Fuel Efficiency Guide

Protect the marine environment by running your boat efficiently - be OceanSMART

Engine Operation - Pull'er back

  • Speed is the singular most important factor to influence fuel consumption. The underlying principles are worth going over.
  • Energy is expended in making surface waves alongside and behind the boat.
  • The effort expended in creating these waves is known as the wave-making resistance.
  • As speed increases, the amount of effort spent making waves increases disproportionately to the increase in speed.
  • At higher speeds the engine itself may not be operating at its most efficient, particularly at approaching the maximum RPM.
  • As a result significant fuel savings can be had through speed reduction.
  • Improving fuel efficiency

Regular Maintenance - Keep'in it oiled

  • Run in a new or reconditioned engine carefully.
  • Follow the engine manufacturer's maintenance programme.
  • Change oil, filters and separators regularly
  • Make daily inspections of the shaft, bearings, couplings and stuffing box for increased vibrations, dirty filters and sufficient lube.
  • Entrust complicated mechanical work to a qualified mechanic.

Fishing - Lose the drag

  • Reduce gear drag
  • Consider gear monitoring during operations.
  • A more efficient gear may increase productivity and catch rates, while reducing energy costs.
  • Audit your system to discover areas where you can reduce drag and fuel consumption.

Over 60% of all resistance comes from the drag on the netting while fishing.  Ways to reduce drag:

  • Reduce the amount of netting surface
  • Increase mesh sizes
  • Decrease twine sizes
  • Introduce super fibres
  • Consider a net monitor to help audit your fishing operations.
