Hurricane Prep for Boat Owners: A Pre-Storm Checklist That Actually Works

A named tropical storm enters the cone of uncertainty. You have somewhere between 48 and 96 hours to make decisions that determine whether your boat survives. Insurance companies will tell you that boats lost in hurricanes almost always show signs of inadequate prep — and that prep done wrong is sometimes worse than no prep at all.

This is the framework most experienced boat owners along the Gulf and Southeast use. Adapt to your boat, your slip, and your risk tolerance.

Phase 1: Days 5-3 — read the forecast carefully

Long-range hurricane tracks shift constantly. Don't act on a 5-day cone — but do start watching closely. Specifically:

• Check the National Hurricane Center at least twice daily.
• Note the storm's intensity trajectory (Cat 1 to Cat 4 over 3 days is a different planning horizon than Cat 1 staying at Cat 1).
• Read the discussion text, not just the cone graphic. Forecasters explain their confidence and the model spread.
• Identify your "go / no-go" decision point — typically when the storm is about 72 hours out and the cone shows your area in the forecast band.

This phase is for paying attention, not acting. Calling your hurricane plan now wastes effort if the storm shifts.

Phase 2: Days 3-2 — make the decision

By 72 hours out, commit to one of these strategies. They aren't equally good for every boat — pick the one that fits your situation:

Option A: Haul out (best protection, requires lead time)

• Reserve haulout the moment the cone touches your area. Yards fill up fast.
• Move to a yard inland and ABOVE the projected storm-surge zone.
• For boats under 30 ft, your trailer at home is often the safest option of all.

Option B: Storm mooring (excellent if available)

• Some marinas designate "hurricane moorings" — heavy permanent ground tackle in protected coves. If you have access, secure it now.
• These typically require pre-registration; calling 24 hours before a Cat 3 lands won't get you a slot.

Option C: Dock with extreme prep (default for many)

• Most marina contracts require you to remove the boat or upgrade your dock prep. Read your contract.
• Plan for storm surge of 4-15+ ft. If your cleats end up underwater, your dock lines are useless.

Option D: Anchor in a hurricane hole (DIY, weather-dependent)

• Specific bays designated as natural hurricane holes (mangroves, surrounded land, mud bottom). Local knowledge required.
• You're putting your boat next to other boats also at anchor. Sometimes this works. Sometimes one breaks loose and takes everyone with it.

There is no single right answer. The right answer depends on your slip's exposure, the storm's intensity, your insurance, and what's available.

Phase 3: Days 2-1 — execute prep

Now you act. Whatever option you chose, certain prep is universal:

Strip the boat:

• Remove all canvas — biminis, dodgers, sail covers, full enclosures. Anything with surface area becomes a sail in 100+ mph wind. Even folded canvas left on deck shreds.
• Remove headsails (or wrap and tape securely), boom-furl mainsails, lash booms hard amidships.
• Remove dinghies and tenders. They become projectiles.
• Strip antennas, flag staffs, removable electronics, anything else loose.
• Tape over vents and dorades that aren't already weathertight.

Plug the holes:

• Tape over cowl vents, dorade openings, anchor lockers.
• Make sure all hatches are dogged tight.
• Block scuppers temporarily if you'll be at a dock — you don't want wind-driven rain coming in.
• Check all bilge pumps and floats. Fully charge house batteries.

Document everything:

• Photo and video the boat from all angles. Date-stamped photos are critical for insurance.
• Photo the dock lines and chafe protection in place.
• Save copies in cloud storage; not just on your phone, which may be lost.

Phase 4: Day-of — dock lines and ground tackle

For boats staying at the dock, dock lines are everything. The standard suburban marina dock line setup is wholly inadequate for hurricane wind and surge.

Use real lines:

• Three-strand nylon, 5/8" for boats under 35 ft, 3/4" for larger. The stretch absorbs shock loads.
• Double or triple every line.
• Lines should be at least twice the boat's length to allow for surge — 4 ft of surge takes a 20 ft line.

Spider-web the boat:

• Run lines from every cleat to dock cleats and pilings.
• Crisscross bow and stern lines to dock points well outboard of the boat.
• Long spring lines (forward and aft) to maintain center positioning even with surge.
• Total: typically 12-16 separate lines on a hurricane-prepped boat. Yes, that many.

Chafe gear:

• Every line that crosses anything (pulpits, chocks, dock corners) needs chafe protection. Garden hose is acceptable; purpose-made chafe gear is better.
• Lines wear through in hours during a hurricane without chafe protection. The stretch + abrasion combination is brutal.

For anchor-out boats:

• Set TWO anchors — one main, one backup. 7:1 minimum scope on each. Different angles.
• All chain, no rope rode if possible. Polyester rope rode if not.
• Bridle lines off the bow with chafe protection at the chocks.

Phase 5: Day-of — your safety

Your boat is replaceable. You are not.

• Do NOT stay aboard during the storm. Boats survive sometimes; people who stay aboard often don't.
• Evacuate inland. Not to a coastal hotel — actually inland.
• Take essentials: ship's documents, registration, insurance, electronics, valuables.
• Leave a written summary of your prep with your insurance broker.
• Notify your marina office of your prep and your evacuation contact info.

Phase 6: After the storm — assess carefully

When you're allowed back to the marina:

• Don't board until safe. Downed power lines, debris, contaminated water.
• Photograph everything before touching anything. Insurance claims hinge on the documentation.
• Check for hidden damage. Hull stress, broken stringers, hidden water ingress, electronics that took saltwater.
• Engage a marine surveyor before declaring repairs done. Even apparently minor damage can hide structural problems.
• Don't run engines until you've confirmed no water in the cylinders, fuel system, or oil. Water in a diesel injector pump is an expensive lesson.

The boats that survive

Across many hurricane seasons, the boats that survive consistently share characteristics:

• Hauled out, blocked properly, on cradles strapped down (NOT just on jack stands)
• OR moored in a protected hurricane hole on commercial-grade gear
• OR docked with full strip-down + heavy redundant lines + extensive chafe protection

The boats that don't survive share characteristics too: light dock lines, canvas left up, sails left bent on, anchored on inadequate ground tackle, owners who underestimated the surge.

A hurricane is not a regular storm. Your normal seamanship instincts undersell what's coming. Treat it accordingly.
