The DSe Hybrid - the first truly “Green” motoryacht in the U.S. - took shape as all the parameters were developed. The goals are:
1. 5 Knots electric cruising speed (Zero Emissions).
2. 7 Knots diesel cruising speed at 5 NM/Gal.
3. Two excellent staterooms with ensuite heads for two couples or a family cruising together.
4. Economy both underway at any speed plus efficient, fuel-free living on the hook.
5. Spacious and comfortable “Great Room.”
6. Roomy and congenial Express-Style Bridge.
7. All the “optional” equipment included as standard to which all current Island Pilot owners have become accustomed.
First came a pair of sleek hulls, their underwater shapes resembling a torpedo. The DSe requires a total of 6 kW to cruise at 6 knots in electric, zero-emissions, mode. (see sea trial results). The superstructure is designed to maximize the horizontal surface for the 6 kW photovoltaic solar array.
In the stern of each hull is a Steyr Motors Parallel Hybrid Propulsion System using a Steyr “Monoblock” 75 HP diesel with an inline 7 kW motor/5kW generator leading to the ZF Saildrive. In the bows are 48 vDC battery banks made up of AGM-style deep cycle batteries from Enersys - a total of 20 kW-hours. In electric mode, the permanent-magnet motors provide silent cruising speeds of up to 6 knots. To run faster (or at night), start the diesels for a cruising speed of 7 knots. When the diesels are running, the motors become generators, supplying a charging current (10 kW total) for the battery arrays. The diesels can be run in neutral (at anchor) in generator mode, each supplying either 2 kW or 5 kW (operator selectable). A pair of 3.6 kW pure sine wave Outback inverters supply the 120 vAC for air conditioning, cooking, entertainment, hot water and outlets.
None of this cutting-edge technology takes away from her comforts — An “Island Queen” on-deck master & an “Island Queen” guest (converts to twin berths), each with ensuite heads and stall showers. The “Great-room” deckhouse has a roomy & efficient galley (complete with the Island Pilot signature refrigerator/freezer). The two settees, high-low table and 26” HDTV and Bose home theater have all been proven in the Island Pilots and actually are enlarged for use here in the DSe Hybrid.
The express-style bridge has wrap-around seating for 8, twin helm chairs (the same sports car seats found in the Island Pilots) and centerline console housing the Garmin 15” GPSMAP 5215, the Steyr LCD touchscreen control panels and the Tecnautic “Fly by Wire” steering, autopilot and engine controls.
The DSe Hybrid measures 39’ 6” x 17’ 0” x 35”
