Inspection Log

A written record of every line and fitting — the cheapest piece of safety equipment there is.

INSPECT BEFORE LOAD · NEVER EXCEED WLL

Rope, splices and hardware are only as good as their condition. Inspect before every use and retire on evidence.

Overview

An inspection log is a record: what was checked, when, by whom, and what was found. It sounds bureaucratic for a small boat and it is the single most effective safety measure available, because it turns inspection from a habit into a system. A line that has been in service for six seasons and has been inspected each of them can be retired on evidence rather than on guesswork.

What goes in it is simple. Each line and each item of hardware gets an entry with its size, its location, its date of purchase and its history. Each inspection records the date, the findings — chafe, glazing, stiffness, cover damage, corrosion, wear at the bearing point — and the decision: in service, derated, or retired. Retired items are recorded with the reason and then physically destroyed so they cannot return to service.

The value shows up in the discard criteria. Most people retire a line too late, because a line that looks fine is assumed to be fine. A log with a purchase date and a load history makes the decision objective: a line that has taken a serious shock load is retired regardless of appearance, and one that has reached its service interval is inspected closely rather than casually.

Safety notes

  • Record the decision, not just the check. An inspection with no outcome is not an inspection.
  • Retire on evidence: a line that has taken a shock load is out of service regardless of how it looks.
  • Destroy retired items so they cannot be picked up and used again.
  • Record hardware as well as rope — a worn shackle is as much a risk as a chafed line.

Using it well

  • Write the purchase date on the line's whipping or on a tag, so the age travels with the rope.
  • Photograph any damage you find; a picture makes the next inspection faster and the decision clearer.
  • Keep the log with the equipment, not in an office, so it is there when you inspect.
