Modern dredging equipment may be divided into four main classes. The grab dredge is used where the amount of excavation is relatively small. It consists of one or more grab buckets, operated by cranes mounted on a vessel or barge or sometimes on the shore. Each bucket has jaws that are hinged together.
This boat is a 1976 18 ft. Landau ALL WELDED jon boat. It is 76 inches at the top and 58 inches at the bottom. It is very stable in all water conditions and the extra wide bottom drafts very little water so you can get in the shallows where the ducks want to be. It has a removable boat seat with a swivel chair. The wide open floor plan is perfect for hunting or fishing.
Traditional lap pools are about 10 feet wide, though widths between 8 and 10 feet are common. (In competition pools, swim lanes are 2.5 meters wide, or about 8.2 feet.) You don't want to go too narrow with a lap pool. When people swim, their bodies generate wave action, and those waves reflect off the sides of the pool.
