Float Care and Storage

The end-of-season routine

1. 1.Rinse with fresh water. Lake silt is abrasive and chlorine degrades vinyl. Both need to come off before storage, inside as well as out for anything with a cavity.
2. 2.Deflate fully. A float stored inflated is a float under constant stress at every seam, and internal pressure changes with temperature all winter.
3. 3.Dry completely — inside and out. Trapped water grows mold that stains permanently and smells. Leave valves open and stand floats on edge for a day.
4. 4.Dust with talc if you have it. It stops folded vinyl surfaces sticking to each other, which is what causes tearing when you unfold in spring.
5. 5.Fold loosely, do not crease. Set creases become split lines. Roll rather than fold where you can.
6. 6.Store cool, dark and dry, off a concrete floor. Out of direct sun, away from anything sharp, and away from rodents — which genuinely do chew vinyl.

That routine is the whole difference between a float that lives three seasons and one that is bin-bound in May. It takes about twenty minutes for a full set.

The inflation mistake everybody makes

Do not inflate to drum-tight. Air expands as it warms, and a float filled hard in cool morning air is under significantly more pressure by midday in direct sun. That is when seams split, and it is the single most common cause of a burst float or tube.

Inflate until firm with a little give when you press it — you should be able to depress the surface slightly with a thumb. Check it through the day and release a little air if it has gone hard. On a towable tube this matters even more, because it is also under load at speed.

And inflate chambers in the order the manufacturer specifies on multi-chamber floats. Doing it out of order distorts the shape and puts uneven load on the internal baffles.

How to patch vinyl properly

1. 1.Find the leak. Inflate, then brush soapy water over the surface and watch for bubbles. For a slow leak, submerge a section at a time.
2. 2.Mark it with a pen while the float is still wet, because a pinhole is almost impossible to find twice.
3. 3.Deflate and clean the area with fresh water, then dry it completely. Glue will not bond to a damp or silty surface.
4. 4.Round the corners of the patch. Square corners peel. Cut the patch at least half an inch larger than the hole all round.
5. 5.Apply glue to both the patch and the float, thinly, and let it become tacky before pressing them together — that is how vinyl cement is designed to work.
6. 6.Press firmly and weight it flat, then leave it to cure fully. Most kits want several hours, and some want a full day. This is the step people rush and it is the step that decides whether the patch holds.

Repairs at the lake, when the glue has no time to cure

A proper vinyl patch needs hours to cure, and a leak found at eleven in the morning does not have hours. Two things genuinely work as a same-day fix.

A self-adhesive vinyl patch, sold in the same kits as the glue-on kind. It bonds on contact, it works on a surface dried with a towel, and it will hold for the rest of the day and often for the rest of the season. It is the reason to buy a kit that contains both kinds.

Waterproof repair tape over a dried surface. Less elegant, entirely effective as a stopgap, and worth keeping in the car. Neither is a substitute for a cured glue patch at the end of the season — do that one properly when you have time.

What does not work: applying glue to a wet surface, or patching while the float is inflated. The seam is under tension and the patch peels from the edge within the hour.

Storing a tow rope and harness

The rope is the part of a towing setup most likely to fail and the part least likely to be looked after. Three habits:

• •Dry it before storing. A rope coiled damp in a locker degrades and mildews, and mildew hides the fraying you are trying to spot.
• •Coil it loosely, never knotted. A knot in a tow rope substantially reduces its strength, and a knot left in over winter sets a permanent weak point.
• •Inspect at the start of each season along the whole length, and particularly at the loops and thimbles where load concentrates. Fraying there means replace the rope, not repair it.

And match the rope's rating to the tube's rider count, which is covered in how to choose a towable tube. A rope carried over from a one-rider tube is under-rated the moment you buy a three-rider one.

Looking after a foam mat

Foam mats need less, but not nothing. UV is the enemy: the outer membrane degrades under prolonged direct sun, so store the mat shaded or covered rather than leaving it on a dock all summer. Rinse the lake water off at the end of the season.

Store it flat or loosely rolled, never folded sharply — a hard crease in closed-cell foam can permanently compress the cells along the fold. If it lives outdoors, a tarp over it does most of the work.

Looking after a towable tube

The cover and the bladder are separate parts and both need attention. Rinse fresh water through between the cover and the bladder if you have been in silty or weedy water — grit trapped in there abrades the bladder from the outside, which is a failure you cannot see coming.

Dry both before storage, deflate fully, and store the cover loose rather than tightly rolled around the bladder. Inspect the tow point and the stitching around it at the start of each season; that is where load concentrates and where failures start.

What we recommend

If you want to stop thinking about any of this, buy foam for your main platform — it cannot puncture, and the care routine is little more than keeping it out of the sun. For inflatables, the twenty-minute end-of-season routine above is the highest-return maintenance in this whole category.
