This is the photo-journal of a trip on an Excitecat 810 power catamaran from
Connecticut down to Key West in late 2005 - 1600 nautical miles covered in a
total of 125 hours under way.
Excitecat 810 used in this trip was Sound Catamarans' demonstration model,
equipped with twin Yanmar 160HP engines and a full cruising package, including
GPS, autopilot, chartplotters and full instrumentation at both inside and
As with most power catamarans, the
810 offers exceptional comfort, stability, manageability and economy.
what is truly unique about the Excitecat is the generous amount of interior
accommodation in a boat of only 26' - including two private
galley with fridge, stove and
sink, and a roomy head and shower compartment.
In addition to the full
instrumentation, live-aboard conditions were made entirely comfortable by the
additional amenities of electric flush head,
electric windlass, inverter, hot water heater...
Navigation and Data Collection
From Connecticut to Annapolis, MD, I
ran Nobeltec's Visual Navigation Suite electronic charting program on my laptop
computer with data feed from a handheld GPS, in addition to the on-board
Raymarine E-80 chartplotters. From Annapolis to Key West, I used only the the boat's
Raymarine systems with Navionics Gold cartridges..
While using Nobeltec on my laptop, I
recorded data every 15 minutes
(including boat speed) and I downloaded this information to show
graphically how the boat performed in offshore and open water conditions (see
Boat Speed and Fuel Consumption
With the consistent and regular record
of GPS boat speed from Nobeltec,
it's possible to graph the actual speed over ground during passages and
this is presented here for the Connecticut to Annapolis section of the trip
(click to enlarge):
For the remainder of the trip, average speed for the day was calculated by
tracking the boat's course on the Raymarine E-80 chartplotters and dividing by
hours under way and this is
recorded at the end of each day's run in the Journal.
Overall, the figures for the trip
