![]() Noise is stress, both for the occupants of the boat and those within hearing range of its operation. These launches has been created for those who think otherwise. There are some people who consider noise a fine thing and create exhaust systems that maximize sound, presumably to impress others. Motor boats have always carried with them the burden of noise. Four cycle technology tends to be superior to two cycle in fuel use, in reducing pollutants, and sound levels, although at this writing (fall 2005) two cycle technology is improving. In the HB 26, 50 horsepower 4 cycle engines have been used. In the HB 21, 25 horsepower 4 cycle engines have been used. Modest horsepower is enough for moderate speed yet small enough to be efficient. Expense of operation (both in purchase price and fuel cost) increases with speed. Power is needed for speed, but speed has a largely negative effect on recreation as it contributes to increased danger and noise both for the occupants of the boat and other people within its sphere of influence. It is our opinion that 68 horsepower (which is the average used by the North American boater) is excessive for recreational needs. We believe these new launches capture what was lost. In these new developments, the soft, sweet, loping ride of the early Hand designed boats was left behind. As the V-bottom concept evolved and more powerful motors became available, other designers introduced wider, faster (but less seakindly) boats. They will, however, knife through the water at well over displacement speeds. The hulls that Hand developed do not skip along on the surface of the water like fully planing hulls. In truth, their high speed can’t be maintained when the going gets rough. The presumed safety of fast planing boats comes from an assumption that one can reach shelter quickly when the weather deteriorates. These features have been abandoned by the modern outboard runabout which drags its wide or deep-V transom at the slow speeds dictated by crowded conditions or rough water. Moderate beam and a narrow transom give efficiency at low and medium speeds. Hand’s V-bottomed craft had a high easy entry for meeting the waves and moderate beam flowing to a narrow transom sitting at the water’s surface. It should be highly efficient in its use of fuel Hand’s successful work has been taken, and blended with modern power technology to create a new design while always keeping the following principles in mind:Ģ. The hull shape was developed to contend with the short steep seas and stiff breezes of Buzzard’s Bay, Hand’s home waters.
