Hurricane Prep: Securing Your Boat

Hurricanes are “storms that can bring intense winds, heavy rain, floods, a storm surge, landslides, tornadoes, and coastal erosion” ( These storms are capable of causing incredible damage, and the key to protecting your boat is planning and preparation.

If a boat causes damage during a natural disaster, the owner/operator could be held responsible. Securing your boat for strong winds and storm conditions is possible, with the following recommendations from Florida Sea Grant, and the National Oceanic and Atmospheric Administration (NOAA).

Preparing Your Boat for an Incoming Hurricane

Every boat owner needs to have a plan that is designed to fit their boat type, the local boating environment, the severe weather conditions, and the characteristics of safe havens and/or plans for protection. After you have made anchoring or marooning preparations, it is important to remove all of the valuable equipment from your boat. You should also remove all movable equipment, such as:

  • Canvas
  • Sails
  • Dinghies
  • Radios
  • Cushions
  • Bimini tops
  • Roller furling sails

Secure anything that cannot be removed such as tillers, wheels, or booms. Make a list to keep track of the items that you have removed from the boat and those that you have left.  Ensure that you have sealed all openings (using duct tape) to make your boat as watertight as possible. The electrical system should be off unless you plan to leave the boat in the water.  

Consolidate all documents including:

  • insurance policies
  • a recent photograph or videotape of your vessel (and a photo which includes the hull number)
  • boat registration
  • equipment inventory
  • lease agreement with the marina or storage area
  • telephone numbers of appropriate authorities, such as
    • Marina, Harbor Master, or similar entity
    • Coast Guard or local law enforcement
    • insurance agent
    • local emergency management or emergency services

You should keep these documents in your possession, inside of a locked water-proof box. This ensures the documents are accessible as you assess your boat after the hurricane.

Securing Your Boat on a Trailer

According to the National Oceanic and Atmospheric Administration (NOAA), the most effective way to secure your boat is by trailering it and pulling it to high, dry land.

Before moving your boat, you should be sure that your vehicle is capable of properly moving the boat. Check the condition of your trailer’s tires, bearings, and axle.

Once you have placed your boat in a safe location, lash your boat to the trailer and place blocks between the frame members and the axle inside each wheel.

If you own a lightweight boat, consider letting out approximately half of the air in the tires, then filling the boat one-third full of water to help hold it down. Be sure to consult your boat’s manufacturer for the best procedure to do this.

Secure your boat in place by tying it down with heavy lines to fixed objects. Your boat can be tied down to screw anchors secured in the ground.

If possible, try to pick a location that allows you to secure your boat from four directions. This is because hurricane winds rotate and change directions.

Securing Your Boat on a Lift

According to BoatUS Marine Insurance, boats on lifts or davits should be stored ashore or moved to a safer location in the water whenever possible.

However, if your boat must remain on its lift, remove the drain plug so that the accumulated water will drain and prevent the lift from collapsing. Tie the boat to its lifting machinery to prevent it from swinging or drifting away.

You should also plug in the engine’s exhaust outlet and strip the boat. The cockpit drains should also be free of debris.  

Securing Your Boat in the Water

If you choose to leave your boat docked, consider the dock lines that you use to secure it.

Approximately 50% of boats that have been damaged at fixed docks, during hurricanes, could have been saved by using better dock lines. Use dock lines that are long, large, arranged well, and protect against chafing. For most boats, you should use:

  • ½” line for boats up to 25 feet in length
  • 5/8” line for boats 25 feet to 34 feet
  • ¾” to 1” lines for larger boats

You should have chafe protectors on any portion of the line that could be chafed by chocks, pulpits, pilings, etc.

“If you need chafe protection quickly, use duct tape (a lot) to secure several layers of heavy canvas to the lines. It isn’t pretty, but works surprisingly well.”     – BoatUS Marine Insurance

Secure your lines to strong, wooden pilings. These pilings can stand up to lateral stress and twisting, as opposed to concrete pilings that cannot.

In order to reduce windage, the bow of most boats should face the least protected direction. However, if your boat has swim platforms, especially those integral to the hull, this is not the case. If the swim platform cannot be kept safely away from the bulkhead, secure the boat with its stern towards the water. This helps prevents the boat from sinking due to the platforms being bashed against the bulkhead.

  2. A boat from a marina across my private dock tied a 60′ boat to my dock with out my permission in preparation for Irma. What are the liabilities involved in untying the boat from my dock? I am furious with what they did. I think it’s trespassing and that the marina should take care of their renters.

    • Good morning, Jean,
      I’m so sorry to hear about the issue you had with the neighboring marina. If your dock sustained any damage as a result of this action, I would encourage you to seek professional legal advice. The information we are sharing here for boat owners isn’t meant to be used in legal situations but instead, to help our fellow Floridians prepare as best as possible for an incoming storm event. Again, I’m sorry to hear about the situation you described with the neighboring marina and hope your dock and the boats involved fared well in the storm. If there are any questions you might have regarding storm recovery, I encourage you to check out this list of resources from UF/IFAS Extension:
