Stop fighting with knots and scuffing your hull. CANNON is built from premium non-marking foam — and with DREADKNOT technology, setting your height takes one slide.

Good enough is the enemy of great. It's about time someone built a better round fender.

Most traditional fenders are throw-away plastic junk that deflate and fail over time. They're a hassle to adjust, notorious for messing up your gelcoat, and height adjustment means tying and retying knots every single time.

CANNON handles all of it. Built from Mission's premium non-marking foam, it never deflates, never marks your hull, and holds its position. DREADKNOT technology means no more wrestling with your line — set your height in seconds and you're done. Works with cleats, rails, and Phender Pro right out of the box.

CANNON rolls naturally against the dock, stays exactly where you set it, and looks exactly like what it is — the good one.

Dimensions
8" diameter × 24" height

Fits best on boats with 30 inches+ of freeboard.
CANNON hangs as a pendant style boat fender from your cleat or rail, so it needs room to drop freely down the side of the hull. Boats with at least 30" of freeboard give the fender the clearance to hang at the right position and do its job. Running less than that? Check out SENTRY or DYMON.

CANNON is available in 2-packs and 4-packs. Each unit includes:

CANNON foam fender
Integrated DREADKNOT fender line with slide lock
Soft shackle attachment

The Good One.

The round fender. Without the round fender problems.

WATCH IT WORK

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.”

Roger M.

“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.

Scott T.

Set it in seconds.

DREADKNOT technology lets you dial in your fender height on the fly — no knots, no retying, no hassle.

Never deflates.

Closed-cell foam means no air, no valves, no failures. Ever.

No marks. No scuffs. No residue.

Mission's premium non-marking foam protects your gelcoat without leaving a trace.

Attaches anywhere.

The soft-shackle connection works with cleats, rails, and Phender Pro right out of the box.

Rolls with the dock.

The classic round profile scrubs naturally against any surface, staying exactly where you set it.

Built to last.

Mission's highest standard — every detail, not just the ones you notice first.

Dialed in.

Nothing about CANNON — how it works or how it looks — is an afterthought.

Phender Pro ready.

Swap to Phender Pro hardware in seconds and get the best of both systems — quick-link docking and DREADKNOT height adjustment working together.

Set it once. Get on with it.

Set your height, slide the lock, and forget it. More time on the water, less time dealing with your gear.

Way better than the old fenders
My old fenders didn’t hold up to the abuse they got from my houseboat. These seem like they are going to be a great improvement.

These are awesome!
Absolutely love my Cannon fenders! They've made docking so much simpler, and I will never go back to traditional fenders.
