Waterproof Jet Ski Cover for Sea-doo 2011-2019 GTS GTI - Heavy Duty

In this review the Waterproof Jet Ski Cover for Sea-doo 2011-2019 GTS, GTS Rental, GTI, GTI SE and GTI Limited is judged primarily on fit and protection. It is aimed at owners who want a tailored, heavy-duty cover that resists sun and rain while stored on a trailer or in a driveway. The single biggest reason to consider it is the precise fit for the specified Sea-Doo model years coupled with robust 600D Oxford fabric and a PU coating that deliver practical waterproof protection and UV resistance.

Key Features

• Perfect Fit: Designed specifically for Sea-Doo 2011-2019 GTS and GTI families, the cover offers a snug profile that reduces flapping and improves long-term protection.
• Waterproof Construction: Made from 600D Oxford fabric with a PU coating rated to withstand 6-8 kPa of water pressure, it keeps most rain and spray off the hull and upholstery.
• Moisture Management: Dual rear vents help reduce trapped moisture under the cover, lowering the risk of mildew during storage.
• UV Protection and Durability: The fabric blocks harmful UV rays to prevent fading and cracking, and its tear-resistant weave holds up to regular use.
• Secure Fit and Access: Three adjustable straps, an elastic hem, zippered seat access and a rear storage box combine ease of use with a windproof hold on trailers.
• Visibility and Portability: Reflective strips improve low-light visibility and the cover packs into a portable storage bag for transport or offseason storage.

Who It's For

This cover is best for Sea-Doo owners of the 2011-2019 GTS and GTI series who need a tailored, heavy-duty solution for trailer or yard storage. It suits riders who value a tight fit, UV protection and straightforward access to the seat and rear storage while the craft remains covered.

It is not the right choice for owners of other Sea-Doo model years or different models, since fit is model-specific, and customers seeking a fully submersible or guaranteed leakproof solution for long-term marine immersion should consider purpose-built marine enclosures instead.
