TOEIC Link Vocabulary Cluster — Anchor Chain and Windlass Survey: The Report Lexicon for Ranging, Gauging, and Passing a Ship's Cable

An anchor is only as reliable as the chain behind it and the machine that pays it out, so at fixed intervals a ship's cable is dragged out link by link across the pier, measured for wear, and either renewed or passed for another period — while the windlass that heaves it is stripped, tested, and certified to hold under load. That operation, the anchor chain and windlass survey, is one of the more measurement-dense inspections in class maintenance: every link has a nominal diameter, a measured diameter, and a wear percentage that decides its fate, and the windlass brake has a holding capacity that must be demonstrated, not assumed. Because the survey is so procedural and so number-driven, it recurs as a source domain for TOEIC Link marine and technical reading passages. The workflow is fixed: the crew ranges the cable ashore, the surveyor gauges representative links, wear is calculated against the wastage allowance, the windlass and its brake are tested, and a renewal or pass is recorded shot by shot. That sequence generates a stable cluster of roughly forty terms. A candidate who owns the cluster reads the passage at native speed; a candidate who does not stalls on the load-bearing nouns and loses the passage's argument.

This guide isolates the cluster, groups it by survey stage, and maps each term to its native collocation and register tier, because TOEIC Link scores writing as well as reading. Pair it with the writing vocabulary precision and collocation discipline guide for the skill of choosing the exact term, and with the writing tone and register control guide for matching a term to the formality of the survey report around it.

Why this cluster rewards study

A cable-ranging passage assumes its vocabulary the way a draft-survey or bunker-survey passage does. If a reader decodes ranging, gauging, and wastage allowance one word at a time, the attention the module intends for the inferential questions is consumed by decoding. Learning the cluster converts those stalls to zero and frees the reader to answer what the passage actually asks — why a link that looked sound was still condemned, what the wear figure is measured against, and where in the cable the disputed shot lies.

Stage 1 — Ranging the cable and reading it out

The survey opens by getting the whole cable out of the locker and laid out so it can be read shot by shot.

Anchor cable — the full length of chain connecting the anchor to the ship; the object of the survey. Collocation: the cable is ranged ashore; the cable is paid out from the locker.
Ranging — dragging the cable out onto the pier or dock so every link is accessible. Collocation: the cable is ranged along the quay; ranging is completed before gauging.
Shot or shackle length — a standard unit length of chain (typically 27.5 m) joined by a connecting link. Collocation: the cable is marked shot by shot; wear is recorded per shot.
Chain locker — the compartment the cable stows in when not deployed. Collocation: the cable is stowed in the locker; the locker is inspected when empty.
Cable marking — the paint or wire turns that identify each shot to the crew. Collocation: markings are renewed during the survey; a shot is identified by its marking.

Stage 2 — Gauging the links and finding the wear

This stage carries the cluster's most discriminating vocabulary — how each link is measured and how the wear figure is derived.

Gauging — measuring the diameter of a link with a caliper to determine wear. Collocation: representative links are gauged; the diameter is gauged at the crown.
Nominal diameter — the original design diameter of the link bar. Collocation: wear is measured against the nominal diameter.
Mean diameter — the average of measured diameters used to compute wear. Collocation: the mean diameter is calculated from two readings.
Wastage or wear-down — the loss of material from the link, expressed as a percentage of nominal. Collocation: wastage is recorded as a percentage; wear exceeds the allowance.
Wastage allowance — the permitted percentage loss before the link or shot must be renewed. Collocation: the shot is renewed when wastage exceeds the allowance.

Stage 3 — The link, the joining hardware, and its condition

The report separates a link that is merely worn from one that is defective, and this is where the classification gets contested.

Stud — the crossbar cast into each link to keep it from deforming; its integrity is checked. Collocation: the stud is checked for looseness; a dislodged stud condemns the link.
Crown — the curved end of the link where wear concentrates against its neighbour. Collocation: the crown is gauged; wear is found at the crown.
Connecting link or Kenter shackle — the detachable joining piece between two shots. Collocation: the shackle is dismantled for inspection; the connecting link is renewed.
Swivel — the fitting that lets the cable rotate to shed turns near the anchor. Collocation: the swivel is freed off; a seized swivel is reported.
Cracked link — a link with a fracture, condemning it regardless of wear. Collocation: a cracked link is condemned; the crack is confirmed by magnetic particle testing.

Stage 4 — The windlass, the brake, and the load test

The survey closes on the machine that heaves the cable and the brake that must hold it against the full pull of the anchor.

Windlass — the deck machine that hauls in and pays out the cable. Collocation: the windlass is overhauled; the windlass is run under test.
Wildcat or cable lifter — the toothed drum whose pockets engage the links. Collocation: the wildcat engages the links; a worn wildcat slips under load.
Brake-holding capacity — the load the windlass brake must hold with the drum disengaged. Collocation: the brake-holding capacity is demonstrated; the brake holds the rated load.
Bow stopper or chain stopper — the device that takes the cable's load off the windlass when riding at anchor. Collocation: the stopper is engaged at anchor; load is transferred to the stopper.
Renewal shot — a shot condemned by wear or defect and replaced. Collocation: a shot is renewed; the renewal is recorded against the shot number.

How to drill the cluster

Read the cluster once as a sequence — from ranging the cable, through gauging and the wastage figure, across the link and its hardware, to the windlass and its brake test — so the terms attach to the workflow rather than to a list. Then read a genuine anchor-and-cable survey report and mark every term above; the collocations do the retention, because the cable is ranged ashore and the shot is renewed when wastage exceeds the allowance are the phrasings a TOEIC Link passage reuses without gloss. For the writing module, practice restating a condemnation finding in one precise sentence — the exact-term discipline in the writing vocabulary precision and collocation discipline guide — and match its formality to the report frame in the writing tone and register control guide. Own the forty terms and a cable-ranging passage stops being a decoding exercise and becomes what the module intended: a test of whether you can follow an argument about why a link that measured within tolerance was still pulled from service.
