5 Reasons Your Boat Fenders Are Letting You Down

Excellent 4.8

"PVC had a good run."

— Kris 05/1/26

1.

They deflate.

You walk down the dock, step aboard, and there it is – your fender pancaked flat against the hull. At some point it just let go. Now you're pumping it up dockside like it's a pool toy. Where was that pump again?

This isn't bad luck. It's just how inflatable fenders work. PVC has valves, and valves crack and then leak. CANNON is closed-cell foam. No air inside means nothing to lose — same protection on day one as day one thousand.

2.

Nothing’s changed.

The round pendant fender has been around since the 1950s. Polyform. Taylor Made. PVC and a valve. Nobody really questioned it — it was just the thing you grabbed off the peg at the marina because that's what everyone uses.

CANNON is what happens when someone finally decides that's not good enough. Same classic round shape. Better in every way that actually matters.

3.

You're retying them every time.

Different dock, different height. With a traditional fender you're committed the moment you hang it — and if the height's off, you're starting over.

CANNON attaches anywhere with a soft shackle that goes intuitively around any cleat or rail. No rigging, no fussing. And once it's on, DREADKNOT lets you slide to exactly the right height on the fly. Just slide it and you’re done. You’re locked in.

4.

They're marking up your hull.

It's on the side. That gray smear right where the fender sits — dull, flat, won't buff out. You try not to let it bother you, but it does.

It's the fender. Traditional PVC transfers onto your hull over time, and it gets worse as the fender ages. You hit it with compound. It gets a little better. Never fully goes away.

CANNON is non-marking foam. It makes contact with your hull the way a fender should — and leaves nothing behind.

5.

They’re an afterthought.

Every piece of gear on your boat was a choice. The rod holders, the anchor, the cooler — at some point you thought about each one and picked what you actually wanted. Then you got to fenders and grabbed the cheapest round ones on the peg because they all seemed fine.

They're not. CANNON is the round fender for the boater who's particular about everything else. Buy it once, use it for years, and never think about your fenders again.

I like gear that doesn’t need babysitting, and this is exactly that. Took a few seconds to set up and I haven’t touched it since. It just works the way you expect it to.

“SOLID. NO NONSENSE.”

“First fender that actually gets it right.”

“SET IT. DONE.”

First thing you notice is how solid it feels. No air, no soft spots, nothing to mess with. Just works every time you pull in.

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.
