My kayak weighs 66 pounds and all of my gear including food, water, life jacket, and kayak seat weigh 45 pounds. When portaging, I put nearly all of my gear in a Duluth Pack usually leaving no more than about 15 pounds in the stern of my kayak. The gear that I left was only the gear that would be balanced over the the portage wheels. This apparently is too much weight for the portage system I was using. What I don't understand is that other people seem to have been portaging similar weights without their portage system failing.
Kayak
I'll build a light weight cedar strip kayak that will give me the option of portaging it on wheels or on my shoulders when the portage trail is rough. I did not have that option on this trip. Due to the length of the portages, my only option was to portage my kayak on wheels. I'm going to build the kayak with a cockpit shaped and balanced to be used as a portage yoke.
I believe kayaks are safer and faster on the water, but harder to portage. They are less vulnerable to the wind and waves than solo canoes. If I can get the cockpit shaped and balanced correctly, I might be able to design a kayak that is almost as easy to portage as a canoe.
Cart
I'm likely going to build a cart with the following features:
- Fits under the middle of my kayak so that it takes less effort to hold up one end.
- Has a bracket that fits over the kayak which will help keep the kayak and cart in alignment.
- Has very large diameter wheels that can go over rocks and roots.
- Is sturdier than the commercially available carts.
- Can be folded and strapped to the back of my kayak.
