A tug or towboat crash is devastating in many ways. When vessels collide or equipment fails, how do you even save evidence on the water? In Memphis, Tennessee, preserving evidence is a crucial part of filing a claim. Unfortunately, many victims do not know where to begin and miss evidence that could prove what happened and help them pursue fair compensation.
What types of evidence matter most?
Preserving evidence after a tug or towboat crash is a race against time, the current and company interests. Federal maritime rules, including the Jones Act, demand more technical documentation than a typical auto accident. Currently, these are the most common forms of evidence you can use to file a claim:
- Voyage Data Recorder (VDR / S‑VDR): The vessel black box records bridge audio, radar, GPS and engine data and often shows what really happened. These units only hold 12 to 48 hours of data so early preservation is important.
- Automatic Identification System (AIS): AIS provides a GPS replay of a vessel’s course, speed and heading to rebuild the timeline and show who did what. Port authorities, vessel owners or third-party services often hold the logs for these.
- Deck and engine room logs (vessel logs): Crew write these logs to record shifts, weather, cargo moves and equipment problems. Courts and investigators treat these entries as key proof for injury claims.
- Maintenance and inspection records: Repair orders, inspection reports and maintenance logs show proof of seaworthiness. Keep originals or certified copies and note who created each record so you can prove skipped repairs or broken procedures.
Once this information disappears, recreating events relies on memory alone, which can weaken a claim. In many cases, a lawyer will have to send written requests to preserve or freeze evidence. Note that Tennessee’s timeline on boat accident claims allows only 1 year from the date of the accident, so consider early legal guidance.
Do not let your claim sink with fading evidence
Evidence vanishes fast on the water and technical data can be overwritten in days, so you must act fast to collect them. The sooner you preserve your proof, the higher the chance you can support your claim with sufficient information.
