Yachts in Florida operate on a different annual calendar than yachts almost anywhere else. The hurricane season runs nearly half the year. The water never gets cold enough to slow biofouling. UV is intense year round. And the high use season is short and concentrated, which means the maintenance window has to be precise.
This is the calendar our team runs for managed vessels across South Florida. Owners running their own programs can use it as a starting reference.
January through April: the use season
This is when the boats actually run. Owners are on board. Charter boats are working. The marinas are full. The marine trades are too booked to take new work without three to four weeks of lead time.
Maintenance during these months is reactive. The vessel needs to be ready every weekend, and any work that takes the boat off the water for more than two days is deferred unless safety critical. Bottom inspection is monthly, by an in-water diver. Anodes get checked and replaced if more than seventy percent consumed. Stainless and brightwork get weekly attention. Detailing happens between trips, not during them.
The single mistake owners make in these months is letting small problems compound. A water pump weeping in February becomes a water pump failure in April, and a failure in April means a boat sitting at the dock for the week the owner planned to host guests.
May: the transition month
May is the most important maintenance month in Florida. The use season is winding down. The marine trades have capacity. The hurricane season is six weeks away. Anything that needs to be done before the boat sits more, before storms arrive, and before the off-season slowdown begins, gets done in May.
The May agenda typically includes: annual haul-out, bottom paint refresh, propeller service, shaft and strut inspection, through-hull service, anode replacement, sea trial after splash, engine annual service, generator annual service, oil and filter changes, coolant exchange if due, raw water pump service, and lithium bank firmware updates where applicable.
June through November: hurricane season
The boat lives differently in these months. Even if hurricanes do not materialize, the planning footprint shapes everything.
The hurricane plan is filed with the marina, the insurer, and the captain. The plan specifies where the boat goes in a named storm: stay in the slip with extra lines, move to a hurricane hole, haul out, or move to an inland storage facility. Different policies require different actions, and the time to figure that out is May, not the morning of a watch.
Routine maintenance in these months is conservative. Engines should be exercised at least monthly, even if the boat is not being used, to keep seals and bearings in service. Generators should be run under load for at least an hour weekly. Batteries should be exercised, not just float charged. The boat that sits unstarted from June to November is a boat that will need a four figure recommissioning bill in December.
The monthly minimum
Regardless of season, every Florida-kept yacht needs these touches monthly at a minimum:
- Engine and generator start and run under load
- Battery state of health check
- Bilge pump function check, all chambers
- Fire suppression visual inspection
- Through-hull and seacock exercise
- Exterior wash and chamois dry
- Interior climate check, dehumidifier or AC operation
- Bottom and running gear visual by in-water diver
None of these take long individually. Skipping them, however, compounds. A bilge pump that has not been tested in three months will not move water in a storm. A battery left at low charge for the same period will not start an engine. An exhaust elbow that was not inspected at the last quarterly will be the failure that strands the boat off Government Cut.
Annual haul-out: when and why
The annual haul in Florida should be scheduled for May or for the first week of December. Those are the windows when the yards have capacity and the weather is workable.
What happens on a proper haul: pressure wash hull, scrape biofouling, inspect bottom paint for adhesion, recoat as needed (typically every two seasons rather than annually), inspect propeller bearings and replace if due, inspect cutless bearings and replace if due, check shaft for run-out, service through-hulls, replace anodes, inspect rudder bearings and stuffing box, inspect prop shaft seals.
A haul that takes three days is normal. A haul that takes ten days is the boat telling you something. Owners should be wary of yards that quote three days and consistently take ten.
Insurance-driven inspections
Insurance carriers in Florida now routinely require: a current survey on any vessel above a value threshold, typically renewed every five years. A documented hurricane plan. A captain endorsement or named captain on hulls above 50 feet. Annual engine and bottom inspections. Lithium battery survey for any vessel with a retrofit bank.
Carrier requirements are evolving fast in 2026 as Florida hurricane losses harden the market. Owners should expect more, not less, on the inspection side over the next several renewal cycles. The boats that pre-comply renew at preferred rates. The boats that miss requirements are non-renewed in months they cannot afford to be.
The compounding effect
A Florida yacht that runs this calendar properly for ten years sells at a premium of fifteen to twenty percent over a comparable vessel that did not. The maintenance log is what does it. Future buyers read the binder, see the discipline, and pay for it.
We maintain this calendar across our managed fleet. Owners receive a photographic monthly report. The boat is ready when they are.
