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.

Four man rowing shells in heavyweight and lightweight 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.

Lightweight four man rowing shell

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.

Four man rowing shell

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.
