Important evidence may change once the vessel is:

  • Moved

  • Hauled

  • Cleaned

  • Dried

  • Dismantled

  • Repaired

  • Salvaged

  • Modified

Damaged components may also be discarded during repair.

Prompt inspection can help create an independent record before those conditions change.

Photographic Marine Documentation

Photographs are an important part of damage-survey reporting.

Depending upon the casualty, documentation may include:

  • Overall vessel views

  • Damaged areas

  • Close-up photographs

  • Context photographs

  • Machinery

  • Electrical equipment

  • Structural components

  • Running gear

  • Identification numbers

  • Other relevant evidence

Photographs help provide insurers, vessel owners, attorneys and repair facilities with a visual record of conditions observed during the survey.

Out-of-Water Damage Inspections

Certain casualties require access to underwater components.

Haul-out should be considered following suspected:

  • Grounding damage

  • Propeller strikes

  • Shaft damage

  • Rudder damage

  • Hull-bottom impact

  • Sterndrive damage

  • Keel damage

  • Underwater collision

The boatyard or marina normally performs the physical haul-out while the marine surveyor conducts the inspection.
