Learn 10 essential ways to prepare your boat for a hurricane, from securing lines to documenting damage, ensuring safety and minimizing loss.
Hurricanes pose a significant threat to boat owners, particularly in coastal regions like the Gulf and Atlantic coasts, where storms can wreak havoc with high winds, storm surges, and torrential rainfall. The National Oceanic and Atmospheric Administration (NOAA) predicts increasingly active hurricane seasons due to rising global temperatures, which amplify storm intensity and rainfall. For boaters, preparation is not just a precaution—it’s a necessity to protect your vessel, minimize damage, and ensure personal safety. This comprehensive guide outlines 10 critical steps to safeguard your boat before, during, and after a hurricane, drawing on expert advice and lessons from past storms.
Why Hurricane Preparation Matters
Hurricanes bring a combination of destructive forces: winds exceeding 100 mph, storm surges that elevate water levels by 10 feet or more, waves that pound harbors, and rainfall that can exceed 12 inches in a single day. Historical storms like Hurricane Irma (2017), which recorded winds of 185 mph, and Hurricane Maria, which dumped 60 inches of rain in parts of Texas, highlight the catastrophic potential. Boats left unprepared are vulnerable to sinking, drifting, or sustaining severe structural damage. By taking proactive measures, you can significantly reduce the risk of loss and ensure your boat weathers the storm.
Below are 10 actionable steps to prepare your boat for a hurricane, complete with practical tips, specifications, and post-storm recovery strategies.
1. Relocate or Secure Your Boat
The first and most critical step is deciding where your boat will be safest during a hurricane. The best location depends on your boat’s size, type, and the storm’s projected intensity.
Options for Relocating Your Boat
- Trailerable Boats: If your boat is trailerable, haul it out of the water and move it inland, away from tidal surges and falling trees. Ensure the trailer is in good condition—check tires, wheel bearings, and brakes before hurricane season begins. Store the boat in a garage or a sheltered area, and secure it with straps or augers to the ground.
- Hurricane Holes: Move non-trailerable boats to a sheltered canal, river, or waterway (known as a hurricane hole). These areas offer protection from open water and reduce exposure to high waves. Secure the boat in the center of the waterway using multiple lines to both banks, creating a “spider web” arrangement.
- Marina Berths: If the boat must stay in a marina, double all dock lines and use cross-spring lines fore and aft. Attach lines high on pilings to accommodate tidal surges. Ensure cleats and pilings are sturdy—wooden pilings are often more reliable than older concrete ones, which can snap under lateral stress.
Specifications for Dock Lines
| Boat Length | Line Diameter | Minimum Line Length |
|---|---|---|
| Up to 25’ | 1/2” | Equal to boat length |
| 25’–34’ | 5/8” | Equal to boat length |
| Over 34’ | 3/4”–1” | Equal to boat length |
Tip: Use polyester lines for chafe resistance near chocks and nylon lines for shock absorption at pilings or moorings. Secure lines with eye splices for added strength.

2. Never Stay Aboard During a Hurricane
Staying on your boat during a hurricane is life-threatening. Winds exceeding 100 mph, combined with storm surges and potential tornadoes, create deadly conditions. Historical accounts from storms like Hurricane Hugo (1989) and Hurricane Andrew (1992) document tragic outcomes for skippers who remained aboard. For example, a skipper and his nephew narrowly escaped drowning when their trawler capsized in 15-foot seas during Hugo. Your safety is paramount—secure the boat and head inland.
Safety Tip: Develop a hurricane plan that includes evacuation routes and a designated safe location for you and your family. Share this plan with a trusted contact.
3. Remove Loose Items to Reduce Windage
Windage—the surface area exposed to wind—is a major factor in hurricane damage. High winds can quadruple in pressure when speed doubles, turning loose items into projectiles or causing structural failure.
Items to Remove
- Canvas covers, bimini tops, and dodgers
- Sails, especially roller furling headsails
- Outriggers, antennas, and life rings
- Dinghies and portable davits
- Electronics and personal belongings
Securing Remaining Items
- Lash booms, halyards, and other rigging to the deck or masthead.
- Run halyards to the masthead and secure them with a single line to reduce flogging.
- Store removed items in a secure location, such as your home or a locked storage unit.
Tip: Unstepping the mast on sailboats is ideal but time-consuming. If impractical, ensure all sails are removed and halyards are secured to prevent windage-related damage.
4. Protect Lines from Chafing
Chafing is a leading cause of boats breaking free during hurricanes. Nylon lines stretch under load, rubbing against chocks, pilings, or docks, which can cause them to fray or snap.
Chafe Protection Methods
- Neoprene Hose: Fit neoprene garden hose over lines at chafe points, securing with cord through drilled holes.
- Polyester Sleeves: Use polyester sleeves to protect nylon lines, allowing water to cool heated fibers.
- Heavy Canvas and Duct Tape: In a pinch, wrap lines with multiple layers of canvas secured with duct tape.
- Hybrid Lines: Use polyester lines from cleats through chocks for chafe resistance, then join to nylon lines for shock absorption.

5. Ensure Bilge Pumps and Batteries Are Operational
Heavy rainfall and storm surges can overwhelm a boat’s drainage system, leading to flooding or sinking. A functional bilge pump and fully charged batteries are essential.
Preparation Steps
- Test Bilge Pumps: Ensure automatic bilge pumps are working and free of debris. Consider adding a backup pump.
- Charge Batteries: Fully charge primary and backup batteries to power pumps throughout the storm.
- Shut Off Non-Essential Systems: Turn off all electrical devices except bilge pumps to conserve battery life.
Specifications for Bilge Pumps
| Boat Size | Pump Capacity (GPH) | Recommended Backup |
|---|---|---|
| Up to 25’ | 1,000–1,500 | 500–800 GPH |
| 25’–40’ | 2,000–3,000 | 1,000–1,500 GPH |
| Over 40’ | 3,500–5,000 | 2,000–3,000 GPH |
Cost Estimate: A quality bilge pump costs $50–$200, with backup batteries ranging from $100–$300.
6. Monitor Weather Forecasts
Staying informed about a hurricane’s path and intensity allows you to adjust your preparations. NOAA and local weather services provide real-time updates on storm tracks, wind speeds, and surge predictions.
Monitoring Tips
- Use apps like the BoatUS app for hurricane alerts and tracking models.
- Check NOAA’s website (BoatUS.com/hurricanes) for forecasts and preparation guides.
- Act early—hurricane warnings (sustained winds of 74 mph or higher expected within 24 hours) may leave insufficient time to relocate your boat.
Tip: Prepare your boat when a hurricane is a possibility, not when a watch or warning is issued, as bridges may close, and marinas may become overwhelmed.
7. Document and Inventory Your Boat
Documentation is critical for insurance claims and post-storm recovery. A detailed record of your boat’s condition and contents can expedite the claims process.
Documentation Steps
- Photograph and Video: Take high-resolution photos and videos of the boat’s exterior, interior, and equipment.
- Create an Inventory: List all items on board, including their location and estimated value. Include electronics, sails, and personal belongings.
- Secure Documents: Store boat registration, insurance policies, and marina agreements in a waterproof container or digitally in the cloud.
Sample Inventory Table
| Item | Location | Estimated Value |
|---|---|---|
| GPS Unit | Navigation Station | $500 |
| Main Sail | Sail Locker | $1,200 |
| Life Jackets (4) | Cabin Storage | $200 |
| Outboard Motor | Stern Davit | $1,500 |
8. Prepare a Hurricane Kit
A hurricane kit ensures you have essential supplies to manage preparations and post-storm recovery.
Kit Contents
- First-aid kit
- Flashlight with extra batteries
- Duct tape and cleaning supplies
- Waterproof bags for documents
- Gloves, boots, and bug spray
- Emergency contact list (marina, insurance agent, towing services)
Cost Estimate: A basic hurricane kit costs $50–$150, depending on the quality of items.
9. Secure Openings to Prevent Water Intrusion
Water intrusion from rain or surges can cause significant damage to a boat’s interior and systems.
Securing Methods
- Seal Hatches and Ports: Use duct tape or weatherproof seals to close hatches, portholes, and lockers.
- Plug Exhaust Ports: Insert plugs in engine exhaust ports to prevent water backflow (remove before starting the engine post-storm).
- Clear Cockpit Drains: Ensure drains are free of debris to prevent flooding.
Tip: Use low-residue duct tape to avoid sticky residue on surfaces.
10. Post-Storm Assessment and Recovery
After the hurricane passes, prompt action is essential to mitigate further damage and begin the recovery process.
Post-Storm Steps
- Assess Damage: Inspect the boat for structural damage, chafed lines, or flooding. Check electrical, plumbing, and mechanical systems.
- Contact Insurance: Report damage to your insurer immediately. For BoatUS policyholders, call the 24-hour Emergency Dispatch Center at 1-800-937-1937.
- Clean and Secure: Remove debris, dry the interior, and apply anti-corrosion spray to metal components. Secure the boat to prevent theft.
- Professional Help: Consult a marine surveyor or repair professional for extensive damage. Avoid entering the water due to potential electrical hazards or submerged debris.
Insurance Considerations
- BoatUS Coverage: Policies include Named Storm Haul-Out Coverage, reimbursing 50% of haul-out costs (up to $1,000) for NOAA-named storms.
- Salvage: Coordinate with your insurer before contracting salvors to avoid delays or additional damage.
Cost Estimate: Marine surveyor fees range from $20–$30 per foot, while salvage costs vary widely based on the boat’s condition and location.
Learning from Past Storms
BoatUS’s Hurricane Catastrophe Team (CAT) has analyzed thousands of claims, revealing what works and what doesn’t. Boats stored ashore, secured with multiple anchors, or moved to hurricane holes consistently fare better than those left at docks or on lifts. For example, during Hurricane Ivan, a sailboat in Gulf Breeze, Florida, survived unscathed by using three large anchors and 13 lines to shore. Conversely, boats on lifts during Hurricane Wilma were often destroyed due to storm surges lifting them off cradles.
Key Lessons
- Act Early: Waiting for a hurricane watch or warning is too late. Prepare when a storm is a possibility.
- Reduce Windage: Stripping loose gear significantly lowers the risk of damage.
- Use Robust Moorings: Helix moorings, with their superior holding power, outperformed mushroom and deadweight anchors in tests by BoatUS and MIT.
Marina and Boater Responsibilities
Review your marina’s hurricane plan and your dock contract to understand your responsibilities. Some marinas require boats to be removed during a storm, while others offer hauling services for a fee. Coordinate with marina staff and neighboring boat owners to ensure a cohesive plan.
Marina Best Practices
- Emergency Teams: Marinas like Martha’s Vineyard Shipyard maintain lists of emergency staff to assist with preparations.
- Pre-Season Preparations: Require boats to use extra pennants and chafe gear at the start of the season.
- Hauling Plans: Prioritize which boats to haul and secure storage areas above the predicted surge level.
Conclusion
Preparing your boat for a hurricane requires proactive planning, attention to detail, and swift action. By relocating or securing your vessel, removing loose items, protecting lines, and documenting its condition, you can significantly reduce the risk of damage. Post-storm, a thorough assessment and prompt insurance reporting are crucial for recovery. With climate experts predicting more intense hurricanes, these 10 steps are not just recommendations—they’re essential for every boater in hurricane-prone regions. Protect your investment, stay safe, and be ready for the storm.
