Protects better than PVC fenders.

They cover more area and actually stay where you need them. With my current fenders, I was always adjusting or repositioning. These just handle it without the extra effort.

Confidence pulling in.

I don’t second guess docking anymore. I know the boat’s protected before I even get close. That peace of mind makes a big difference, especially in tight spots. I don’t second guess docking anymore.

No marks, no problems.

They’re soft on the boat but still really protective. I haven’t had any issues with scuffs or marks. That alone makes them worth it to me. They’re soft on the boat but still really protective.

Wouldn’t go back.

After switching to foam, I’d never go back to traditional fenders. The difference is noticeable right away. It’s just a better overall experience on the water.

Set it once. It stays.

Once you set them, they don’t move. There’s no slipping or constant adjusting like I was used to before. It just stays where you put it and does its job. Once you set them, they don’t move.

No. Traditional PVC fenders mark hulls — that's just the reality of the material. CANNON is different. Built from XL Extralight, a patented closed-cell foam engineered for marine applications, it makes contact with your hull cleanly and leaves nothing behind. That said, as with any fender, keeping it clean and free of grit or debris is always good practice.

CANNON is designed for boats with significant freeboard — you'll want at least 30 inches of vertical clearance from the water line to the attachment point for the fender to hang and perform correctly. The fender itself is 8 inches in diameter and about 24 inches tall, which provides solid offset for larger hulls. You'll typically find that kind of freeboard on boats in the 25–32 ft range, though it's really the height of your freeboard that matters more than the length of the boat.

If your freeboard is on the lower side or the spot you need protection is closer to the waterline — like the stern corners of larger boats — SENTRY, ICON, or DYMON may be a better fit depending on your setup.

Simple. Take the loop end and pass it around a cleat, through a cleat, around a rail — whatever you've got. Then push the button knot through the loop. That's it. It's on, it's locked, and it's not coming off unless you take it off yourself.

No. CANNON Fenders use DREADKNOT, a tension-based locking principle trusted in climbing and rescue applications for a century — the more load it takes, the more securely it holds. Set your height and it stays there through wave action, current, and contact. But when you decide to adjust, it slides easily. Locked when you need it, free when you want it.

A pendant fender like CANNON is the right call when you need protection lower on the hull — hanging down from the rail with room to work. The longer the freeboard, the better it performs.

Where pendant fenders can get tricky is right up at the rub rail, where they can get pinched or sit at an awkward angle. That's exactly what SENTRY and DYMON are designed for — protection at the rail, rather than below it.

For most boats with good freeboard, a pendant is precisely what you need. And CANNON is the best version of it.

Yes — CANNON is Phender Pro ready right out of the box. Just remove the soft shackle, pass the loop through your hardware, and you're connected. It takes seconds and works seamlessly if you already have the full Phender Pro system.

We stand behind everything we make. CANNON comes with a 30-day worry-free return window and is backed by a 3-year warranty. If for any reason it doesn't work out, we'll make it right. Simple as that.
