Seaway’s Greenline 33: Eco-Friendly Cruising in Style

Seaway Yachts, the Prius of yachts, is taking the U.S. by storm. Seaway’s Greenline 33 is their latest hybrid yacht, capable of running on diesel, electric and/or solar power, and using an innovative central control device. The yachts are built in Slovenia, and provide a surprising amount of style and comfort alongside their eco-friendly profile.

Seaway has built 330 of the Greenline 33 to date, “making them the largest boat builder of 33-34-foot boats.

The Greenline 33’s hybrid technology “is a parallel hybrid (diesel/electric) propulsion system coupled to a Lithium battery bank and a photovoltaic array on the cabin roof,” according to Seaway. Chuck Laughlin, owner of St. Barts Yachts in Charleston, S.C., and the newest U.S. dealer for the Greenline 33, said Seaway has built 330 of the Greenline 33 to date, “making them the largest boat builder of 33-34-foot boats.”

you can use over 80% of the battery power, and still recharge solely via solar power

The boat uses a Lithium polymer 48-volt battery measuring 3’ x 1.5’ x 6” and weighing 165 pounds. It transitions from diesel to electric and back with the flip of a switch. Although expensive, the Lithium battery has a 10-year life expectancy. When the diesel is running, the electric motor becomes a generator that recharges the battery in four hours. Alternatively, solar panels on the cabin roof can continuously recharge the battery, and Laughlin claims that you can use over 80% of the battery power, and still recharge solely via solar power. It takes a full day of sun to fully recharge the battery.

Under electric power, the Greenline 33 has a cruising range of 20 nautical miles at 4 knots for 5 hours. The cruising range of the 132-gallon diesel tank, at 14 knots, is 200 nautical miles.  Reducing your speed by half will give you a 700 nautical miles.

The cruising range of the 132-gallon diesel tank, at 14 knots, is 200 nautical miles.  Reducing your speed by half will give you a 700 nautical miles. “Theoretically,” says Laughlin, “you could cruise from Charleston to the Caribbean without using a drop of diesel.” The boat is also very easy to operate, equipped with bow and stern thrusters and a stabilizer.

The innovation doesn’t stop with the hybrid technology. The boat is equipped with a GreenPad, developed from iPad technology, that uses a central communication device, the GreenBox, as a sort of private WiFi.  It allows all the systems information to be communicated to your GreenPad, alerting you to any problems. The complete owner’s manual is contained on the device, and every piece of equipment has a QR code. Scan the code and the page for that part appears on the GreenPad.

Having just received his first model in late November, Laughlin explained that “this is the third generation of fine tuning the boat. They have been very successful…we haven’t found anything wrong with the model we have.”

Closed up at the dock, the Greenline 33 looks like any other boat…until you board and lower the transom, extending the deck another 2.5 feet. The aft wall of the galley is hinged, allowing the top half to swing up to the overhead deck, transforming the galley and saloon into a more open air space.

Laughlin envisions being at anchor watching the kids racing dinghies. “Between races, they can pull right up to the deck, have something to eat and drink, and be on their way to the next race.” It is a great family space. The boat can be fitted with one or two cabins, with a queen-sized bed fitted in the bow suite and bunk beds in the second cabin. The entire finish is simple yet sophisticated.

Also available is a 40-foot model, identical to the layout of the 33 but with two engines, two batteries and two 5-blade props. Next on the horizon is a 48-foot Greenline, making its U.S.  debut at the 2014 Miami International Boat Show.

When Seaway first started the Greenline, Garth Hitchens, owner of Annapolis Yacht Sales in Maryland, was the only dealer in the U.S.  A close friend of Laughlin, Hitchens encouraged him to also become a dealer. Now, Greenline North America is setting up a dealer network. The southeast U.S. has Annapolis Yacht Sales, St. Barts, and Denison Yacht Sales in Florida. Seaway ships the Greenline 33 straight from Slovenia to Charleston, and St. Barts’ territory includes the Carolinas, Georgia and Tennessee.

Seaway is a global leader in 40 countries in milling, engineering, tooling, composite technologies and prototyping for composite-related building. The company, located in south central Europe, has also designed hulls for Beneteau and Sea Ray through its design firm, J&J Design.  They now build their own brands including the Greenline Hybrid, Ocean Class hybrid yachts, Skagen motor yachts and Shipman carbon sailboats.
