In South Florida, storing boat cushions is about heat, humidity and hurricanes, not cold. Get them clean and fully dry, keep them somewhere ventilated and out of the worst heat, and decide before June where they go when a storm is named.
Most of the storage advice written for boat owners assumes a winter: haul out in the fall, shrink-wrap, wait for spring. That is not how boats live here. A boat here can be used in any month, and when one does sit, it often sits in a hot slip or on a lift for a few weeks while the owner is away. The cushions face a different set of threats, and they need a different plan.
There is no winter, so plan for the weeks the boat sits
The dangerous stretch for a Florida interior is not a season. It is any period of a few weeks when nobody is aboard: summer travel, a busy month at work, waiting on a mechanic. Heat builds, moisture has nowhere to go, and nobody is there to wipe off the sunscreen from the last trip.
So treat any planned break of more than a couple of weeks as "storage", and do the same few things every time.
Clean before it sits, not after
Sunbrella's end-of-season advice is to clean the boat thoroughly, inside and out, before putting it away, and its reason applies here as much as anywhere: its fabrics do not promote mildew, but mildew may grow on dirt and other foreign substances that are not removed. A cushion stored dirty is a cushion stored with food for mildew.
Wash the vinyl with a mild soap solution, rinse until no soap is left, and let it air dry. Our marine vinyl care guide has each maker's mix. Spradling also says to clean any stain within 24 hours, so deal with the last trip's spills before the boat is left, not when you come back.
Dry means dry all the way through
The surface can feel dry while the foam underneath is still holding water. Give cushions a full day in moving air, standing on edge so water can drain out of the bottom seam, before anything covers them.
Never snap a cover down over damp cushions. It is one of the few things we ask every client to treat as a rule, because it turns a cover from protection into a humid box.
If your cushions were built with an open-cell, quick-draining foam, they shed water faster, but they still need air. We explain the foam side in what is under the cover.
Where to keep them
If the cushions come off the boat:
- Somewhere air-conditioned or at least shaded and ventilated is best. A closed garage or a shed in a Florida summer gets very hot, and heat is what speeds up discoloration in vinyl. Marine Fabricator reported testing that pointed to heat buildup of 150 degrees F or higher as the key factor.
- Stand them on edge or lay them flat with nothing stacked on top, so the foam keeps its shape.
- Keep them up off the floor, on a shelf or a rack.
- Use breathable covers or clean cotton sheets, not sealed plastic bags. Anything that traps moisture traps it against the cushion.
If the cushions stay aboard, Spradling's own advice to owners is the right starting point: cover the boat when it is not in use, allow venting so moisture is not trapped, do not leave wet towels, swimsuits or foul-weather gear stowed inside, open lockers and cabinets to let air move, and use moisture-absorbing desiccants. Ask someone to lift the cover and look every couple of weeks if you will be away a while.
Hurricane season is the real off-season
The Atlantic hurricane season runs from June 1 to November 30, according to the National Hurricane Center, with most activity between mid-August and mid-October. That overlaps the height of summer, when a boat left sitting takes the most heat. So the storage plan and the storm plan should be one plan, written down before June.
Miami-Dade County's emergency guidance for boat owners is direct: remove all moveable equipment such as canvas, sails, dinghies, radios, cushions and biminis. Cushions and canvas left aboard catch the wind and can be torn away. Plan to take the canvas down well before the wind arrives, not as it starts.
The county also notes that trailer boats should be out of the water and secured at least 48 hours before expected landfall, that marinas close once sustained winds reach 39 mph, and that bridges typically lock down at least eight hours before those winds are forecast. The practical meaning is that your window to get cushions and canvas off the boat closes earlier than the storm does.
What helps on the day:
- Know where every piece goes. A garage corner, a spare room, a storage unit. Decide it now.
- Photograph the boat with everything in place before you strip it. It helps with putting it back and with any insurance conversation later.
- Bag and label the canvas by panel, and keep the fasteners with them.
- Store the cushions as above: dry, ventilated, off the floor.
If your boat is with us when a storm is named
We will be straight about this, because it is in our signed terms. Clause 4 says: "In the event of a named storm, tropical storm warning/watch, or hurricane warning/watch issued by the National Hurricane Center affecting the service location, the Client is fully responsible for securing, removing, or relocating their vessel. Rivers Refined, LLC does not assume responsibility for hurricane preparation, vessel evacuation, or damage resulting from Acts of God."
The same clause asks that the vessel be insured under a comprehensive marine hull and liability policy, which serves as primary coverage. If a job of yours is scheduled during hurricane season, talk to us about timing when we plan it, and have your own storm plan ready for the boat. Our FAQ covers how the boat travels to and from us.
After the storm, or after a long sit
When the cushions go back on, look before you sit:
- Check seams and stitching for anything that has pulled or opened.
- Look for mildew spots and treat them early, with diluted bleach at the maker's ratio and a thorough rinse, never at full strength.
- Press the cushion. A soggy feel or a sour smell means water got into the foam.
- Watch for pink that will not wipe off. That comes from inside the cushion, and we explain it in pink stains on marine vinyl.
Our craftsmanship warranty is a "two (2) year limited warranty covering failures in stitching, seam binding, and direct installation craftsmanship from the date of final delivery. This warranty is transferable: if the vessel is sold during the warranty period, the warranty passes to the new owner for the time remaining, measured from the original date of final delivery." It excludes "damage resulting from commercial overuse, neglect, improper washing/ cleaning (including the use of harsh bleach or high-pressure washers)" and general wear and tear, and storm damage falls under clause 4 above. Manufacturer material warranties are passed through to you. Budget-tier work carries no craftsmanship warranty. The terms page has the exact wording.
If the cushions did not make it
Water-logged foam, split seams, mildew that has set in: send us a few photos of the cushions and the boat, and we price the repair or replacement from them.
Send us photos of the boat and we will price it from those.
