The next thing to consider is your basic starting point: should you get a stern mount or centre mount raft frame?

Stern mounts are great if you always have other paddlers in the raft to provide power, you have a longer raft that you need help maneuvering, and you’re in moving water where you need to follow a line. The extra power from a stern mount frame, when you have paddlers in the front of the raft, provides that boost you need to get through a hole or over a wave.

Centre mounts are ideal if you don’t have other paddlers, and especially if you’re loading your raft down with gear on longer multi-day trips. Centre mounts also provide more stable control of the raft if you don’t have paddlers.

The next step is sizing up a frame for your raft, and figuring out how you want to customize it.

Using measurements between the sides of the raft, and the length from bow to stern, you can figure out the dimensions for the base of your raft frame. Once you have that established, you can start messing around with the modular frame parts to figure out your exact configuration.

You can buy pre-built NRS frames, or build your own from the ground up. Having some idea of the kind of trips you’ll do and the gear you’ll carry will give you a starting point for setting everything up with the exact raft frame components you’ll need.

This is a great step to do in store, so you can see exactly how everything works and fits together. You can even bring your own gear to help make sure you get things just the way you want them!

Attaching Your Frame to Your Raft

After you have your frame all setup, the next step is actually attaching it to your raft.

Although this sounds like an intense task, it is pretty straight forward.

You simply use straps to attach your frame to the various D-ring connect points around your raft. NRS straps are especially useful for this task as they’re designed to perform in wet, sunny environments.

You never know what the river may throw at you, which is why it’s important to properly secure your frame to provide a stable platform.

Now that your raft and frame are all setup, the last piece you need are your raft oars.

Raft oar length can vary quite a bit depending on the size of your raft, how your raft frame is setup, whether you’re on a seat or just sitting on a dry box / cooler, your height, and your personal paddling style.

That’s a lot to consider!

A good starting point is the rule of thirds: one third of the oar should be between the oar lock and your hand, the other two thirds should be the length of your oar and blade from the oar lock outwards.

You also want to make sure you have about a fist-sized gap between both oars when you bring them across your chest. This makes sure they aren’t hitting each other, but are still close enough that you can paddle comfortably.

Sizing Up a Raft Perimeter Line

This is completely optional, but something to keep in mind if you’re tackling tougher whitewater and plan on having other people in the raft. A raft perimeter line gives you something to hold on to for balance on more adventurous rivers, and gives you something to grab onto if you fall out of the raft and need help climbing back in.
