Rather than guess what speed you should run your boat, it is important to develop real-world numbers of the speed and burn consumption your boat reaches at various engine speeds in open water. Depending on how your boat is equipped and loaded, and the propeller(s) you have, it is a straightforward process to develop a speed/fuel burn performance curve that will identify the sweet spot for running your boat at cruising speed.
Along the way of determining this ideal speed envelope, you will also get an sixth sense of when the hull and engine is in harmony as she glides through the water with maximum efficiency and reasonable fuel burn. This is a satisfying project every boat owner should create for his or her boat.
It’s been a long time coming but we now see tangible progress emerging to reduce our dependence on fossil fuel. If the U.S. Navy can prove that it works, isn’t it about time the concept of the modern cruising boat includes hybrid forms of propulsion?
