A North Miami Beach angler runs his center console east past the Gulf Stream on a calm Sunday, chasing a weed line that keeps moving offshore. When an engine overheats and he calls for a tow, he is about eighty miles out. On Monday he learns that his recreational policy covers him within seventy-five miles of the coast. The tow, and anything that happened past that line, is his to pay.
Every marine policy defines the waters it responds in. Cross that boundary and coverage can be suspended entirely, not reduced or subjected to a higher deductible, but suspended for as long as you are outside it. For South Florida owners this matters more than almost anywhere in the country. A run to Bimini takes a morning and the Abacos a weekend, so the Bahamas feel like an extension of the local cruising ground, and a great many policies do not see it that way.
Three Ways Limits Get Written
Navigation territory appears on your declarations page or in a schedule attached to it, and it takes one of three forms. The first is named waters, where the policy lists the areas covered, such as “inland and coastal waters of the continental United States,” specific states or specific bodies of water, and anything unnamed is outside. The second is a distance from shore, common on recreational policies, where coverage applies within a stated number of miles of the coast, frequently fifty, seventy-five or a hundred, and beyond that line you are uninsured.
The third is coordinates. Yacht and larger vessel policies typically define a box by latitude and longitude, which is precise and unforgiving, since a boat one mile outside the stated boundary is outside it. Find out which form your policy uses before assuming what it permits. Owners are frequently surprised, particularly by mileage limits they never noticed.
The Mileage Trap
A distance-from-shore limit sounds generous until you map it against where you actually go. Offshore fishing runs can exceed a seventy-five-mile limit without the boat ever feeling far out, and a breakdown eighty miles offshore under a seventy-five-mile policy is an uninsured towing bill, with offshore tows priced accordingly.
The Bahamas are a separate trap. Bimini sits only about fifty miles from Miami, but a mileage limit measured from the U.S. coast does not make foreign waters covered. If the policy’s territory is limited to U.S. coastal waters, the islands are outside it no matter how close they are. If your policy carries a mileage limit and you fish offshore or run to the islands, that is worth resolving before the next trip rather than after one.
The Bahamas
Most U.S. recreational policies do not include the Bahamas without an extension. Some carriers add it readily by endorsement, sometimes at little or no additional premium and sometimes with seasonal restrictions, while others will not extend at all, which means the trip requires a different policy.
Confirm three things before departure. First, make sure the extension is endorsed in writing, because a verbal agreement with an agent is not coverage; get the endorsement issued and confirm it appears on the policy documents before you leave the dock. Second, find out what the extension actually includes. Hull and liability usually travel, but towing and salvage abroad frequently do not, or respond differently, and a tow from Bimini or the Abacos is a different proposition than one in Biscayne Bay. Third, check whether it is seasonally limited, since some extensions exclude the hurricane months entirely or apply different terms during them.
Separately from insurance, Bahamian customs requires a cruising permit and clearance on arrival, and marinas there commonly ask for proof of insurance with specific liability limits before assigning a slip.
The Caribbean
Beyond the Bahamas, coverage generally moves out of the standard market. Caribbean cruising is written by specialist marine underwriters and Lloyd’s syndicates rather than the carriers that handle Florida recreational business, and premiums in that market commonly run in the range of one to one and a half percent of agreed value a year, with named windstorm terms layered on top.
Some regions carry materially worse terms. Underwriters in this market have been known to double deductibles or exclude theft outright in certain waters unless the vessel is moored in a commercial marina agreed in writing beforehand, and because political and security conditions drive those terms, they change. Certain vessel types are difficult or impossible to place for extended cruising at all, and single-handed operation typically requires written approval. Cuba deserves separate mention, since U.S. sanctions law creates complications independent of insurance, and a policy extension does not resolve them.
The Hurricane Box
This is the seasonal overlay that catches owners who thought their geography question was settled. There is no single industry-wide hurricane box, and each underwriter draws its own on the policy, but the concept is consistent: a defined named storm risk area covering coastal Florida, the Gulf, the Bahamas and much of the Caribbean, where different rules apply between June 1 and November 30.
Being inside the box during the season triggers two things. The first is a signed hurricane plan, which is not a formality. The plan states where the vessel will be and what will be done when a storm threatens, and complying with it is a condition of named windstorm coverage. Claims in this market are denied most often not because the damage was small, but because the vessel was inside the box during the season without a filed plan or without documentation showing the plan was carried out.
The second is a named windstorm deductible, which is separate from the standard deductible and substantially higher. It is frequently a percentage of agreed value rather than a flat sum, and in the yacht market it commonly reaches ten percent, so on a vessel insured for five hundred thousand dollars, the deductible is fifty thousand. The trigger for a named storm is generally NOAA’s official naming rather than an underwriter’s judgment, which at least makes it objective. Owners who move their vessels out of the box for the season, north of a stated latitude or to a location the carrier accepts, frequently earn meaningful lay-up credits, which is a real lever for anyone whose cruising schedule allows it.

What No Extension Covers
Some exclusions travel with you regardless of territory. War, capture, seizure, detainment and confiscation, piracy and the taking of the vessel, and kidnap and ransom all require specialist coverage arranged separately. For most Florida owners cruising the Bahamas these are academic, but for anyone going further, they are not.
Get It in Writing Before You Leave
The single most common failure here is sequence. An owner calls the agent, describes the trip, hears that it should be fine and leaves, and the endorsement is never issued, or is issued after departure. An extension agreed verbally and never documented is not coverage, and a claim from a passage that began before the endorsement took effect is a claim outside the navigation limits. Ask for the endorsement, confirm you have received it and read the effective date.
Before Any Passage Outside Florida Waters
Six questions cover it:
-
What does my policy state as the navigation territory, and in what form: named waters, mileage or coordinates?
-
Does my planned route stay inside it at every point, including the crossing?
-
If not, is an extension available from this carrier, and has it been issued in writing?
-
Does the extension include towing and salvage in those waters, or only hull and liability?
-
Am I inside a hurricane box during the season, and if so, is a signed plan on file?
-
Do the marinas where I plan to stay require higher liability limits than I carry?

Frequently Asked Questions
Does my Florida boat policy cover the Bahamas?
Usually not without an extension. Some carriers add it by endorsement, some restrict it seasonally and some will not extend at all.
What happens if I cross outside my navigation limits?
Coverage can be suspended for as long as you are outside them, and a claim arising while you are outside the stated territory is generally denied in full, regardless of cause.
How far offshore am I covered?
It depends entirely on your policy. Recreational policies commonly cap coverage at a stated distance from shore, so check the number rather than assuming.
What is the hurricane box?
A defined named storm risk area that each underwriter draws on its own policies, generally covering coastal Florida, the Gulf, the Bahamas and the Caribbean. Being inside it during the season triggers hurricane plan requirements and a higher named windstorm deductible.
