Onyx Type IV Throwable Foam Cushion, Blue, USCG

Every boat needs a fast way to help someone who ends up in the water, and that's exactly what this Onyx Type IV throwable cushion is built for. It's a U.S. Coast Guard approved throwable flotation device, the blue foam cushion you've seen tucked under the seat on almost every boat at the ramp. Simple, proven, and one of the easiest ways to make sure your boat passes a safety check.

Here's the deal with throwables. On most recreational boats 16 feet and longer, the Coast Guard wants a Type IV device on board and immediately accessible, in addition to a wearable life jacket for every person aboard. This cushion checks that box. Keep it where you can grab it fast, not buried in a locker under three fenders and a cooler. If someone goes over, you've got seconds, not minutes.

The design is about as no-nonsense as it gets. Two webbing grab straps run across the top. In a rescue you grab a strap, throw the cushion toward the person in the water, and they hold on until you can bring them back to the boat. Those same straps work as carry handles when you're just moving it around the dock or stowing it for the season. A person in the water can hug it to their chest to keep their head up while they wait.

It's made to take a beating. The outer shell is a durable nylon oxford fabric that shrugs off the scrapes and scuffs that come with living under a boat seat. Inside is soft, comfortable foam that gives it the buoyancy to do its job. And because that foam is genuinely comfortable, plenty of boaters use the cushion as an extra seat pad on a bench or cooler during the day, then it's right there if they ever need it. Dual duty, no wasted space.

The cushion measures 15 inches by 16 inches by 2.5 inches, so it's compact enough to sit flat under a bench seat or on a shelf without eating up storage. The blue color is easy to spot in a hurry, which matters when the adrenaline's up and you're reaching for it fast.

Because it's a Coast Guard approved Type IV device, it carries the approval marking a marine officer looks for during a safety inspection. That approval is what separates a real flotation cushion from a regular boat pillow. A comfy seat pad that isn't rated does nothing for you legally or in an emergency, so it's worth having the genuine article aboard.

This is the right pick for just about any boat owner who needs to meet the throwable requirement without overthinking it. Bass boats, pontoons, center consoles, small runabouts, all of them can carry one of these. One thing to be clear about, though. A throwable cushion is not a life jacket and it's not meant to be worn. It doesn't replace a properly fitted wearable PFD, especially for kids or weaker swimmers. Think of it as the extra layer you throw to someone, not the one they strap on before the boat leaves the dock.

Take care of it and it'll last you years. Rinse the salt off now and then, let it dry fully before you stow it so the foam doesn't hold moisture, and give it a look at the start of each season. You're checking that the fabric hasn't torn, the straps are still stitched tight, and the foam hasn't gotten waterlogged or hard. If it's soaked through and won't dry, or the shell is ripped, retire it. A throwable only helps if it actually floats when you need it to.

Boating safety gear is one of those things you hope you never actually use, but you don't want to be caught without it. This Onyx throwable is cheap insurance, it keeps you legal, and it does exactly what it promises. Grab one, keep it somewhere you can reach, and forget about it until the day it matters.
