About Stay Afloat Marine
When a leak strikes on the water, every second counts. Stay Afloat was built around a single, focused mission: give boaters a fast, reliable tool for stopping or slowing water intrusion before it becomes a crisis. The brand's flagship product — the Stay Afloat Instant Leak Plug & Sealant — has earned a loyal following among recreational boaters, commercial mariners, and marine safety professionals alike.
One Product, One Purpose — Done Right
Stay Afloat's sealant is a simple and versatile material designed specifically for stopping or slowing water leaks on boats and watercraft. What sets it apart from traditional marine sealants is its no-prep formula: it requires no mixing, measuring, or curing time. Instead, it is easily molded and applied by hand directly into holes, gaps, and cracks — whether the surface is wet or dry, above or below the waterline.
Applied in sufficient quantity, the sealant can stop or slow many types of leaks on its own. For larger breaches, it can be combined with supplemental materials such as wood or plastics to extend its effectiveness. Beyond plugging holes, the product also has secondary uses including sealing, lubricating, and waterproofing — making it a genuinely multi-purpose item to keep aboard.
Trusted in Emergency Situations
Stay Afloat has been utilized in numerous real-world rescue operations, valued for its immediate leak-stopping capabilities. The product does not harden, which means it can be removed easily once you reach the dock and are ready to make a permanent repair. Stay Afloat is transparent about this: the sealant is designed as an emergency and temporary measure, and the brand consistently recommends following up with a lasting fix as soon as conditions allow.
Compatible with fiberglass, wood, aluminum, plastics, and most other common hull materials, Stay Afloat is engineered to work across the wide variety of boat constructions found on the water today. It is not intended for use on inflatable chambers, and the brand provides clear guidance so users understand both the capabilities and the limitations of the product before relying on it.
A Smart Addition to Any Onboard Safety Kit
Marine safety experts often recommend carrying multiple types of damage control equipment, and Stay Afloat fits naturally into that layered approach. Compact enough to store in a gear bag or emergency kit, the 14 oz. container is sized for practical onboard use without taking up valuable space. Whether you're an experienced offshore sailor or a weekend lake boater, having a reliable emergency sealant on hand is simply smart seamanship — and Stay Afloat has made that peace of mind more accessible than ever.
