Clean, Deflate, Store: The Off-Season Routine
A slower season is the best time to take care of the gear that took care of your boat all year. Here's the routine that keeps it ready for the first warm weekend.
It's the first cool Saturday of the season. The boat is back in its slip after one last run, and the dock box is overflowing: dock lines stiff with salt, a cooler you're afraid to open, life jackets still damp, and bumpers that have been hanging over the side since Memorial Day.
It's tempting to shut the lid and deal with it in spring. But spring-you will open that box to mildew, crusted salt, and gear that didn't make it. An afternoon now saves a lot of replacing later.
Here's the routine, start to finish.
Bookmark this one. It's the checklist you'll want again next fall.
Step 1: Pull everything out and take inventory
Empty the dock box, lockers, and cabin storage onto the dock. You can't care for gear you can't see.
As you go, sort everything into three piles:
Keep and clean: gear in good shape that just needs attention.
Repair: items with a fixable problem, like a chafed line or a loose fitting.
Replace: anything cracked, frayed through, or past saving.
Write down what's in the replace pile now, while you're looking at it. That list is your spring shopping list, and you'll thank yourself in March.

Step 2: Wash off the season
Salt, sunscreen, fish slime, and pollen all break down gear faster when they sit. Give everything a freshwater rinse, then a gentle wash with mild soap and a soft brush.
Dock lines: Soak them in a bucket of fresh water with a little mild soap, work the salt out by hand, and rinse well. Lines that stay stiff after washing are telling you something. Check them closely for chafe.
Life jackets: Rinse, then hang them to dry out of direct sun. Test buckles and straps while you're at it.
Bumpers: Wash with mild soap and water and a soft cloth or brush, paying attention to the D-rings and the valve area where grime collects. Skip harsh solvents and abrasive cleaners, which can wear on PVC.
Coolers and bins: Wash, rinse, and prop them open so they air out completely.
Share this with the friend whose dock box you've been afraid to open. You know who it is.
Step 3: Dry everything completely
This is the step most people rush, and it's the one that matters most. Gear packed away damp turns into a mildew problem in a matter of weeks, especially in a humid climate.
Lay everything out on the dock or in the cockpit on a dry, breezy day. Flip items halfway through. Don't pack anything until it's dry inside and out, including the folds, seams, and pockets.
Step 4: Inspect and repair while it's in front of you
With everything clean and dry, small problems are easy to spot and easy to fix.
Lines: Look for flattened, glazed, or fuzzy sections, which are signs of chafe. Whip or melt any frayed ends.
Hardware: Check snaps, clips, and shackles for corrosion. A drop of lubricant now keeps them from seizing over winter.
Bumpers: Inflate each one to firm and let it sit for a few hours. If it softens, use the repair kit that came in the box to patch any small leak now, so it's ready when you need it. Check that the D-rings are secure and the valve seats cleanly.

Step 5: Stow it small and stow it smart
This is where gear that takes up less space pays off. Deflate your bumpers fully, roll them from the end opposite the valve to push the remaining air out, and they'll fit in a locker or bin with room to spare. A 12-foot bumper that protected a whole dock all summer rolls up into a bundle you can carry under one arm.
A few storage rules for everything:
Keep it out of direct sun and heat. UV and heat age PVC, rubber, and line faster than use does.
Keep it off bare concrete and away from anything sharp.
Store it loose, not crushed. Don't pile heavy gear on top of rolled bumpers or coiled lines.
Label your bins. "Dock lines," "bumpers," "safety gear." Spring-you will be grateful.
Still using bulky foam that eats half your locker? That's exactly the problem we built Big Bumper to solve.

Step 6: Keep a "first day back" kit ready
Before you close the lockers, set aside a small bin with what you'll need on your first day back on the water: one set of clean dock lines, two bumpers ready to inflate, and your safety gear. When the first warm weekend comes, you can grab one bin and go instead of digging through everything.

Boating through the winter?
If you're on the Gulf or anywhere else the season never really ends, you don't have to stow everything at once. Rotate through this routine one locker at a time, and keep a clean, dry set of gear aboard while the rest gets its turn.
Protects big. Stows small.
The best gear works hard all season and gets out of the way when the season's over. Big Bumper inflates in under a minute when you need it and rolls up small when you don't.
