Yacht insurance claim surveys: best practice for damage investigations

How to handle a yacht damage and insurance claim survey — scope, cause-of-loss determination, photo discipline, and the report structure underwriters expect.

Damage and claim surveys are the most technically demanding work a small craft surveyor takes on. The deliverable goes straight to an underwriter, an adjuster, or a court — and the standard of proof is materially higher than for a pre-purchase report. Here's how to handle one without exposure.

Get the instruction right

Before you accept the job, get clarity in writing on:

  • Who instructed you? Underwriter, broker, owner, third party. Affects who you report to.
  • What's the alleged cause of loss? Storm, grounding, fire, collision, theft.
  • What's the scope? Cause of loss only? Cost of repair? Both?
  • What's the timeline? Underwriters often want a preliminary within 48 hours.

Misalignment on these is what creates disputes. A one-page instruction email from the underwriter before you mobilise is non-negotiable.

On-site discipline

A damage survey is a forensic exercise. Two rules:

1. Photograph before you touch anything. Wide-angle establishing shots first, then closer detail. If you move a tarp or a fender, photograph what it was covering and where it ended up. 2. Bag and label any debris the owner is keeping. Photograph the bag, the label, and the location it came from.

A damage scene degrades by the hour. Salvage crews, well-meaning owners and the next tide will all destroy evidence. Your photos are the record.

Cause-of-loss reasoning

The hardest part of a damage report is the cause-of-loss section. Three principles:

  • State what's consistent with the evidence, not what you believe happened. "The damage

pattern is consistent with impact from a floating object travelling at low speed" is defensible. "The vessel struck a log" is not, unless you saw the log.

  • Rule out alternatives explicitly. "No evidence of pre-existing structural defect was

observed in the affected area. The damage is therefore not consistent with delaminated laminate failing under normal loading."

  • Hedge appropriately. "On the balance of probability" and "in the surveyor's opinion" are the

right registers for cause-of-loss conclusions.

The report structure underwriters expect

1. Instruction summary (who, when, what scope) 2. Vessel particulars 3. Site conditions on inspection (weather, tide, vessel position) 4. Damage description, area by area, with photos 5. Cause of loss analysis 6. Pre-existing condition assessment 7. Cost of repair estimate (if instructed) 8. Salvage and recovery considerations 9. Recommendations 10. Photo appendix (numbered, captioned, dated)

The cost of repair estimate should reference written quotes from named yards where possible, not a single surveyor estimate. Underwriters trust quotes more than opinions.

Pre-existing condition is half the job

The single most valuable thing you can do for an underwriter is establish whether the damage was caused by the event claimed, or by a pre-existing defect the policy doesn't cover.

Look hard for:

  • Old repairs in the affected area
  • Corrosion or rot adjacent to the damage
  • Wear patterns inconsistent with the alleged event
  • Maintenance records that suggest known prior issues

A clear pre-existing condition finding can save an underwriter hundreds of thousands of pounds and is the work that earns you panel positions.

Documentation is the deliverable

Claim surveys produce vastly more evidence than pre-purchase work — 200–600 photos is normal, plus written quotes, owner statements and site diagrams. Keeping that evidence organised and tied to specific findings is the difference between a usable report and a folder of clutter.

Modern survey software like evalo attaches photos directly to each observation during capture, so a 400-photo damage survey stays navigable. The PDF export keeps each finding bundled with its evidence, which is what an adjuster needs to make a decision.

Fees

Damage surveys are billed at a day rate or hourly, not per-foot. Typical UK figures:

  • Site attendance: £600–£900/day plus travel
  • Report writing: £80–£120/hour, typically 8–20 hours depending on complexity
  • Follow-up meetings, expert witness work: £150–£250/hour

Always quote a range with caveats, and bill in stages — preliminary, full report, follow-up — so both you and the instructing party can pause if scope changes.

Insurance for you

Make sure your professional indemnity cover explicitly includes claim and damage survey work. Some default PI policies for surveyors exclude it or require an endorsement. The premium uplift is small; the exposure without it is career-ending.
