Quick Summary

The term "liner" can refer to a ship belonging to a regular line or an airplane belonging to an airline. In the context of fishing, a "hook-and-liner" is a boat used for fishing with hook and line, such as a tuna clipper.12

Fishing vessels are designed based on the methods they employ. "Liners" in commercial fishing encompass various vessels that use hooks and lines, either manually or mechanically. These include:34

  • Longliners: Larger vessels with hooks attached to a rope, often featuring automatic systems for baiting and removing fish.4
  • Pole-and-line vessels: Use lines on poles or rods, requiring a large crew and clear deck edges for maximum fishing area.5
  • Handliners: Typically small, open or decked boats operating inshore.6

Other fishing vessels, like lift-netters, use nets lowered over the side, attracted by lights. Vessel design prioritizes efficiency, safety, and reduced operating costs, with materials like steel, wood, and fiberglass commonly used.3
