Loss of or Damage to Property: A Master's First-Hour Response Guide

P&I loss-prevention material is consistent on one point: what a Master does in the first hour after discovering lost or damaged cargo or third-party property shapes whether the resulting claim is defensible or not — far more than anything that happens afterwards in a formal investigation.

Preserve Evidence Immediately, Not Eventually

Photographs, witness statements, retained samples, and timestamped log entries taken in the first hours after discovery are consistently what P&I clubs point to as the difference between a claim the company can actually defend and one it can't. Waiting until "there's time to do it properly" is how this evidence gets lost — take it rough and immediate over polished and delayed.

Document Before Cargo Is Released, Not After

A Master's letter of protest, or a notation of damage on the mate's receipt or bill of lading, needs to happen before the cargo leaves the ship's custody — not as a follow-up once it's already been discharged and released. This is a common timing failure: the damage is real and documented internally, but the formal notation that actually protects the ship's position never gets made before release.
