Abstract
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.

A rowing shell comprising an elongated hull having a pointed bow and stern and a smoothly tapered hull surface therebetween, said hull surface having a waterline length of at least about 51.5 feet and the following cross-section areas, in square feet, below the waterline at stations spaced along the hull waterline when the shell is normally loaded at about 1,658 lbs.:
- ______________________________________ station 0 0.000 +/- 5% station 0.5 0.066 +/- 5% station 1 0.185 +/- 5% station 2 0.452 +/- 5% station 3 0.649 +/- 5% station 4 0.747 +/- 5% station 5 0.772 +/- 5% station 6 0.748 +/- 5% station 7 0.653 +/- 5% station 8 0.458 +/- 5% station 9 0.200 +/- 5% station 9.5 0.077 +/- 5% station 10 0.000 +/- 5% ______________________________________
- wherein station 0 signifies the fore-most point of the hull, and station 10 signifies the aft-most point of the hull, along the waterline, and wherein a unit station spacing is one-tenth of the waterline length.
An eight-man rowing shell comprising an elongated hull having a pointed bow and stern and a hull surface tapering smoothly to a maximum beam and draft therebetween, said hull surface having a waterline length of at least about 57 feet when the shell is normally loaded at about 2,014 lbs., an entry angle as measured at the fore-most point of the hull along the waterline of between about 3.6 and 4.0 degrees, inclusive, and an exit angle as measured at the aft-most point of the hull along the waterline of between about 4.05 and 4.95 degrees, inclusive.
An eight-man rowing shell comprising an elongated hull having a pointed bow and stern and a hull surface tapering smoothly to a maximum beam and draft therebetween, said hull surface having a waterline length of at least 57.1 feet, a maximum draft below said waterline of between about 0.614 and 0.629 feet, inclusive, and a maximum beam of between about 1.90 and 1.92 feet, inclusive, when the shell is normally loaded at about 2,014 lbs.
