MV Moby Duck’s Specifications
Fundamentals
MV Moby Duck is a George Buehler designed Diesel Duck 462. “46” denotes the length and the “2” denotes that it was built by Seahorse Marine.
Moby Duck is a steel flybridge motorsailer that represents the safest and “greenest” ocean crossing trawler on the market under 50 feet. It combines the narrow fuel efficient seaworthy deep keel hull typical of a sailboat with the comfort and convenience of a trawler. With it’s watertight dogged exterior doors, thick pilothouse windows, deep keel and small pilothouse (excellent a/b ratio) the boat is self righting. The boat has 5 watertight compartments in addition to the fuel tanks lining the bottom of the hull. This effectively gives it a double steel bottom. It has a flushdeck design, meaning no deep cockpit or side decks like the typical trawler sedan style design i.e. Nordhavn, Selene, and Kadey Krogen to catch water. This is a much more seaworthy design.
The boat can be completely powered by renewable resources. It’s efficient 24 volt systems (refrigeration, water maker, electronics etc.) and ALL standard LED lighting can be completely powered by the wind generator and solar panels. The ketch rig and fully feathering underwater pitch adjustable 5 blade prop allow the boat to use the sails as a “get home” device, for stabilization and for significant fuel reduction when motorsailing. Based on the recent edition of “Passagemaking Under Power”, the bible of the industry, the Duck is the most fuel efficient trawler on the market. If you do not want to mess with the sails, the boat has a 4045 John Deere continously duty rated 120hp engine with 2000 gallons of fuel and a complete paravane rig for underway and at anchor stabilization. A Dickinson diesel burning furnace provides heat.
The boat has a 9kw Northern Lights generator to run the washer and dryer, dive compressor, for extra battery charging capacity and to run the air conditioning systems.
