As of 2015, Grumman makes aluminum rowboats, including the Seneca and Otisco lines, and aluminum motorboats, including the Oneida and Owasco lines. These boats are constructed from marine-grade aluminum alloy with heavy-gauge aluminum on the keel and upper rim. The fasteners and bow eyes are made from stainless steel.
All Grumman boats feature two-piece hulls with watertight welded seams, rib-free interiors and built-in cup holders. Grumman rowboats feature bench seating and sockets for oarlocks.
In addition to compartments for engines and fuel tanks, Grumman motorboats, such as the Oneida Side Console, offer other amenities, including upholstered swivel seating with under-seat storage, plush carpet and textured vinyl flooring options, and added storage compartments. Grumman motorboats also feature dash consoles with steering, switches and speedometers, all shielded by a tinted windscreen.
Aluminum boats are a good option for fishers, hunters and boating enthusiasts looking for an inexpensive, easy-to-transport boat. The relatively small aluminum boats can navigate freshwater streams and rivers that are inaccessible to larger boats. Due to their light weight and small size, boaters can secure aluminum boats on top of utility vehicles or tow them with a light trailer. Aluminum boats range from 8 to 24 feet in length and hold up to eight passengers.
