摘要：	Vessel Repair, a shipyard in Port Arthur, Texas, located on the Sabine-Nech-es Ship Channel, has announced being awarded a patent for the hull of its Pacesetter class of pushboats. The patent is for a new design that is a combination of single- and double-chined hulls, the announcement said."The majority of towboats are constructed with single-chined or double-chined hulls," said Kurt Moerbe, vice president of Vessel Repair, by way of providing a background. "Each have their advantages and disadvantages."Boats with single-chined hulls are cost effective to build, stable, easy to dry-dock and have hulls that resist sliding. However, they do not have an efficient water flow, they are less maneuverable and consume more fuel, he said. Double-chined boats have improved water flow and fuel consumption, but are more costly to build, less stable, harder to dry-dock and have hulls that slide hard when maneuvering.
