Mariner 4 Features

Interior Space and Inflatable Seats

The Mariner 4’s interior is approximately two and a half feet wide, comfortably fitting four people. It includes three inflatable seats that snugly fit inside the boat, preventing them from sliding around. These seats keep you comfortable while you’re rowing around on your adventures. 

Hard Floor

The Mariner 4 is unique as it’s the only boat Intex makes with a hard floor. This 2-centimeter thick floor increases the boat’s durability and comfort, especially while fishing. The hard floor enables you to customize the interior with swivel chairs and allows you to stand up when casting. Typically, boats with this feature cost two to three times more, making the Mariner 4 a cost-effective choice.

Fishing Rod Holders

If you plan on doing some fishing while you’re out on the water, Intex offers two fishing rod holders that can be easily attached to your Intex Mariner 4 Inflatable boat. These holders will keep your fishing rods secure and easily accessible—a nice feature when fishing.


Constructed like a whitewater raft, the Mariner 4 has three layers: a polyester layer sandwiched between two extra-thick PVC layers. This construction offers strength, durability, puncture resistance, and resistance to sunlight, abrasion, and even gasoline.

Storage And Portability

When it comes to storage and transportation, the Intex Mariner 4 is a breeze. It inflates and deflates easily and can pack nicely into a compact size, making it easy to store in a closet or trunk. It also has a storage bag for easy storage and transport. However, this boat is pretty heavy when deflated, so it might need a strong person to carry it.


Thanks to its well-designed Boston valves, the Intex Mariner 4 inflatable boat can easily inflate and deflate. Its high-output air pump allows you to inflate and deflate the boat quickly. 

Safety Features

The boat has five separate inflatable compartments, four on the main body and one on the keel. This means that if one compartment loses air, the other four compartments will still provide safety, allowing you to make it to the shore. Additionally, the boat features a rock guard that runs all the way around it, protecting it from damage if you bump into rocks.

Inflatable Keel

The Mariner 4 is the only Intex boat with an inflatable keel, which offers better stability in the water. This makes steering easier, whether you’re using the outboard motor on the back or the included paddles. 

Accessories Included

Motor Mount Fitting

If you want to take your boating experience to the next level, consider adding a motor mount and trolling motor to your Intex Mariner 4 Inflatable boat. The Mariner 4 has a motor mount fitting, allowing you to install a motor mount kit on the boat easily. This boat can accommodate motors up to 3.5 horsepower

High Output Air Pump

The Mariner 4 comes with a manual high-output air Pump. This unique pump fills air into the boat when you pull out and push in, which means you can fill each chamber relatively fast. An electric pump will do the job quicker, though. So you might consider using one.

Oars And Oarlocks

With the Mariner 4, you have 54-inch paddles that are longer than most, making it easier for you to paddle long distances and reach your destination. The 360-degree oar lock system allows your paddles to rotate smoothly in any direction for efficient paddling.

Repair Patch Kit

The Mariner 4 include also a repair patch kit to help you fix a hole in the material, which really comes in handy when you need it most.
