Among the most fundamental of issues with the concept of a motor-sailer is the commonly held notion that such a vessel must be 50% motor boat and 50% sail boat, implying that the vessel will be only half as good at each task. Emphasis on Sail: A motor-sailer in its ideal form will be 100% sailing vessel, and 100% power vessel. When it is desired to motor most of the time then one can simply use the engine, assuming it is of adequate capacity and there is enough fuel for true passagemaking. With an uncompromised motor-sailor such as this, the boat will also have been designed to function supremely well as a sail boat. It turns out this is not so difficult to achieve, since the requirements for moving through the water efficiently at what is essentially sailing speed are not much different in a true displacement power vessel than in a sailing vessel. Naturally there are optimizations for a motor-sailer that will be powering most of the time. One of the first and most obvious choices will be to provide a comfortable pilothouse rather than the open cockpit of a sailing vessel. The design may be given a higher bow for the inevitable times spent powering into the weather. Freeboard, within reason, is to be desired. However, excess freeboard provides windage, weight, and vulnerable structure up high. structure that cannot be reefed when the weather kicks up. Broad beam is often equated with comfort. This is decidedly not so. Excess beam makes a vessel's motion more harsh with higher rolling accelerations. Excess beam also increases the overall resistance per ton. There must be sufficient beam for good sail carrying power, but no more. Emphasis on Power: Certainly one can create a motor-sailer that has a greater emphasis on power. One can for example design a motor vessel with a good hull form for both powering and sailing, with a "powerboat-like" layout, and with a modest "get-home" sail rig. This combination will offer the simplicity, silence and joy of sailing when the wind favors, in addition to the peace of mind that comes with knowing that a mechanical failure will not jeopardize the safety of the voyage.
