| 摘要 |
A buoyant line or rope made from two or more strands of natural or synthetic fibers, with the fibers in one or more of the strands being arranged (e.g., by being spun or "laid") around a buoyant core. The relative buoyancy of the line may be increased or decreased by changing the number of strands having a buoyant core or by changing the diameter of the buoyant cores.
