Eight man rowing shells in lightweight and super heavyweight configurations have an elongated hull with a bow and stern and a smoothly tapered hull surface therebetween. The hull surfaces have particular cross-sections below the waterline at stations spaced along the hull waterline. Other parameters for both super heavyweight and lightweight hulls are provided such as waterline length, entry and exit angles, maximum beam, maximum draft, and metacentric height. In both configurations, the hull itself may be made of a laminate of a fiber composite skin over a core, such as a carbon fiber/honeycomb laminate, or of natural materials such as wood.

An apparatus for testing different electrical sensors used in machinery includes first, second and third insulated conductors, a grounded connection, a power supply, a low signal detector, a high signal detector, a varying signal detector, and an indicator. The first and second conductors are connectible to sensor under test to respectively conduct ground and supply voltage signals to the sensor. The third conductor is connectible to the sensor under test to conduct an input voltage signal from the sensor to the low, high and varying signal detectors. The low signal detector compares the input voltage signal with a low voltage reference signal. The high signal detector compares the input voltage signal with a high voltage reference signal. The varying signal detector compares the input voltage signal with a positive voltage reference signal. The low, high and varying signal detectors produce output signals of either first or second states which are received by the indicator. In response to any one of the output signals being of the first state, the indicator assumes a first condition indicating that the operation of the sensor under test is satisfactory. In response to all output signals being of the second state, the indicator assumes a second condition indicating that the operation of the sensor under test is unsatisfactory.

A four-man rowing shell comprises an elongated hull made of a laminate of a fiber composite skin and having a pointed bow and stern and a hull surface tapering smoothly to a maximum beam and draft therebetween, the hull surface having a waterline length of at least 41.4 feet, a hull entry angle between about 3.85 and 4.70 degrees, a hull exit angle between about 4.78 and 5.84 degrees, a maximum draft below the waterline of between about 0.525 and 0.56 feet, inclusive, and a maximum beam of between about 1.48 and 1.60 feet, inclusive, when the shell is normally loaded.

An eight-man rowing shell comprises an elongated hull made of a laminate of a fiber composite skin and having a pointed bow and stern and a hull surface tapering smoothly to a maximum beam and draft therebetween, the hull surface having a waterline length of at least 56.0 feet, a hull entry angle between about 3.8 and 4.3 degrees, a hull exit angle between about 5.0 and 5.5 degrees, a maximum draft below the waterline of between about 0.595 and 0.610 feet, inclusive, and a maximum beam of between about 1.82 and 1.85 feet, inclusive, when the shell is normally loaded.
