Hurricane Season Strategies for Boat Owners
Every boat owner in the tropics eventually faces the same June question: what is the plan when the tropics turn hostile? The Atlantic hurricane season officially runs from 1 June to 30 November, peaking around 10 September, and an average season now produces fourteen named storms, seven hurricanes and three majors. The strategies available — hauling out, running south, hiding in a hurricane hole, or leaving the region entirely — all work some of the time and none of them works every time. What separates boats that survive from boats that end up in salvage auctions is rarely luck. It is preparation done in May, not panic done eighteen hours before landfall.
Know your insurance box before you plan anything
Most yacht policies covering the Caribbean and the US East Coast define a named-storm zone and a date window — colloquially, the box. A classic clause excludes or surcharges coverage between roughly 12°40'N (southern Grenada) and 30°N during the season, which is why Grenada, Trinidad at 10°N, Bonaire, Curaçao and the Río Dulce in Guatemala fill with boats each summer. Read the actual wording, not the folklore: some insurers now accept boats further north with an approved hurricane plan, some impose a named-storm deductible of 5 to 10 percent of hull value, and many require specific preparations — extra lines, sails off, professional haul-out — for a claim to be valid. The insurance decision drives every other decision, so make it first, in writing, with your broker.
Strategy one: haul out and strap down
Statistically, a boat properly hauled, blocked and strapped ashore survives better than almost any boat in the water. The gold standard is a yard that drops boats into dug pits or ties them to ground anchors with hurricane straps, with masts ideally unstepped. Chaguaramas in Trinidad, the south-coast yards of Grenada, Jolly Harbour in Antigua, Peake and Power Boats in Trinidad, and Green Cove Springs in Florida all run hurricane-rated storage programmes. Book by March — the good yards sell out. Ashore is not invulnerable: boats on flimsy jackstands in crowded yards topple like dominoes, as Hurricane Marilyn demonstrated in St. Thomas in 1995. Insist on welded cradles or straps, ask how the yard fared in its last storm, and strip everything — biminis, dodgers, headsails, halyards led to the rail — because windage, not rain, is what kills.
Strategy two: go south of the belt
The migration strategy uses geography as armour. South of about 12 degrees north, hurricane frequency drops to a fraction of the eastern Caribbean average; Trinidad has not taken a direct hit since 1933. Grenada's south coast — Prickly Bay, Mt. Hartman Bay, Clarkes Court Bay — hosts a summer city of cruisers, with the caveat written in 2004, when Hurricane Ivan crossed the island as a Category 3 and damaged or destroyed the majority of boats afloat there. The ABC islands of Aruba, Bonaire and Curaçao sit further west and lower still, brushed only rarely. The continental escape hatches — Cartagena in Colombia and the Río Dulce in Guatemala — are effectively outside the climatology altogether. The price of the southern strategy is summer heat, and in some anchorages, crowding that itself becomes a hazard when a freak system does arrive.
Strategy three: the hurricane hole
A true hurricane hole is a landlocked bay with all-round protection, good holding, mangroves to tie into, and — critically — few other boats. The famous ones include Paraquita Bay in Tortola, Hurricane Hole in St. John, Ensenada Honda in Culebra, Simpson Bay Lagoon in St. Maarten, English Harbour in Antigua and Luperón in the Dominican Republic. Mangroves are superb: their roots absorb surge, and a boat webbed into them with a spider of fifteen lines can survive extraordinary winds. But the 2017 season rewrote the folklore. Irma's 160-knot core overwhelmed Paraquita Bay, where over 400 boats lay on the managed moorings, and turned the lagoon at St. Maarten into a wrecking yard. The lesson is not that holes fail; it is that a Category 5 direct hit overwhelms everything, and that a hole packed with poorly prepared boats is only as safe as its worst-secured neighbour.
Preparing a boat that stays afloat
If the boat rides it out in the water, on its own tackle or in a hole, the work list is unambiguous. Strip all canvas and running rigging; remove the boom if you can. Double or triple every line, with chafe gear at every contact point — chafe sinks more boats than breaking loads do. Set lines long, to spread surge rise; a storm surge of two to four metres is normal in a major hurricane. Use a spider web of lines into mangroves rather than relying on a single anchor; if anchoring, lay tandem or multiple anchors with all the chain you own. Seal every vent and hatch, shut every seacock, top up batteries and confirm the bilge pumps and float switches work, because the boat may be drinking rain and spray for twelve hours unattended. Then take your papers, take your crew, and leave. No boat is worth a life, and rule one of every official guidance is that people do not stay aboard.
The timeline when a storm is named
A workable countdown looks like this. At 96 hours from possible arrival: decide — haul, run or hole — and act on the decision; do not wait for certainty, because forecast cones at four days are 150-plus nautical miles wide and yard slots vanish first. At 72 hours: boat in position, canvas off, fuel and water topped, dinghy deflated or sunk on a mooring. At 48 hours: all lines and chafe gear set, anchors laid, mast windage minimised, documents and insurance photos backed up. At 24 hours: final check, hatch tape, neighbours' boats assessed (their failures become your collisions), crew ashore in solid shelter. Watching the NHC advisories every six hours is the rhythm of the season; complacency between storms is the enemy, because the average warning you can truly rely on is shorter than the work list.
Riding out the season elsewhere entirely
The cleanest strategy is absence. Many owners simply sail home: the May-to-June window from the Caribbean to the Azores and Europe, or up the US East Coast to the Chesapeake and New England, is a classic seasonal migration. Others ship the boat — yacht transport carriers run regular summer schedules from St. Thomas, Martinique and Palm Beach to the Mediterranean. And a growing number simply re-base for the summer: the southwest Caribbean, the Pacific coast of Panama, or a Mediterranean season while the charter boat earns nothing back home. Set against a potential named-storm deductible and months of anxiety, the cost of a one-way passage or a transport berth can look surprisingly rational.
Explore on the map
Whichever strategy fits your boat and budget, it begins with concrete places: the yard in Chaguaramas, the mangrove creek in Grenada, the marina that hauls catamarans, the bay everyone will run for when the cone tightens.
