Fuel management is critical to the operation of my 28' deep vee sportfisherman powered by twin 350 C.I.D. gas engines. An average offshore trip typically covers 120 nautical miles running as speeds ranging from six knots trolling to cruising. Over the years, many fishing days were cut short by the uncertainty of remaining useable fuel.
Two years ago, I purchased the FloScan Cruisemaster 5500 which immediately became one of the most important instruments onboard. It has consistently provided consumption accuracy within one-percent. Upon compilation of speed and consumption data at all levels of operation, it became apparent that significant economies could be achieved through minor adjustments in cruising speed. In the case of my vessel, reducing the cruising RPM's by 150 produced a four gallon per hour total fuel savings with a loss of speed of approximately one-half knot.
The fuel savings in each of the two seasons of operation exceeded the purchase price of the instrument. In addition, the peace of mind associated with never again guessing at the ability to return to port with a margin of safety is reassuring.
My only regret is that I chose the entry level model which lacks the Tach, synchronizer and NMEA interface.
Congratulations on a spectacular product. |
