Working From a Moving Boat

Key Hazards

• Workers falling overboard during acceleration, turning, or wake movement
• Hands, tools, or equipment contacting the water, motor, or structures
• Workers leaning beyond the boat's stable working area
• Task demands distracting the operator from navigation
• Loose lines or equipment creating entanglement and trip hazards
• Unexpected boat motion caused by wake, current, wind, or sudden maneuvering

2–3 Minute Talk Script

Some work requires observation, sampling, photography, inspection, or equipment handling while the boat is moving. These tasks should be planned so the worker's activity does not interfere with safe navigation or vessel stability.

The operator and worker should agree on the route, speed, work position, commands, and stop signal before the task begins. The operator should know when the worker is standing, leaning, handling equipment, or unable to brace for movement.

Workers should remain within a stable working position and avoid leaning beyond rails, gunwales, or the support provided by the deck. Reaching farther to save time can shift body weight and reduce the ability to recover from unexpected movement.

Whenever possible, the boat should be stopped, idled, anchored, or positioned to create a more stable platform before detailed work begins. The crew should not accept unnecessary movement simply because the task can technically be done underway.

Tools, poles, lines, hoses, and sampling equipment should be controlled so they cannot catch on submerged objects, strike another worker, enter the propeller area, or pull a worker off balance.

The operator should avoid sudden acceleration, turns, or wake crossings while work is active. When a maneuver is necessary, the worker should be warned and given time to secure equipment and return to a safe position.

The person performing the task should not block the operator's view or required navigation lights. Work should also stop when traffic, shallow water, structures, or other hazards require the operator's full attention.

If balance, communication, visibility, or boat control cannot be maintained, the task should pause. A safer position, slower speed, different vessel, additional crew member, or shore-based method may be required.

Safety Reminders

• Agree on speed, route, positions, commands, and stop signals.
• Use a stable working position and avoid overreaching.
• Stop or stabilize the boat when practical before detailed work.
• Control tools, poles, hoses, and lines at all times.
• Warn workers before turns, acceleration, or wake crossings.
• Keep the operator's view and navigation lights clear.
• Pause work when navigation or balance requires full attention.

Ask the Crew

• Can this task be performed with the boat stopped or stabilized?
• Where will the worker stand, brace, and place equipment?
• What movement or maneuver will require the task to stop?
• Could tools, lines, or poles enter the water or propeller area?
• How will the worker and operator communicate during the task?
