listed 11 knots cruise and 14 knots top for the US-spec 150 hp hybrid, and the late 250 hp Yanmar boats were rated at 18 knots maximum.

The more useful numbers come from owners. The British couple mentioned above chose a 60 hp Nanni for economy and kept a detailed log: across 925 engine hours their average burn was 5.7 liters per hour, roughly 1.5 US gallons per hour, at a cruise of about 8 knots with 10 knots flat out. Motor Boat and Yachting used that figure to estimate up to 491 nautical miles at 7 knots. Few 33-foot cruisers with an enclosed saloon and full galley come anywhere near that frugality.

Aft galley, one-level living and a single big cabin

The layout is the 33's real selling point. There is no step between the bathing platform and the helm, and the galley sits aft where it serves both saloon and cockpit. A sliding door and a large rear window that hinges up to roof level turn the galley into a servery, and a worktop extension flips down to form a small cockpit bar. One owner described it as opening up like an ice cream shop, which is exactly the right picture.

Forward of the galley, two large settees face a two-leaf dining table. The helm bench flips over to become part of the starboard settee, which is clever but leaves no bolster and no room to stand and drive. Visibility through the saloon glass is excellent, though only two small side windows and the center windscreen open.

Below, a single forward cabin uses scissor-action berths that work as a vee or slide together into a king-size island double, with hanging lockers on each side. The one head has doors to both the cabin and the companionway, so it serves as en suite or day head. Some boats added a small second cabin or bunk; owners who skipped it gained storage, and testers noted it was cramped anyway. Realistically this is a couple's boat that can sleep four using the saloon.

On deck, near-waist-high bulwarks make line handling safe, the transom folds down on an electric winch to form a swim platform, and there is a boarding gate on the starboard side only.

Ownership costs, solar power and service

Running a Greenline 33 is cheap by powerboat standards. Fuel is a rounding error for most owners, and a 10-meter boat can be trucked between cruising grounds relatively economically. In the US, budget roughly $8,000 to $20,000 a year for a slip, insurance, haul-out, bottom paint, engine service and the occasional systems repair, with the higher end for a full hybrid that needs specialist attention.

The solar roof is useful even on a diesel-only boat because it keeps house batteries topped up for refrigeration and lighting; late boats had six panels totaling 1.8 kW as standard. On a hybrid, Motor Boat and Yachting advises confirming the lithium pack still holds a decent charge and lining up an engineer qualified to maintain the system, since older packs will not match the original 20-mile electric range.

Engine access is the one daily irritation: the motor lives under a hatch beneath the dining table, so checks mean moving cushions and folding the table over.

Finding a Greenline 33 for sale in the US

Most of the roughly 550 boats were sold in Europe, so the US pool of Greenline 33s for sale is thin and many listings are overseas. Current European asking prices run from about EUR 123,000 to 169,000 for 2010 to 2015 boats, about EUR 160,000 for a 2018 and EUR 180,000 to 249,000 for 2020 to 2023 hulls. In US dollars that suggests roughly $125,000 to $290,000 for most of the fleet before shipping, duty and recommissioning.

Value retention has been strong because nothing quite replaced the 33 at its price. Prioritize a documented hybrid with healthy batteries, or a well-serviced diesel-only boat priced accordingly, and check whether the optional stern thruster was fitted; with one engine and high topsides the 33 needs practice in a crosswind.
