The utmost dependability of today's diesel engines is clearly illustrated by the acceptance of single engine installations in commercial fishing vessels, freighters and oceangoing passagemakers that run for weeks on end, hundreds and thousands of miles offshore. The advantages of a single engine design include:
1) the ability to run the shaft inside a protected keel
2) locating the prop where it is protected by a keel and skeg
3) less vibration and noise
4) easier and less costly to maintain
5) more economical to run
6) reduces the initial cost of purchasing a new boat
For these reasons, the majority of the more than 140 full displacement Nordhavns built to date have featured single engine installations. After 15 years of roaming the world's oceans, there has never been a reported incidence of a single engine Nordhavn having a mechanical problem that caused any serious safety concern. The Coastal Pilot 35 has been designed to take advantage of all the benefits of a single engine installation, and it provides a sensible, economical and reliable way to explore the coasts of the world. While the hull design, large rudder and location of the prop all add up to a boat that is easy to maneuver, a 4 hp electric bow thruster, which is standard equipment, adds to the boat's agility. Backing into a tight slip requires nothing more than lining up the stern using the thruster and backing in with the main engine.
Understanding the importance of dependable power, the 35 Coastal Pilot's engine room is an engineering masterpiece. Standard power features the highly reliable, 370 hp Yanmar turbocharged diesel engine which is mounted on centerline with two 295 gallon fuel tanks outboard. A fuel supply reservoir is located forward along with the dual fuel/water separator system that allows one to change the filter while running. Primary access to the engine room is through a hinged door with viewing port near the head bulkhead, and all key maintenance areas of the power plant, including the stuffing box, are within easy reach. Additional access is available through a large hatch in the pilothouse sole. There is plenty of light to work with, as both 12V dome lights and 120V florescent fixtures are used, and there is abundant room for servicing the engine and all mechanical systems. The bilge areas are finished with gelcoat, and all surfaces are covered by perforated aluminum sheeting painted white. Keeping this engine room looking new will be an easy task. There is ample room for an optional 6kW or 8 kW generator. The lazarette is cavernous and includes the hydraulic steering and hot water heater. Air conditioning compressors, heater furnaces, a watermaker, etc. can all be installed and still it allows for abundant storage. The Coastal Pilot can be set up as a very basic, simply equipped passagemaker, or it can be fitted out with all of today's modern conveniences including a washer/dryer, trash compactor and more.
The performance characteristics of the Coastal Pilot 35 reveals a very versatile vessel. Running at a very quiet 2000 rpm, the Yanmar 370 pushes her at 8 knots, burning less than 5 gallons per hour and giving her a range of just under 1,000 nautical miles. At 2750 rpm, the boat exceeds 10 knots, burning about 12 gph and providing a range of 500 nm. This two-digit speed has proven to be a very popular cruising speed for many coastal cruisers. When it's time to push the throttle forward, the 35 will run at between 12 and 15 knots, making it possible to outrun that storm or get into port before dark.
