Pacific
Odyssey Yacht
Engine Room
The engine compartment of the Pacific Odyssey is easily
accessed by 6 separate hatches. The main engines twin
3208 turbocharged Cat diesels rated at 375 HP each. Each engine has a large Racor
filter and dual FloScan pulsation
dampers with
precision flow meters. At sea power is
provided by an 8KW Northern Lights Diesel Generator.
A 4000 watt inverter is also available to convert power
form the dual battery bank to 110 AC.
The inverter can run the microwave and coffee maker without
starting the diesel generator.
There is a dual Jabsco pump fresh water system with large
accumulator tank and a separate fresh water Jabsco wash down
pump that can be
used to clean the anchor as it is retrieved. Spare engine oil, hydraulic fluid,
antifreeze, etc
is all neatly stored in the engine room. The Pacific
Odyssey contains a complete set of tools and a large inventory of
spare parts including belts, pump impellors, etc.

FloScan Installation and Technology
Two pulsation
dampers and flow sensors are required for each engine to monitor
diesel supply and return lines. All units are mounted to outboard of the engines.

FloScan :With the rising cost of
diesel fuel, now as high as $1.25 per liter in Canada, a logical approach would
be to invest a bit of time and money into figuring out just how to minimize or
at least reduce fuel costs. I noted several comments from individuals that chartered
the Pacific Odyssey that they had no idea filling up the diesel tanks would
cost that much for their one-week vacation cruise.
As the vessel owner I already provided RPM
vs. speed curves, but this was also easy to obtain from the onboard, state-of-the-art
integrated Raymarine Navigation System.
I know I would be doing vessel charters a big favor by providing
accurate fuel consumption data to minimize the “Sticker-Shock” when filling up
at a fuel dock. With the installed FloScan system, I now had the technology to
provide these answers.
Fuel Consumption
Calibration:
I ran all the calibration tests in calm water, vessel fully loaded with minimal
wind in a protected channel. I started at 1500 RPM and continued every 100 RPM
until 2600 RPM. At each RPM interval I allowed sufficient time, approximately 1
minute, for the GPS and fuel readings to stabilize. I started the first calibration run at 1500 RPM and went to 2600
RPM then immediately repeated the test in the reverse direction starting at
2600 RPM and then reducing speed to 1500 RPM.
I did this to give me an idea of repeatability.
Fuel Consumption Charts: A number of different Speed vs RPM vs Fuel Consumption tables are provided for the Pacific Odyssey. This will greatly assisted the charter skipper to minimize fuel consumption.
