What This Is
A custom jet ski cover is a made-to-measure waterproof cover cut to the exact shape of your ski — hull, seat, handlebars, and all. A jet ski takes the weather from every side. Sun on the seat all day. Rain sitting in the footwell. Salt in the engine bay. Weeks on the trailer or at the dock between rides. The seat and the deck are the most exposed surfaces on the machine — and the most visible signs of neglect when left uncovered.
A jet ski cover is cut to the measurements of your ski — not a size category it approximately fits. Length nose to tail, width at the widest point of the hull, height from the deck to the top of the bars. Sea-Doo, Yamaha WaveRunner, Kawasaki, any make, stand-up or sit-down — we build to whatever you own. Every Kuvr jet ski cover is made to order, and backed by our First Time Fit Guarantee.
This is part of our range of vehicle, jet ski and boat covers. If you keep a center console alongside the ski, we make a custom cover for that too — cut to the exact dimensions of your console, not a generic size. See our custom center console boat covers. But for the ski itself — on the trailer, at the dock, or over winter — this is the cover made for it.
Why a Universal Jet Ski Cover Never Fits Right
A Sea-Doo GTX, a Yamaha VX WaveRunner, and a Kawasaki Ultra are three different shapes — different lengths, different widths, different handlebar heights. A cover made to an average fits none of them properly.
Search jetski cover or jetski covers and every result is the same bag of generic sizes. A cover cut too big flaps in the wind, catches on the trailer, and pools rain in the slack. A cover cut too small gets dragged tight over the bars and splits at the seams within a season. Oversized or undersized, both let UV onto the one surface that shows it first: the seat.
That is the real cost of a loose cover. The vinyl seat bleaches and cracks where the fabric does not sit flat. Moisture gets trapped underneath and never dries. Mould takes hold on the upholstery — that's the visible damage. The less visible damage is water in the engine bay: corroded electrics, corroded components, repair bills that make a proper cover look very cheap in hindsight. There's a right way to cover a jet ski and a wrong way. The difference: cut to the machine, or cut to a size chart.
Custom jet ski covers only earn their keep when they are cut to the machine. Personal watercraft covers are the same story — PWC, jet ski, whatever you call it, the cover only works when it follows the actual shape of your ski. Not the nearest available size.
What It Protects
Which Ski Do You Ride?
Which Ski Do You Ride?
These are three of the most common brands, not the limit of what we cover. Whatever you ride, we cut to your exact make and model — sit-down or stand-up.
Sea-Doo Covers
Sea-Doo is the world's best-selling personal watercraft brand, and no two families share a footprint. A GTI, a GTX, an RXT, and a Spark are all different lengths and deck heights. Our Sea-Doo covers are cut to the exact model you ride — the tall touring seat on a GTX, the compact hull of a Spark. Give us the model and your measurements, and we cut to it — so the cover sits tight over the seat and clears the mirrors without bagging at the base.
Yamaha WaveRunner Covers
Yamaha WaveRunner has been on the water for decades — more model families than any other brand. A VX, an FX, and an EX are different lengths, different widths, different deck heights. One size cannot cover all three. A standard WaveRunner cover is sized to a category, not your machine. Our Yamaha WaveRunner covers are cut to your exact model, whether you call it a WaveRunner or a Yamaha jet ski. Handlebar height, seat length, and jet ski width all come off your machine, not an average of the range.
Kawasaki Jet Ski Covers
Kawasaki is the brand that gave the jet ski its name. The Ultra and STX sit-down models and the SX-R stand-up are not interchangeable — different lengths, different widths, different deck heights entirely. The SX-R stand-up in particular is a shape no universal cover comes close to. Give us your model and measurements and we cut to it — sit-down or stand-up.
What Sun, Rain and Trailering Do to an Uncovered Ski
A ski stored uncovered loses value measurably faster than one kept under a cover cut to fit. The seat bleaches in the first season. UV fade on the hull and graphics is permanent. Salt keeps working in the engine bay between rides. Here is what that looks like in practice:

How This Jet Ski Cover Is Different
-
01
Cut to Your Exact Make and Model
Length nose to tail, width at the widest point of the hull, height from the deck to the top of the handlebars. We cut to your exact measurements — not a size category your ski approximately fits. The measurements matter even once you've named the model. A Sea-Doo GTX Sport is a different length to a GTX Limited. An added rack or taller windshield changes the profile further. Tell us exactly what you have and we build to that ski — not the average of everything that shares its name.

02
100% Waterproof, With Vents That Let Moisture Out
Two fabric options: NylonSafe® for home and light commercial use, PVCArmour® for high-exposure environments. Both use HydroLok® heat-sealed seaming — no water enters through the seam lines. Each seam is stitched and sealed internally so water cannot enter through the seam lines. The cover is fully waterproof — and integrated air vents let trapped moisture escape, so damp air does not sit against the seat. UV-stabilised throughout, rated for salt air, dock, and trailer.
-
03
Trailerable — Stays On at Highway Speed
A hem cut to your ski's exact perimeter leaves no loose fabric for wind to catch. An integrated securing system — drawstring hem and straps — locks the cover to the ski. No flapping, no pooling, no bleached seat. It holds on the trailer at highway speed, at the dock in a blow, and through the off-season as a jet ski winter cover.
-
04
Made Once. Protects for Years.
Reinforced at every stress point. A jet ski cover made to your exact dimensions does not need replacing each season. The construction handles sustained UV, salt spray, trailer miles, and years of outdoor storage without degrading — which is why a made-to-model cover outlasts an off-the-shelf one several times over.
Every cover starts from your measurements and a design we send you to approve before anything is cut. Keep the boat covered too with a custom center console boat cover, made the same way.
When You Need a Custom Jet Ski Cover
Not everyone needs this. Here is how to tell which side you are on.
This cover is right for you if:
Your ski lives outdoors — on a trailer in the driveway, on a lift at the dock, or stored uncovered between rides. It takes sun, rain, and salt when you are not on it.
You have had a universal cover flap loose, pool water, or bleach the seat where it did not sit flat. You want one that actually fits.
You tow the ski and need a cover that stays put at highway speed instead of chafing the hull the whole way there.
You don't need this if:
Your ski is stored indoors, out of the sun and weather, whenever it is not on the water.
You replace a cheap universal cover every season and are happy with that arrangement.
You need something shipped today and fit does not matter.
