Attwood 66398-3 5-Inch Stainless Herreshoff Cleat

A cleat is one of those parts you don't think about until you need one, and then it's the most important piece of hardware on the boat. The Attwood 66398-3 is a classic Herreshoff-style cleat, 5 inches long, cast from 316 stainless steel. It's the shape you've seen on decks and docks for generations, the open-horn design that lets you throw a couple of quick figure-eights around it and walk away knowing the line will hold.

This one uses a hollow base. That means the underside is open rather than filled, so the cleat sits a touch lighter and gives you a clean look once it's bolted down. The bright, polished finish stays looking sharp season after season, and because it's 316 stainless, it shrugs off salt spray, rain, and the general abuse that dock hardware takes. Corrosion resistance isn't a nice-to-have out on the water. It's the difference between a cleat you replace every few years and one that outlasts the boat.

At 5 inches, this is a small-to-mid cleat. Think dinghies, jon boats, small runabouts, pontoon corners, and dock edges where you're securing fender lines, spring lines, or a light painter. A good rule of thumb is roughly one inch of cleat for every 1/16 inch of line diameter, so a 5-inch cleat pairs naturally with line up to about 5/16 inch. If you're tying up a heavier boat or want a primary bow or stern cleat on something bigger, step up to a longer size in the same family. For most small craft and floating docks, though, 5 inches is the sweet spot.

Mounting is straightforward. The cleat has four pre-drilled holes and bolts down with four #10 fasteners, which aren't included, so grab stainless machine screws or lag bolts to match your deck or dock. On a boat deck we always recommend backing the cleat with a plate or large fender washers underneath. A cleat is a load point, and the last thing you want is the mounting pulling through a cored deck under a hard yank. On a wood dock, lag bolts into solid framing do the job. Snug it down, and you've got a tie-off you can lean on.

Where does it earn its keep? Bolt a pair to a floating dock so you always have somewhere to cleat off the dinghy. Add one to the bow of a small skiff for an anchor line or a tow. Mount a couple along a pontoon to hold fenders in place. It's equally at home as a spare or a replacement for a tired cleat that's gone chalky and pitted. Because the Herreshoff shape is so common, it drops right into the same role a worn-out cleat was doing.

There's a reason this design has stuck around. The open horns are easy to reach, easy to wrap, and easy to clear in a hurry when you're casting off single-handed. The rounded profile is friendly to lines and to bare feet, which matters more than you'd think on a small boat where everyone's stepping over the hardware. Attwood has been building marine gear for over a hundred years, and a simple stainless cleat like this is exactly the kind of no-drama part they do well. Buy it, bolt it, forget about it. That's the whole point of good hardware.

Keeping it looking new is easy. A rinse with fresh water after a salty day and an occasional wipe with a stainless polish is all it asks. No moving parts, nothing to lubricate, nothing to adjust. That's the beauty of a solid cast cleat. It just sits there and does its job, year after year, in weather that eats cheaper hardware alive.
