best jon boat seat clamps

The jon boat seat clamp is perhaps the simplest, most intuitive seat mount solution on the jon boat market to date. You can buy these babies pretty much anywhere these days, and they install like magic. So it really comes as no surprise how they’ve become so immensely widespread for jon boat owners looking for a way to make that bench a little more comfortable.

But while it can be easy to find a seat clamp, the sheer number of options also makes it pretty tough to zero in on a choice that’s right for you. So if you were on the market in the hopes of finding the best jon boat seat clamps, this definitive guide should help you make the right pick.

How Do Jon Boat Seat Clamp with Swivels Work?

The genius behind the jon boat seat clamp is that it quite literally clamps onto your bench. They’re great for boat owners who might not be too handy, or those who don’t want to spend time with a tool box and drill. The ingenious design features a type of steel framework that clamps against your bench to keep the mounting hardware in place.

For the swivel seat clamp, the mount is replaced by an upgraded swivel hardware that allows your seat to turn around during use. This can be particularly helpful if you keep your gear and supplies in different areas of your boat, but don’t have the patience to keep standing up or reaching out just to get to them.

Things to Consider When Buying a Jon Boat Seat Clamp

You’d be surprised how manufacturers have switched up what was once a simplistic design. These days, there is quite a lot of variety in the jon boat seat clamp market, so it can be pretty easy to fall into a purchase that might trigger a deep sense of buyer’s remorse later on.

If you’re not the kind to have the patience for a tedious returns process, you might want to consider these factors before you make a purchase:


This one’s probably one of the most important considerations you could make when buying a clamp for your jon boat. These things are typically designed to sustain significant weight, but they still have their limits. While most manufacturers don’t really mention any weight ratings, you could get an average number by contacting them or by reading the manual.

Another thing about durability is construction. Most jon boat seat clamps are made from aluminum or stainless steel. This helps improve resilience versus mechanical damage as well as potential corrosion from water exposure.


You’d think that the mounting feature is all you really need. But the modern seat clamps of today can come with a bunch of added functions that make the more convenient, comfortable, and practical, especially if you’re in the market for a versatile piece.

Some choices don’t only swivel, but also slide to let you move closer to either the bow or stern of your boat. Others come with rubber coated mounting legs so as not to leave a mark on your bench. It’s also pretty common to find seat clamps that adjust so as to fit boat benches of varying sizes.


The whole installation process is probably the last thing you’d have to worry about when it comes to seat clamps for jon boats. These things just snap into place, and come with adjustable legs that you can move around to fit your bench as snugly as possible.

Keep in mind though that there are some clamps that have received poor reviews for stability. Some boat owners complain that their clamps come undone with the slightest shift in weight. That said, these clamps might require extra installation steps, not limited to bolting them in place to prevent them from moving around so much.


Of course, everything you buy for your boat should be something that’s built to last. Unfortunately, if you’re on the market for jon boat seat clamps, you’ll find that a lot of them don’t really care about quality. Lots of picks that are made overseas might entice you with their ultra low prices, but ultimately fail when it comes to providing reliable, safe performance.

On the upside, you can always check the warranty to see just how reliable a seat clamp can be. Boating supply manufacturers who are confident in their products will be more likely to slap on a lengthy warranty. The longer the coverage, the more you can rely that your boat seat clamp will be up to code.
