My Flashcards

Definition

Meaning

A rope, line, or tackle used on a sailing vessel to pull down a sail, spar, or yard, typically to control its shape or to lower it.

In broader nautical contexts, any system or line designed to apply downward tension. In technical rigging, it can refer to a control line for tensioning the luff of a sail.

Linguistics

Semantic Notes

A highly specific term from sailing and rigging. Its meaning is almost entirely literal and functional, with no common figurative use. It denotes a part of a mechanical system.

Dialectal Variation

Examples

By CEFR Level

B1
  • The sailor pulled the downhaul to flatten the sail.
  • Look for the blue rope; that's the downhaul.
B2
  • Before the gust hit, he quickly tightened the mainsail downhaul to depower the rig.
  • The downhaul system on this dinghy uses a 4:1 pulley for easier adjustment.
C1
  • Optimal performance requires fine-tuning the downhaul in conjunction with the outhaul and backstay tension.
  • The failure of the composite downhaul block led to an uncontrollable draft position in the genoa.

Learning

Memory Aids

Mnemonic

Think: It HAULs something DOWN. A DOWNHAUL pulls a sail DOWN, while a HALYARD (sounds like 'haul yard') pulls it UP.

Conceptual Metaphor

N/A. The term is almost purely literal and functional.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid direct translation like "низкая тяга". It is a specific nautical term best translated as "фал, оттягивающий парус вниз" or the borrowed "даунхол" in specialised contexts.
  • Do not confuse with general terms for rope or cable (трос, канат).

Common Mistakes

  • Misspelling as 'downhall' or 'downall'.
  • Using it as a verb (e.g., 'to downhaul the sail' is non-standard; the correct verb is 'to tension the downhaul' or 'to pull on the downhaul').
  • Confusing it with a 'sheet' (which controls the angle of the sail, not its downward tension).

FAQ

Frequently Asked Questions

No, it is a very low-frequency, specialised term used almost exclusively in sailing and nautical contexts.

No, it is strictly a noun. The action is described as 'tensioning the downhaul' or 'pulling on the downhaul'.

A cunningham is a specific type of downhaul that tensions the luff of a sail by pulling on a grommet near the tack. All cunninghams are downhauls, but not all downhauls are cunninghams.

Not all, but most modern sailing boats designed for performance will have one or more downhauls for sail control. Simple boats might not.
