Hurricane Prep Yacht Checklist: Owners and Charter Fleets

Every year around the first week of September I end up with the same tab open on my phone, standing on a finger pier with coffee going cold, refreshing the National Hurricane Center's five-day outlook far more often than it actually updates. Two seasons ago it was a yellow blob off Africa with a 40% development chance. I did the arithmetic on how long it would take to get my boat out of the water if that blob became something, and then I called the yard.

They were full. Not for that storm — for the season. They had sold their hurricane spaces in April to owners who signed contracts.

That is the part I wish someone had told me earlier. By the time a storm has a name, most of your options were already settled by things you did or failed to do in the spring. And the document that determines which options you were supposed to arrange is not the forecast. It is your own insurance policy, in a clause most owners have never read.

A friend of mine runs six catamarans out of Tortola on a mix of bareboat and crewed bookings. When a system enters the basin, he is not thinking about dock lines at all. He is thinking about which of six hulls gets the one remaining lift slot, what he owes four sets of guests who are already booked, where his crew sleep if the base closes, and whether the APA he collected last week is already spent on provisions nobody is going to eat.

Those are two genuinely different problems. This covers both. If you want the granular hour-by-hour version for a single boat in Florida, the Florida owner's deep-dive guide already walks through the 30-day, 7-day, and 24-hour countdowns in detail — I am not going to re-derive it here.

Your policy decides more than the forecast does

Pull up your policy schedule before you read another storm model. Three lines on it govern everything else.

The named-windstorm deductible. Most policies written in hurricane-exposed regions carry two deductibles: a small fixed one for ordinary claims, and a separate percentage-of-agreed-value deductible that applies only when a named storm caused the damage. That percentage commonly runs 2%, 5%, or in some markets 10%. Take a hypothetical yacht insured at $400,000 with a 5% named-windstorm deductible — that is $20,000 out of pocket before the policy contributes a dollar. Illustrative numbers, but the shape is real, and it reframes what "insured" means in September.

The haul-out warranty. Most Caribbean and US hurricane-zone policies carry a named-storm warranty requiring the vessel to be moved to a nominated location, often out of the water, within a set window once a storm is named for the area. Forty-eight to seventy-two hours is typical. Some insurers also require a written hurricane plan on file, or a copy of the marina's own windstorm procedures, or a signed haul-out contract produced in advance rather than arranged in the moment. Miss the window and storm cover for that event can be voided outright.

The geographic limits. In the Caribbean this shows up as a hurricane box, and there is no industry standard for where its southern edge sits. A frequently cited line is 12°40'N, which keeps most of Grenada inside. Some insurers use 12°30'N. Markel American's Jackline policy moved its boundary down to 10°50'N, which changed the answer for boats wintering in Grenada, Isla Margarita, the ABC islands, and Tobago. Others run to 9°N and take in Trinidad. Your schedule is the only authority here.

If you read nothing else this season, read those three lines. They convert a vague sense of "I should probably do something" into a specific list of obligations with deadlines attached — which is what the underwriter is going to hold you to.

The short list, for one boat

The pre-season work is unglamorous and almost entirely about being early.

• Get a haul-out or storage contract in writing before June. A phone inquiry is not a reservation and a reservation is not a contract. Ask about lift capacity, beam and draft limits, and the yard's own cutoff for accepting vessels. Line up a second yard, ideally inland or in a different county.
• Photograph everything and put the documents somewhere you can reach from a car. Hull, deck, cockpit, interior, electronics with serial numbers visible. Store them with the policy schedule, registration, haul-out contract, and the marina's written storm procedures.
• Test the systems that only matter during a storm. Every bilge pump, every float switch cycled by hand, the high-water alarm, the batteries at full charge, the emergency pump on independent power. Seacocks that move.
• Buy the consumables in May. Extra lines sized for the boat, chafe gear, fenders. Chafe is what actually parts dock lines — constant sawing at chocks and pilings — and the sections of fire hose everyone swears by are gone from the chandlery the week a storm is named.
• Write down who decides, and who acts. If you are 800 miles away, someone else is moving your boat. Name them now, tell the marina who they are, and put it in the same folder as the policy.

Dock, haul, or relocate

This is the decision people agonize over, and it resolves faster than expected once you sort by vessel type.

Trailerable, roughly under 28 feet. Trailer it inland and stop thinking about it. This is the cheapest and most reliable answer available to any owner, and it is the reason smaller boats survive storms that destroy larger ones.

Thirty to fifty feet in a marina. The question is what kind of marina. Floating docks on pilings tall enough to handle the surge are a materially different proposition from fixed docks, where rising water simply lifts the boat over the pier and drops it back down on top of it. Storm surge of eight to fifteen feet above normal high tide is not exotic in a major hurricane. If you are staying, lines need to be long enough that surge does not snap them, run at wide angles, tied high on the pilings, with chafe protection at every contact point.

Above fifty feet, or deep draft. Hauling gets expensive and the yard's capacity becomes the constraint rather than your willingness to pay. Jackstands need chains and plywood pads; a yard that stores boats close-packed on stands in a hurricane zone should be able to explain its tie-down scheme without hesitating.

Sailing vessels with crew and time. Relocating south of the box is a real option and it is also a multi-day passage, not a 48-hour decision. It has to be committed to while the storm is still a tropical wave. And it is worth staying honest about what "safe haven" means: Grenada has been hit four times in a hundred years, and Ivan destroyed hundreds of yachts there in 2004. Lower probability is not immunity.

The 2026 season, for what it is worth, has run below normal — NOAA's August update held at 7 to 13 named storms with 2 to 6 hurricanes, and gave a 75% chance of below-normal activity. That is useful for planning and useless for any individual boat. A below-normal season that produces one landfall over your slip is, from where you are standing, a bad season.

For charter operators: the part nobody writes a checklist for

Everything above applies to your hulls too. It is also the easy half of your problem. What follows addresses you directly.

Your storm clause is part of the product

Many Caribbean operators attach a named-storm addendum to bookings between June and November: if a named system affects the charter dates or the cruising area, the guest reschedules or takes a credit. That is a reasonable structure, and the operators who get burned are not the ones with a stingy policy — they are the ones whose policy was ambiguous, or was explained for the first time while a guest was watching the same NHC cone you were.

Settle three questions before the season opens and publish the answers at the point of booking:

1. What triggers it. Usually a named tropical system whose warning area or forecast track covers the cruising ground or the base during the charter window. Say so in those terms.
2. What the guest gets. Reschedule, credit, or refund — and the timeline. Credits protect your cash position; refunds protect your reviews. Pick deliberately, price it in, and do not improvise it per guest in the middle of a threat, because guests compare notes.
3. Who decides. The captain or base manager makes the operational call and the guest does not get a vote. Writing that into the agreement is what stops a paying customer from negotiating with a captain about whether to run to a mooring field.

Tell guests to buy travel insurance at booking, and tell them why the timing matters: once a storm is named and on the tracker, insurers stop selling cover for trips it might affect. It cannot be bought retroactively. Cancel-for-any-reason riders typically add 40–60% to the base premium and reimburse up to around 75% of non-refundable costs — roughly $700 to $1,200 on a $30,000 charter, as an illustrative range. A guest who hears that in April can act on it. A guest who hears it in September cannot.

Guest communication runs on a clock

Three touches, and the timing matters more than the wording.

At booking, the policy is stated in writing and the insurance recommendation goes with it. At roughly seven days out, when a system is in the basin and the cone is wide, you send a short note that does two things: acknowledges the system exists, and names the date and time you will make a decision. At 72 hours, you make that decision and communicate it, whichever way it goes.

The failure mode is silence. Guests who have not heard from you are not waiting patiently — they are reading forecast discussions they cannot interpret, calling the airline, and filling the vacuum with worst cases. A decision deadline you name in advance and then actually hold is worth more to them than a favorable answer delivered late.

APA, and money already in motion

The awkward part of a storm cancellation is that the money has usually moved. Provisioning is bought. Dockage is prepaid. The crew has been rostered. If you reconcile APA at the end of the season rather than per booking, a storm week turns into an argument you cannot document.

Reconcile per charter, keep receipts against the specific booking, and be able to show a guest exactly what their advance was spent on before you discuss what comes back. The same per-charter discipline that makes storm refunds defensible is what makes the rest of the year legible — the mechanics are in tracking profitability per charter.

Sequencing a fleet is not securing a boat

One owner makes one decision. You make six, and they compete with each other.

Travel-lift slots are finite, tide windows are finite, and the yard crew goes home at some point. The sixth boat in your queue may simply not get hauled. That outcome is decided months earlier, by whether you pre-assigned each hull a destination and a queue position, or whether you planned to sort it out when the time came.

Rank each vessel on three things: insured value, how exposed its current berth actually is, and how feasible it is to move. Then give every hull a named destination — this yard, that hurricane hole, that mooring — and a position in the order. Vessels that cannot be hauled need their in-water plan written now, not discovered on the day. Across two bases, the question is also which base releases capacity to the other and who has authority to make that call at 2am. For operators working the BVI specifically, the regulatory and operational context for 2026 is worth a look alongside this.

Crew have their own storm

Crew are the piece that gets planned last and matters most. They have homes, families, and in many bases they are not local, which means when the base closes they have nowhere obvious to go.

Decide in advance who stays to work vessels, who is released, and who gets housed and where. If hulls relocate to another base, work out whether crew travel with them, how they get back, and who pays for the flights and accommodation — before the flights are full and the answer becomes whatever you can find. Contracted crew need their storm obligations spelled out in the contract rather than assumed. The staffing and rostering side of this is covered in more depth in crew management for charter fleet operations.

Guests aboard when a storm is named

For bareboats, the recall procedure needs to exist in writing and be handed to guests at the chart briefing, not emailed mid-charter: where they go, by when, who authorizes it, what the radio and phone protocol is, and what happens if they are three islands downwind. For crewed charters, the captain's authority is absolute and the contract should say so plainly, so nobody is litigating the chain of command with a squall line on the radar.

And once a recall is issued, the vessel is a fleet asset again, not a charter. It goes into the sequence with the rest.

After it passes

Document before you touch anything. Shoot the same angles as your pre-season set, interior included, bilge included, waterline and debris marks included, timestamps intact. The before set is what gives the after set its value.

Do not start the engine and do not energize systems until the boat has been checked for water ingress. A partially submerged engine that gets cranked stops being a repairable claim and becomes a replacement. Notify the insurer early, and keep receipts for emergency pumping, towing, or hauling — most policies cover reasonable costs to prevent further damage, but only if you can show what you spent.

Then log the whole event: what was done, when, what it cost, what failed. Storm history that lives in a text thread evaporates. Storm history that lives in the vessel's record is what a surveyor, an underwriter, or eventually a buyer will want to see, and it is part of what maintenance documentation does to resale value.

Where OwlMar fits

The two failures that keep repeating are timing and retrieval. The spring tasks slip because nothing prompts them, and the documents you need at 5am in a car heading inland are in a filing cabinet on the boat.

OwlMar's automated seasonal reminders handle the first — haul-out contract, pump test, line inventory, policy review — as scheduled items rather than things you remember in August. The Digital Ship's Vault handles the second: policy schedule, haul-out contract, marina storm procedures, registration, and pre-season photographs, searchable from a phone. For multi-vessel operators, the fleet-wide dashboard puts every hull's status, location, and open work in one view, which is the view you want when you are sequencing six boats and one lift. If you want to ask something specific before signing up for anything, the Help Co-Pilot on the site will answer it.

Single-boat owners can start at owner-operators. Charter operators running multiple hulls should start at charter.

Either way, the hour of the season that pays for itself is the one you spend reading your own policy schedule. Everything else on this list is downstream of what you find there.
