Living on the water is a great way to spend a season. Morning light on the dock, a boat ready at the slip, and a view that never gets old are the reasons people buy waterfront in the first place. Storm season is the other side of that deal. Wind, surge, and heavy rain can damage a dock, a boat, and a house in the same night, and the best time to get ready is weeks before anyone mentions a named storm.
This guide gives lake and coastal owners a plain checklist. It starts with the plan, moves through the dock, lift, and boat, and ends with the house and the first look after the weather passes. Use it as a starting point and adjust it for your marina rules, your local conditions, and your boat’s owner’s manual.

Start With a Storm Plan Before the Season Begins
A plan makes every later decision easier. Decide now where the boat will be when a storm approaches. Some owners haul out and store the boat on land. Others leave it in a slip, on a lift, or at a marina with its own storm procedure. The right answer depends on the boat, the size of the storm, and how much notice you get, so ask your marina what it requires and when.
Then gather the paperwork. Take dated photos or video of the boat, the dock, and the house, including the engine and electronics. Keep a copy of your registration, insurance policy, and contact numbers somewhere you can reach without power. Read your policy for named storm clauses, since some have deductibles or deadlines for moving a boat.
Finally, choose a trigger. Many owners set a date, such as the start of the season, to finish prep, and a second trigger for when a storm enters the forecast cone. When the second trigger hits, you should only be finishing a list, not starting one.
Secure the Dock, Lines, and Boat Lift
Most storm damage on the water starts with something moving that should not. Lines chafe through, cleats pull out, and a boat that shifts a few feet can slam into a piling all night.
Dock Lines and Cleats
Use more lines than you would on a normal day, and use heavier ones. Run them at different angles so the boat stays centered if the wind shifts. Leave enough slack for rising water, because a boat tied tight can be pulled under or tear out hardware as the level climbs. Add chafe guards where lines pass through fairleads or over edges, and check every cleat for loose bolts or cracks.
Inspect the lines themselves. Old, stiff, or frayed rope is a poor bet in a storm, and replacing it costs far less than repairing a damaged hull.
Boat Lifts and Canopies
If your boat sits on a lift, follow the lift manufacturer’s guidance on whether to raise it or lower it for a storm, since the right setting depends on the design and the expected water level. Secure the boat to the lift with straps or lines, and remove the canopy, cover, and bimini top, which can act like a sail in strong wind.
Take everything loose off the dock and the boat. Cushions, fenders, fishing gear, and cooler lids all become projectiles, so store them indoors.
Check the Bilge Pump, Fuel, and Battery
These three systems keep a boat afloat and ready if conditions change. Before storm season, check your bilge pump, fuel system, and battery, and stock a few marine engine parts such as filters and spark plugs so you are not waiting on shipping after the weather clears.
Start with the bilge pump. Test it by lifting the float switch or using the manual switch, and make sure it moves water out through the discharge. Clear any debris from the bilge, and check the hose and connections. A pump with a weak battery behind it will not run long, so the battery matters as much as the pump.
Check the battery next. Look for corrosion on the terminals, confirm it holds a charge, and keep it topped up with a charger or maintainer if the boat will sit. Many owners also replace a battery that is several years old before storm season, because a weak one often fails when it is needed most.
For fuel, aim for clean and fresh. Old fuel can gum up a system, and ethanol blends can absorb moisture over time. Many manufacturers recommend a fuel stabilizer for boats that sit, so check your engine’s guidance. Inspect fuel lines, the primer bulb, and the water-separating filter for cracks, leaks, or water in the bowl.
- Test the bilge pump and float switch, and clear the bilge
- Charge the battery and clean the terminals
- Check fuel quality, stabilizer, lines, and filters
- Confirm the boat’s drain plugs and through-hull fittings are secure
Prepare the Engine Before the Weather Turns
An engine in good shape is easier to protect and easier to restart after the storm. Check the oil level and condition, and replace the oil and filter if you are close to the service interval in the owner’s manual. Look at hoses and clamps for cracks or loose fittings, and check the belts for wear.
If you run in salt or brackish water, flush the cooling system after your last outing and rinse off salt from the powerhead. Inspect the water pump impeller if it is due, since a worn one is a common cause of overheating and is cheap to replace compared with an engine repair.
A small spares kit is worth building now. Keep it in a dry, labeled container so you can find it fast.
- Spare fuel filters and a water-separating filter element
- Spark plugs, if your engine uses them
- Impeller kit, drive belts, and a few hose clamps
- Fuses, bulbs, a basic tool set, and a flashlight
Spares matter because storms often strain delivery routes. A part that ships in two days in July can take much longer when roads close and shops fill up.
Protect the Waterfront Home
The house deserves as much attention as the boat. Clear gutters and downspouts so heavy rain drains away from the foundation. Trim dead branches, secure or store patio furniture, grills, and planters, and bring in anything light enough to blow around. If you have shutters or storm panels, test them before you need them.
Check the sump pump if you have one, and confirm that it works and that the discharge line is clear. Consider a battery backup for it. If you plan to use a portable generator or power station for essentials, keep it outside and well away from windows and doors. Never run a generator indoors or in a garage, because carbon monoxide builds up quickly. Store extra fuel safely and follow local guidance.
Keep a go bag ready with medications, documents, chargers, water, and cash. If officials order an evacuation, leave. A boat and a dock can be replaced, and you cannot.
A Simple Timeline for Storm Prep
Breaking the work into stages keeps it manageable.
- Before the season: service the engine, test the pump and battery, replace worn lines, and build the spares kit
- When a storm is in the forecast: confirm the marina plan, fuel up as advised, remove canvas and loose gear, and double up lines
- In the last day or two: finish securing the boat, photograph everything, turn off nonessential systems as your manual advises, and leave the area if told to
Do not stay aboard to ride out a storm. Once conditions turn, a boat in a slip is no place for a person.
After the Storm: Inspect Before You Start Up
Return only when local officials say it is safe. Look at the dock, pilings, and lines first for damage and sharp edges. Check the boat for water in the bilge, shifted straps, cracked fittings, or a hull that rubbed against a piling.
Do not start an engine that has been submerged or has taken on water. Water in cylinders or the fuel system can cause serious damage when the engine turns over. Take photos for your insurer, then call a marine mechanic before attempting anything. If the boat sat dry and secure, check the oil for a milky look, drain the water-separating filter, and confirm the battery is healthy before the first start.
Final Thought
Storm prep is easier when it is routine. A few hours on the dock, the bilge, and the engine each season can save a boat, protect a house, and keep a bad week from becoming a bad year. Finish the plan before the first forecast, keep your spares close, and let the weather pass knowing the work is done.
FAQs
When should I start preparing a boat for storm season?
Start before the season begins. Service the engine, test the bilge pump and battery, and replace worn lines in advance, then use the forecast only to trigger the last steps.
Is it better to haul a boat out or leave it in the slip?
It depends on the boat, the marina, and the storm. Ask your marina about its storm procedure, and check whether your insurance policy sets any requirements.
What should I keep in a storm spares kit?
Fuel filters, spark plugs if your engine uses them, an impeller kit, belts, hose clamps, fuses, and basic tools. Check your owner’s manual for the right parts.
Can I run a generator for my waterfront home during a storm?
Many owners do, but only outdoors and well away from windows and doors, because of carbon monoxide risk. Follow the generator manufacturer’s instructions and local guidance.
