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.
