Homemade Kayak Carrying Backpack System

This ‘how-to’ article was written to hopefully inspire you to make your own carry system. For those on a budget or for those not wanting to purchase a ready made system, this is the article for you.

First off, choose a suitable backpack that you are willing to cut up. In my case I chose a 35 liter bag that was still in great condition but I just wasn’t using it. When choosing your bag make sure the bag fits you. The distance between the top of the shoulder straps and the waist band is important. For me, the bag I chose was actually a bit short for the size of my back and because of the age of the bag, it offers little in terms of adjustability. If you make the wrong choice here you might regret it later on.

Have a look at your chosen bag and cut off the lid and then also cut off the entire bag part away from the back pad. The shoulder straps and waist band will probably be attached to the back pad itself. When cutting the bag away make certain you aren’t snipping off anything that will compromise the strength of the straps or the waist band as this will make life very difficult for you. I used a normal sewing machine for this job but an industrial machine will enable you to sew through far thicker material and you could really make a bag from scratch quite easily if you have a little imagination. Get somebody to show you how to use a sewing machine, it’s very easy actually!

So once you have your bag all cut up you’ll need a suitable sewing machine, some 25mm broad webbing, some clips, maybe this article and a brain. I used the thickest needles and thread I could get from a fabric shop nearby and no matter what I threw at it the needle never snapped.

There are three straps that go around the kayak. At the top the strap goes over the top edge of the cockpit rim and grips nicely there. The centre strap simply wraps around the boat and the bottom strap can either go through the extra handles (as found on most modern creek boats) or through the grab handle at the tail. Your choice will also depend on how long the boat is and how tall or short you may be. Once you made the bag with it’s straps you can fiddle around with it.

Take a short piece of webbing (about 200mm long) and loop it through the female end of a clip. I used three ‘strips’ of sewing and ran over the same stretch a total of three times. Feel free to add on as you feel necessary. You are then left with a tail of about 80mm long and this free end must be sewn directly onto the bag, at the back – the side which the boat will be on. You can make up three of these so that they can be attached all on one side of the bag at the top, at the bottom and somewhere in between. Please note how the top and bottom straps are sewn onto the bag at an angle. You can find this angle by placing the bag roughly on the boat and thread a strap around the boat in the correct position. Use a marker to outline the position of the strap on the bag and then sew it on. The angle is not critical but don’t just sew the straps all on perpendicular to the bag otherwise you will have unnecessary stress concentrations on the top and bottom straps where they are attached to the bag.

What you should now end up with is a bag with three ‘tags’ coming off on one side each with a female clip sewn on. Next up you need to sew on a piece of webbing to the opposite side of the bag as a mirror image but without any clips sewn on and the strap must be much longer. Again, one must put the bag onto the boat (on the underside of the hull) in a rough position and thread the strap around in the desired position and then add at least two feet extra and cut it to size. This extra length allows for more adjustability later on once you’ve got the boat on your back. If you cut the strap too short now you will be sorry later on. Lengths of around two meters are roughly what I ended up using. The shortest one would be the middle strap as it has the shortest distance to go. While the bottom and top straps are much longer. With the long loose straps sewn onto the back of the bag you just need to thread the male clip onto each of them and voila, your bag is ready to go!

Of course there are a few other things you can do. I took the sewing machine to the bag and reinforced the area where the shoulder straps attach to the top of the bag, as well as the bottom. Just use your common sense here and have a look how the straps are attached to your bag.

Then to add more comfort I bought another foam mattress to replace an old one and cut up the old one. I chose a width such that the foam would be a double thickness under the shoulder straps and a single thickness on top, away from yourbody. If you add too much padding it will make storing the bag in your boat more of a mission. Duct tape can be used to secure the foam to the shoulder straps and I did the exact same for the waist band. You will notice that I fastened the foam tightly around the shoulder straps but then made it tapered towards the end. This allows me to get my fingersin to still adjust the length of the shoulder straps. This will depend on the design and size of your bag.

I may still add somefoam onto the back pad itself but so far I’m fairly happy with what I’ve done. This is by no means a guide to build the ultimate carrying system so it’s up to you to find the shortfalls and improve on the design. Hopefully this has given you a little insight and motivation to make one for yourself. The entire process took less than four hours. Give it a try and you’ll surprise yourself how easy it is. Good luck.
