Greenline has put a lot of faith and effort into its hybrid propulsion system and the introduction of the Greenline 48 at the Newport International Boat Show in September 2014 reinforces the company’s commitment. This model bridges the gap between Seaway Yachts’ Greenline fleet (up to 50 feet LOA) and its Ocean Class (up to 88 feet).
Designed by J&J Design (brothers Jernej and Japec Jakopin) of Slovenia and built by Seaway in the same country, this newest of the Greenline hybrids is the first to have a flying bridge.
Wrapped inside this vessel’s handsome exterior is a logical and spacious arrangement plan, which features a single-level sole from the transom to the helm. A very large tinted-glass partition separates the saloon from the afterdeck, and it has a bifold door on the portside section. The starboard-side panel splits horizontally, the top half swinging up and the bottom half retracting vertically into the cabin sole. The backsplash on the after section of the C-shaped galley folds down to form a serving bar that reaches into the cockpit. A bench seat and small table at the transom have room for two to enjoy meals.
Windows, windows, windows—aboard the Greenline 48, folks can see out when they’re seated at the dinette and lounge. The light wood of the furniture, off-white fabric, and overhead give the interior a casual but elegant ambience.
Belowdecks, the Greenline 48’s symmetrical arrangement plan has two mirror-image en suite guest staterooms amidships.
Neither head has a separate shower stall. Each of these cabins has a single hanging locker, twin berths, and a large portlight.
The master stateroom in the bow is large, comfortable and has two hanging lockers. The head is on the starboard side against the bulkhead, and the shower stall is opposite.
The 48’s lightweight, resin-infused laminate, combined with her easily driven hull shape and horizontal propeller shafts, contribute to her excellent fuel economy—900 miles at 7 knots under diesel power.
The Greenline’s hybrid power package has three modes. At the dock, plugging into shore power charges the batteries while the inverters run the 220-volt appliances. In electric-drive mode, the batteries supply all the power to propel the boat. A fully charged battery pack gives her a range of about 20 miles. Additional charging comes from the solar panels on the forward section of the superstructure.
As we explored the environs of Boston Harbor, winds averaging about 15 knots, played among the many islands of this historical area, and we found ourselves in beam seas of more than 2 feet in one place, only to have them on the nose or from an after quarter as we changed course. The 48 rolled predictably, but not violently, in the short, steep, beam seas. She steered accurately in following seas and authoritatively plowed her way through the head seas. The most astonishing of her characteristics was the quiet, all the way to maximum speed under diesel power. When we switched to electric, which requires shutting down the diesels and then pushing a button, we could scarcely tell that she was running.
It was pure solitude onboard, almost like being on a, gasp, sailboat. And only slightly worse for the environment too. Not bad for a power boat. Not bad at all.
