Maximizing Vessel Efficiency...

Maximum Efficiency means finding the best possible match between the propeller and the boat, engine, transmission combination. There are a few things you can do to make sure your vessel is maximizing efficiency:

   Make sure the boat is able to achieve the wide-open-throttle RPM at your desired vessel weight. Diesel engines are designed to operate at an optimal speed. In order to achieve that speed, the propellers must allow the engines to operate at their wide-open-throttle. In some cases the engines do not turn up to the rated RPM because the propellers may be the wrong size. This causes the engines to run slower and become overloaded. Overloading causes incomplete combustion that, in turn, causes excessive carbon build up (among other problems) leading to premature wear and ultimate failure. Other factors that decrease RPM and overload the engine are increasing the vessel weight, higher water temperatures going through the vessel’s heat exchangers, increased ambient air temperatures, dirty air and fuel filters, and a dirty hull.

2. 		We Picked up 1.5 knots, which equates to 12-15% fuel savings per year. The results are beyond what I expected. Captain Mike Keating Spirit of Adventure

   Do an accurate sea trial at the desired speeds, for example low/high cruise and wide-open-throttle. Write down the speed and the RPM information and provide these figures along with your Assessment Form. With this information, Propeller Solutions can provide suggestions to increase speed and reduce fuel consumption.
3. Vibration and Cavitation are two common propeller-related problems that can be major reasons for not obtaining performance. Propeller Solutions can help by either altering your existing propeller or by providing the correct design to reduce or eliminate propeller induced vibration or cavitation.
4. Become involved in the early stages of your hull design and re-powers so you can develop problem-solving solutions.
