what is a yachts rope called

A yacht “rope” is usually called a line. More specifically, it may be a sheet when it controls a sail, a halyard when it raises a sail, or a dockline/mooring line when tying the boat up.

Quick terms

• Rope : the raw material.
• Line : rope with a job on a boat.
• Sheet : a line that trims a sail.
• Halyard : a line that hoists a sail.
• Dockline / mooring line : a line used to secure the yacht.

Simple rule

If you want the short answer for everyday use: on a yacht, people usually say line , not rope.
