Buying Guide: How to Choose the Best Jet Ski Cover for Storage
Let’s be honest, finding the right cover for your jet ski isn’t the most thrilling part of ownership, but it’s one of the smartest things you can do. A good cover protects your investment from sun, rain, dust, and curious critters when you’re not riding. I’ve learned the hard way that not all covers are created equal. Here’s what I look for when choosing the best jet ski covers for storage.
First up is material. This is the most important factor. You want something tough, waterproof, and breathable. Polyester or canvas with a polyurethane or acrylic coating is a solid bet. Avoid cheap, non-breathable plastics at all costs—they trap moisture underneath and cause mold and mildew, which is a nightmare. Look for terms like “marine-grade” or “UV-resistant.” The material needs to withstand sun fading and degradation season after season.
Fit is next. A cover that’s too loose will flap in the wind, scratching your paint and potentially tearing. One that’s too tight is a struggle to put on. I always check if the cover is designed for my specific make and model, or at least for a very similar size class. A semi-custom fit is worth the extra cost. Features like elastic hems, adjustable straps, or buckle systems help secure it snugly. For trailers, look for a cover with a trailering strap or a separate, reinforced section to handle wind stress.
Durability features matter for long-term storage. Check the stitching—double-stitched or welded seams are much stronger. Reinforced areas at the handlebars, seat, and corners are spots that get a lot of stress. Vents are a small but critical feature; they allow air to circulate to prevent condensation buildup. Finally, consider the storage bag. A decent included bag makes off-season storage of the cover itself much easier.
My final piece of advice is to think about your primary use. Is it for indoor storage, outdoor under a carport, or full exposure to the elements? A heavy-duty, fully waterproof cover is non-negotiable for outdoor storage. For indoor use, a lighter, dust-proof cover might suffice. Investing in one of the best jet ski covers for storage saves you money on repairs and detailing down the line, keeping your ski ready for the next season of fun.
Frequently Asked Questions
Can I use a generic tarp instead of a fitted jet ski cover?
I strongly advise against it. While a tarp is cheap, it lacks breathability, leading to trapped moisture and mold growth on your seats and engine compartment. It also doesn’t fit snugly, so it will flap and scratch your jet ski’s hull and graphics. The abrasive material and poor fit can cause real damage. A purpose-built cover is designed to protect, not harm.
How often should I clean and re-waterproof my cover?
I try to clean mine at least twice a year: once before putting it into long-term storage and once when I take it out. Use a mild soap, soft brush, and rinse thoroughly. Let it dry completely before storing. Re-waterproofing depends on the material and how much sun it gets. If you notice water beading less effectively (it soaks in instead of rolling off), it’s time for a treatment. Use a product recommended for the cover’s fabric.
What’s the difference between a storage cover and a trailering cover?
This is a key distinction. A storage cover is for when your jet ski is sitting still. It focuses on weather protection and breathability. A trailering cover is built much tougher to withstand highway speeds and the constant whipping of wind. It has heavier reinforcements and stronger tie-down systems. Some covers are rated for both, but always check the manufacturer’s specifications. Using a storage cover for trailering can result in tears.
How do I prevent wind from getting under my cover during outdoor storage?
A good fit is the first defense. After that, use the integrated tie-down straps or a separate ratchet strap around the middle (use a soft towel underneath to prevent rubbing). If storing on a trailer, you can run a strap through the trailer frame and over the cover. Placing the jet ski in a sheltered spot, like against a wall or with the nose into the prevailing wind, also makes a big difference.
Are expensive covers really worth the money?
In my experience, yes, but with a caveat. You don’t always need the most expensive one, but you should avoid the absolute cheapest. A mid-range cover from a reputable marine brand often offers the best balance of price and protection. It safeguards your jet ski’s interior, paint, and electronics. Compared to the cost of repairing sun-damaged seats or a water-logged electrical system, a quality cover is a very wise investment.
