  • Assess the weight and balance of the boat.
  • Enlist enough helpers based on the boat’s weight and size.
  • Use lifting straps or slings designed for marine applications to distribute the load evenly.

When lifting manually, it is crucial to use proper body mechanics to prevent strain:

  • Keep the back straight and bend at the knees.
  • Lift with the legs, not the back.
  • Coordinate movements with other lifters to maintain balance.
  • Lift slowly and steadily, avoiding sudden jerks.

Safety measures to observe include wearing non-slip footwear, gloves for grip, and ensuring that all lifters are aware of the plan and signals for lifting and lowering.

Positioning and Stabilizing the Boat During Lifting

Proper positioning of the boat on the trailer prior to lifting is essential to maintain stability and control throughout the process. The boat should be centered laterally and supported at key points along the hull.

Use adjustable bunks or rollers on the trailer to align with the boat’s hull shape, minimizing pressure points. When lifting, maintain the boat’s center of gravity close to the lifting point to avoid tilting or slipping.

During the lifting operation, stabilizing the boat is critical:

  • Use guide ropes or tag lines to control swinging.
  • Employ blocks or supports to temporarily hold the boat once lifted.
  • Avoid sudden movements or shifts in weight.
Aspect Recommendation Reason
Boat Position Center the boat on the trailer and align supports Ensures balance and prevents damage to the hull
Lifting Points Use manufacturer-recommended lifting points Prevents structural damage and maintains stability
