Sea Trial Liability: Protecting Your Shop During Test Runs

After completing engine work, drive repairs, or other critical systems, a sea trial is often the only way to verify the repair was successful. But the moment that customer's boat hits the water with your employee at the helm, you've taken on significant liability. Here's what you need to know about protecting your business during sea trials.

Why Sea Trials Create Unique Risk

When you take a customer's boat out for testing, several things change:

1. You're operating the vessel: Any damage that occurs is clearly your responsibility 2. You're on the water: Risks multiply — collision, grounding, sinking 3. The boat may have unknown issues: You're testing it precisely because something might be wrong 4. Other boaters are involved: Potential third-party liability 5. Environmental factors: Weather, water conditions, obstacles

A routine sea trial can quickly turn into a major claim if something goes wrong.

Coverage Considerations for Sea Trials

Garage Keepers Liability

Your garage keepers policy is your primary protection for damage to the customer's boat. However, not all policies cover in-water operations. You need to verify:

- Does your policy cover boats while waterborne?

  • Are there exclusions for operation vs. storage?
  • What are the limits for in-water damage?

    Some policies only cover boats while at your premises or in storage. If your policy has this limitation, you need an endorsement or separate coverage for sea trials.

    General Liability

    Your GL policy covers third-party injuries and damage. During a sea trial, this might include:

    - Collision with another vessel

  • Wake damage to docks or other boats
  • Injury to passengers (if you allow them during tests)
  • Property damage at marinas or launch ramps

    Again, verify your policy doesn't exclude waterborne operations.

    Marine General Liability

    For businesses that regularly conduct sea trials, a marine general liability policy may be more appropriate than standard GL. Marine GL is designed for over-water operations and typically provides broader coverage for maritime risks.

    Protection & Indemnity (P&I)

    If you operate your own vessels (not customer boats) for any purpose, you may need P&I coverage. This is the maritime equivalent of auto liability and covers:

    - Crew injuries

  • Collision liability
  • Wreck removal
  • Pollution

    Best Practices for Sea Trial Risk Management

    Before the Sea Trial

    1. Document the boat's condition: Photos and written notes before departure

2. Review customer's insurance: Know if they have hull coverage 3. Check weather conditions: Postpone if conditions are marginal 4. Verify the work completed: Double-check critical systems before launch 5. File a float plan: Let someone know where you're going and when you'll return

During the Sea Trial

1. Use qualified operators: Only experienced employees should conduct trials 2. No passengers: Limit who's on board to essential personnel 3. Stay in familiar waters: Know the area — hazards, depths, traffic 4. Progressive testing: Start slow, build up to full operation 5. Monitor systems continuously: Watch gauges, listen for problems

After the Sea Trial

1. Document results: Note all observations about boat performance 2. Report any incidents immediately: Even minor ones 3. Photograph the boat's condition: Upon return to your facility 4. Complete service records: Full documentation of the trial

Common Sea Trial Claims

Understanding what goes wrong helps prevent future incidents:

Grounding

Running aground is one of the most common sea trial accidents. Causes include:

- Unfamiliar waters

  • Incorrect charts or GPS
  • Distraction during testing
  • Shallow water at low tide

    Prevention: Know your testing waters, always check tide charts, use depth finders.

    Mechanical Failure

    Sometimes the repair wasn't successful, or another system fails during testing:

    - Engine overheating

  • Steering failure
  • Drive problems
  • Fuel system issues

    Prevention: Progressive testing, continuous monitoring, not pushing systems too hard initially.

    Collision

    Contact with other vessels, docks, or fixed objects:

    - Backing into the dock

  • Striking a moored boat
  • Collision with another moving vessel
  • Contact with pilings or seawalls

    Prevention: Slow speeds near obstacles, proper lookouts, experienced operators.

    Weather

    Getting caught in unexpected weather:

    - Sudden storms

  • High winds
  • Reduced visibility
  • Rough seas

    Prevention: Check forecasts, stay close to shore, cut trials short if conditions deteriorate.

    Should You Allow Customer Observation?

    Some customers want to be present during sea trials. Consider:

    Pros:

  • Customer sees the repair work performed properly
  • They can describe symptoms while underway
  • Builds trust and satisfaction

    Cons:

  • Additional liability for passenger injury
  • Customer may interfere with testing
  • Distraction for your operator
  • Potential witnesses to any problems

    If you allow customers on sea trials, get a signed waiver acknowledging the inherent risks. Also verify your liability coverage includes passengers.

    Alternatives to Sea Trials

    When possible, consider alternatives that reduce risk:

    1. Static testing: Run engines at the dock with load simulators

2. Portable diagnostics: Use computer diagnostics to verify systems 3. Customer test drive: Let the customer operate with your tech aboard 4. Limited trials: Shorter durations, closer to shore 5. Professional captains: Hire licensed operators for high-value vessels

Getting Proper Coverage

Sea trial liability is too important to guess at. We recommend:

1. Review your current policies: Confirm in-water coverage exists 2. Discuss operations with your agent: Be specific about your sea trial practices 3. Consider marine-specific coverage: If standard policies have gaps 4. Document everything: Good records protect you in claims

Protect Your Business on the Water

Sea trials are a necessary part of quality marine repair. Make sure you're properly protected before that customer's boat leaves the dock.
