More time on the water.

PWC covers blow off on the highway. Plastic snaps rip. The Wakeline Stay-On Cover Kit cinches your cover tight to the ski, then hooks a backup strap to the trailer — so the cover can stay on even after a snap has failed. Easy to hook on, and built to keep hardware off your gelcoat.

Covers that won’t stay on aren’t a small annoyance.

A loose cover can balloon at highway speed, flap against the gelcoat, tear at the snaps, or come off altogether. Replacing a factory Yamaha or Sea-Doo cover often costs around $300.

This kit is not a new cover. It holds the cover in two layers. First, labeled cinch straps tighten the hem to the hull so wind has a harder time getting underneath. Then one backup catch strap hooks to the trailer, so the cover has a backup if it works loose. Latching coated hooks and pads keep the hardware off your gelcoat. A snap kit and tape patch are in the bag if a snap has already ripped.

Cinch + Catch

How it works

Two layers. First, three labeled straps cinch the cover tight to the ski. Then one backup catch strap hooks to the trailer. Hook it on in the driveway. The pads and coated hooks are there so metal stays off your gelcoat.

Cinch

Bow cinch

Padded hooks clip under the rub rail and tighten the front of the cover to the hull, so wind has less room to get under the hem.

Cinch

Seat belly strap

A 10–12 ft strap runs over the seat and under the hull or between the trailer bunks. A neoprene sleeve sits on the seat, and a padded cover sits over the buckle.

Cinch

Stern cinch

A short strap tightens the rear hem — the spot where covers usually start to peel once you are up to speed.

Catch

Backup catch strap

One strap goes over the seat and down to the trailer frame. Latching vinyl-coated hooks click closed, so the cover has a backup if a cinch works loose.

Easy hook-on

Latching coated hooks click onto the rub rail or the trailer frame in one motion. The straps are labeled Bow, Seat, and Stern, so you are not guessing in the driveway.

Built not to scratch

Vinyl-coated hooks, neoprene sleeves, and padded buckle covers keep metal off gelcoat and keep straps from rubbing a hole in the cover. The card in the kit tells you to double-check that no buckle is sitting on the ski.

Works after a snap rips

The cinch straps hold the cover to the hull without depending on the cover’s own snaps or sewn loops. A snap kit and a Tenacious Tape patch are included so you can repair the tear, too.

What’s in the kit

Built first around Yamaha WaveRunner FX and FX Cruiser covers, including the 2025 FX Cruiser. The same cinch-and-catch method should also work on sit-down Sea-Doo and Kawasaki covers of similar size. Snap styles can vary by brand, so the included fasteners are a common marine repair set, not a guaranteed OEM-exact replacement.

Three labeled cinch straps

Bow, Seat, and Stern. The seat strap is 10–12 ft so it can run under the hull or between the bunks. The bow and stern straps cinch the hem to the ski.

Backup catch strap and latching hooks

One strap over the seat to the trailer frame, with vinyl-coated hooks that click closed. This is the backup if a cinch works loose.

Neoprene sleeves and buckle pads

Slide them wherever a strap crosses the seat, a hard edge, or a buckle, so nothing chews up the cover or sits on gelcoat.

Snap repair set and tool

Marine-grade stainless snap fasteners and a setting tool, so you can replace a ripped snap instead of retiring a good cover.

Tenacious Tape patch

Stick it inside the cover before you set a new snap, so the fabric has backing and is less likely to tear around the snap again.

Trailering card

A short driveway checklist: cinch the hem, hook the straps, keep buckles off the gelcoat, and re-check after the first 5–10 miles and at every stop.

Stand-up skis, heavily modified craft, or covers with unusual hardware may need a different strap length. If you are unsure, email a photo of your cover and ski before you pre-order.

Why it exists

Built by a WaveRunner owner who lost a cover on the first tow.

Ryan owns two 2025 Yamaha WaveRunner FX Cruisers. The first time he trailered one with the cover on, a plastic side snap ripped off and the cover blew off. Wakeline Supply Co. started as a name and a mark he already wanted to wear. The Stay-On Cover Kit is the first product because it is the problem he actually had. This Cinch + Catch layout was designed around his own FX.

Questions

Will it fit a Sea-Doo or Kawasaki?

The first run is specified around Yamaha WaveRunner FX and FX Cruiser covers, and the layout was designed on those skis. The straps and hooks are made for sit-down PWCs of similar size, so many Sea-Doo and Kawasaki covers should work the same way. Snap sizes are not identical across brands. The included fasteners are a standard marine set. If you are unsure, email a photo before you pre-order.

Will it scratch my ski or trailer?

Keeping hardware off the gelcoat is one of the design goals. The hooks are vinyl-coated and latch closed, and the kit includes neoprene sleeves and padded buckle covers. The trailering card tells you to make sure no buckle or hook is sitting on gelcoat before you drive. We have not built the first prototype yet, so this will be confirmed on Ryan’s own ski, and the pads can be adjusted if anything still sits where it shouldn’t.

Does it work if my snaps are already broken?

Yes. That is a big part of why the kit is designed this way. The cinch straps hold the cover to the hull and do not depend on the cover’s snaps or sewn-on loops. The catch strap hooks to the trailer as a backup. If a snap has already ripped, stick the Tenacious Tape patch on the inside of the cover and set a new snap with the included repair kit.

Can I trailer with this at highway speed?

The kit is designed for trailering at highway speed and for storage, not for use in the water. We have not highway-tested a finished kit yet — that is what the first prototype on Ryan’s own Yamaha FX is for. Until then, treat the catch strap as a backup, re-check the tension after the first 5–10 miles and at every stop, and do not drive with an open hook or a loose strap.

Is this a replacement cover?

No. It is a hold-down and protection kit for the cover you already have. If you need a new cover, buy one from your dealer or a cover maker, then use this kit so it stays on.

When will it ship?

About 3–4 weeks after the batch of 20 is reserved. Parts for this first run are ordered from U.S. retail suppliers (often a few days in transit), then each kit is assembled and packed by hand and shipped USPS Ground Advantage. If the batch fills slowly after pre-orders open, we will email everyone on the list with an update rather than sitting on a payment in silence.

What if the 20 kits sell out?

This first batch is capped at 20 so we can build them carefully and confirm fit. If it sells out, we will say so on this page and collect interest for a second run rather than taking money we cannot fulfill.

How do I install it?

A printed card in the kit walks through it. In short: tighten the hem elastic, fasten any snaps that still work, clip on the bow cinch, the seat belly strap (with pads over the seat), and the stern cinch, then attach the catch strap to the trailer with the latching hooks. Make sure no buckle is touching gelcoat. Re-check after the first 5–10 miles and at every stop.

Where do you ship?

The advertised postage is for the United States, via USPS Ground Advantage. If you are outside the U.S., write first and we will tell you whether a first-batch shipment is practical.
