I have been using an inflated kayak (Sea Eagle SE-370) for 5 summers in a row, not a single quality issue. It's well built, and very tough.
Originally, I thought kayak cart is just invented for no good reason: who can't carry a kayak by hand!
I was wrong. Whenever you want a quick in/out of the launching ramp, the cart comes in handy. It's like a second person helping you to carry a lengthy timber log especially when the it's wet and you are tired.
The vendor supplied cart (called EZ-cart) is a little bit expensive (130$) and it's non standard: It's designed to carry Sea Eagle inflated Kayak only. I want a cart/dolly to handle both inflated and regular kayaks, and of course, cheaper.
Eventually I bought a general kayak cart (Seattle Sports TurboMite) from Amazon which costs around 75$. It's designed to carry regular hard shelled kayak. If I put my SE-370 on it, it just doesn't work: the inflated soft belly will always sink into the cart bar. The kayak and the cart just stick together and won't move.
There got to be a cheap and quick fix. The key words here are "cheap & quick", no drilling, no gluing whatsoever. It turns out that my DIV works well.
Here are the steps:
(1) This is the cart/dolly I bought from Amazon (Seattle Sports TurboMite)
(2) A 1.5"/40 mm PVC tube (using handsaw to cut it to be a little wider than the cart bar); One long buckled strap; Two short buckled straps. All these parts together cost around 10$ and you can get them easily from any local home hardware store (e.g. Homedepot).
(3) use the 2 short straps to tightly tie the PVC tube on the cart bar (the bar which will heavily touch the boat bottom) . Cross the long strap through the tube.
(4) Use the long strap to tightly tie the cart and boat. Do this at one end of the boat and you pull the other end of the boat when in action.
A closer look:
(5) lift and start pulling. If the weight causing the boat belly touch the ground, just lift it higher to avoid the touching.
A closer look (Click to view larger version):
(6) Result: It successfully passed the 150 meters bumpy slope (both downhill and uphill walking).
- This setup can only be pulled, can't be pushed. So if you want to "push" it, stop and do the U-turn instead.
- This setup is not a magic carpet. It can survive gradual slope no problem but can't climb a steep bumper like below (Just climbing part failed; Going down from it is just fine)
Hope this helps. Enjoy kayaking...
