SENTRY Features


    Sausage boat fenders have been around for decades and, let’s face it, they’re difficult to use on smaller boats. They just haven’t adapted to meet the needs of boaters today. Sport boats no longer have flat sides, handrails, and high-waisted rub rails. This makes it extremely difficult to position a protective fender between a boat and dock where protection is needed most. With this in mind, we set out to create a better fender that looks great and keeps your boat protected, fast.


    SENTRY’s innovative hanging system enables easy positioning on a boat or dock to provide the most protection possible both above and below the rub rail, unlike traditional fenders.*Patents pending. Note: SENTRY Fenders are designed for day use only. They’re not intended for mooring applications or storage. Don’t leave your boat unattended for long periods.


    SENTRY Fenders have a hanging point that’s lower than traditional fenders. This allows SENTRY to hang at an angle that aligns with the contour of your boat’s hull. This keeps SENTRY from getting caught on top of the dock. It also looks better.


    No ropes, no hassle. Traditional fender ropes get tangled and moldy. SENTRY uses an integrated DRYLINE strap system that easily attaches to boat cleats and docks, always stays dry, and resists mold. The compact profile of the strap also leaves more space on the cleat for easily attaching dock lines.


    The large opening in the front face allows dock lines to pass through in situations where the fender covers the boat cleat. This keeps the lines straight and SENTRY aligned and ready for action.

    SENTRY comes with an extra-long strap out of the box to make looping it over higher attachment locations like towers and grab rails super simple. If your cleats are already in a great spot for hanging SENTRY, you can trim the strap to keep things tidy.


    An innovative locking mechanism makes it easy to position and reposition SENTRY on a boat or dock for unrivaled protection both above and below the rub rail. The no-roll design and broad shoulder surfaces keep SENTRY in place until you’re ready to get moving. *Patents pending.


    SENTRY Fenders are molded from XL EXTRALIGHT® – a revolutionary closed-cell foam that’s lightweight and extremely durable. This patented material is non-marking, non-staining, and completely waterproof. It's easy to clean, salt and chemical resistant, and resists fading from the sun's harmful UV rays.
