lugsails

Lugsails are a type of sail that is characterized by a yard that extends beyond the mast, to which the sail is attached. This setup allows for a larger sail area to be carried on a given mast height compared to some other sail types. Lugsails are often seen on traditional sailing vessels, particularly those from Northern Europe and Asia.

The yard of a lugsail is typically suspended from a single point on the mast, often by a parrel or other rigging. The sail itself is usually a four-sided shape, with the head attached to the yard. The tack is secured to the lower part of the mast or the deck, and the clew can be controlled by a sheet. A key feature of the lugsail is its ability to be easily reefed, reducing its area in strong winds. This is often achieved by tying sections of the sail to the yard or by using a second, smaller yard.

Lugsails can be set in various ways. A common configuration is the standing lug, where the yard is fixed at an angle. Another is the dipping lug, where the yard is lowered and brought around the mast to change tacks. This latter method allows for a more efficient tacking maneuver. The simplicity of the lugsail rig, combined with its efficiency and ease of handling, made it a popular choice for fishing boats, cargo vessels, and other working craft for centuries. Its adaptability to different wind conditions and its robust construction contributed to its longevity in sailing history.
