Deck Seamanship & Line Handling Flashcards

What does the term 'bight' refer to when working with lines?

Answer: A loop or curve in a line that does not cross itself

A bight is any curved section of line between the two ends that forms a loop without crossing itself.

When securing a line to a cleat, how many figure-eight turns should be taken before finishing with a locking hitch?

Answer: Two

Two figure-eight turns around a cleat provide sufficient holding power before adding a single locking hitch to complete the belay.

What is a 'preventer' line used for on deck?

Answer: A secondary line rigged to prevent sudden uncontrolled movement of a spar or boom

A preventer is a secondary line rigged to a boom or spar to prevent an accidental jibe or uncontrolled swing.

Which condition most increases the risk of a mooring line parting unexpectedly?

Answer: The line shows heat glazing or melted fibers from previous slipping

Heat glazing reduces a synthetic line's strength significantly and indicates internal fiber damage that can cause sudden parting under load.

When passing a line through a closed chock, what is the correct method?

Answer: Use a messenger line led through the chock first

A light messenger line is rove through the chock first, then used to pull the heavier mooring line through.

What is the safe working load (SWL) relationship to a line's breaking strength typically used aboard ship?

Answer: SWL equals the breaking strength divided by a safety factor of 5 or 6

A safety factor of 5 to 6 is typically applied, so the SWL is the breaking strength divided by 5 or 6 to allow a margin for dynamic loads.

What action should be taken if a running line (under load and moving) is found to be riding over itself on a winch drum?

Answer: Stop the winch immediately and re-spool under controlled tension

An override on a winch drum must be stopped immediately; the jammed turns must be cleared under controlled conditions before operation continues.
