If you own a boat in a hurricane-prone area, storm preparation isn’t optional—it’s the difference between a close call and a total loss. Whether your boat lives in a slip, mooring, trailer, or dry storage, the same fundamental goals apply: reducing windage, controlling water intrusion, securing against surge, and removing anything that can become a projectile.
However, with this year’s El Niño pattern already among the strongest on record—and still strengthening—your standard checklist may need revisiting.
This guide covers what you need to know about this year’s storm pattern and what to do about it before the season ends on November 30.
What El Niño Means for Hurricane Season
In a typical El Niño pattern, warmer ocean temperatures shift storm behavior, suppressing hurricane activity in the Atlantic while ramping it up in the Pacific. This change also flips the script on expected fall and winter weather across the country, causing some areas known for their dry, mild environments to see wetter, stormier conditions and vice versa.
So far, for 2026, this is exactly what we’ve seen—just supercharged.
On the Atlantic side, things have been historically quiet, with the first hurricane arriving unusually late on October 9, while the Pacific has logged 20 named storms and nine hurricanes. NOAA’s October advisory put sea surface temperature anomalies at more than 4°C above normal in the eastern equatorial Pacific, with greater than 83% odds of a “strong-to-very strong” event through January-March 2027.
Suffice it to say, Pacific Coast boat owners face a rough season, making thoughtful preparation more important than ever. But Atlantic-based owners shouldn’t think they’re off the hook.
Fewer storms doesn’t mean safer. This month’s Hurricane Isaias landed as a Category 2, killing four people and knocking out power for nearly 670,000 homes—and back in 1992, during another strong El Niño year, Hurricane Andrew slammed into Florida as a Category 5 and became one of the most destructive hurricanes in U.S. history.
Basically, one storm is all it takes, and the best time to prepare is before it has a name. The checklist below covers what to do.
Hurricane Boat Prep Checklist
The steps below apply whether your boat lives in the water, on a trailer, or anywhere in between.
Decide where the boat will ride it out, and act early.
The single biggest decision when prepping for storm season is boat location—and the earlier you make it, the better.
If your boat is trailerable, the safest option is almost always to haul it and move it inland, away from tidal influence and falling trees. A garage or solid structure is ideal, just remember that storm surge can travel farther inland than most people expect. Before the season gets any later, give your trailer a once-over, evaluating tire pressure and condition, wheel bearings, light functionality, and brakes. You don’t want to discover problems when every boat ramp is crowded and all the shops are booked solid.
If you’re storing the trailered boat outside rather than under cover, let a little air out of the tires, block the wheels, and strap the boat down to any solid anchor points you can find. Stay clear of trees.
For boats that stay in the water, think about a more protected slip or a true hurricane hole if one is available. Talk to your marina now about their policies and any haul-out windows. Fixed docks need extra attention because surge can lift the boat higher than the cleats or lines were designed for. Floating docks are often better in surge, provided the pilings are tall enough.
If the boat is already on the hard, make sure it’s elevated well above any realistic surge height. Extra jack stands, chained together and sitting on plywood pads, help keep everything stable if the ground softens. Some owners add straps or ground anchors tied to concrete eyes for additional security. It’s not glamorous work, but it’s the kind of preparation that pays off if the water rises farther than expected.
Strip the windage.
Once location is settled, the next job is reducing windage. Anything that sticks up or can fill with air becomes a liability in high winds. Take off bimini tops, canvas enclosures, sails, outriggers, antennas, and dinghies if you can. Cushions, life rings, and loose gear should come home with you. If something has to stay, lash it securely so it can’t become a projectile or a sail.
Sailboat owners often find that unstepping the mast, when realistic, removes a huge amount of stress on the boat and the docking system. Even if you leave the mast up, getting the sails off and the halyards secured still makes a noticeable difference.
Shore up your lines, fenders, and chafe protection.
For boats remaining in the water, this is where many owners make the biggest improvement. Double or even triple your dock lines and arrange them so the boat can rise with the surge without swinging into pilings or the boat next door. Think of a spider web more than a tight set of short lines. Longer lines are generally better because they allow vertical movement. Upsizing the diameter a bit if your current lines are on the light side is also smart.
Chafe protection at every point where a line touches a chock, piling, or rail is non-negotiable. Nylon stretches under load, which is good for absorbing shock, but that same stretching will saw through the line against a sharp edge. Simple lengths of hose that are cut to fit or purpose-made chafe gear work well.
Oversized fenders and a fender board help keep the hull off the dock when the water gets lively. While you’re at it, check that your cleats are through-bolted with solid backing plates and that you’re not hanging more than a couple of lines on any single cleat.
You’ll find solid dock lines, fenders, and related hardware in our Anchor & Docking collection.
Get ahead of water intrusion.
Wind gets a lot of attention but for boats, it's storm surge and flooding that do most of the lasting damage. A boat that fills and sinks, or one that is lifted and dropped onto a dock or another vessel, is far harder to recover from than one that simply loses a canvas top.
Make sure your bilge pumps are working and that the float switches move freely. Charge the batteries so the pumps can keep running if shore power goes out. A small portable backup pump is inexpensive peace of mind. Clear every scupper and cockpit drain so rain and spray have somewhere to go. Seal hatches and ports as best you can.
If the boat is on the hard, pull the drain plug so rainwater can escape. If it’s in the water, confirm the plug is secure. These are small steps that directly address the most common source of serious boat damage in a hurricane.
Check your moorings and anchoring setup.
If your plan involves a mooring, verify that it’s rated for the load your boat will put on it in extreme conditions. Inspect the chain and swivels, and double the pendant with good chafe gear. Anchoring out requires generous scope, ideally closer to 10:1 when you can manage it, plus tandem anchors set in a V formation so the boat can handle shifts in wind direction. Make sure there’s enough chain in the rode to keep the pull angle low.
Button up before you leave.
Charge the batteries, shut off anything non-essential, and take portable fuel and propane with you. Before you walk away, photograph the boat thoroughly—hull, deck, equipment, and serial numbers. Timestamped photos documenting the boat’s condition before the storm can make a meaningful difference when it comes time to file an insurance claim. Keep registration, insurance papers, and the title in a waterproof bag stored on land, not aboard.
And then leave. Never stay aboard once conditions start to deteriorate. No boat is worth it.
