Yeah I didn't think the wheels on most of the carts were trail worthy either. I have to take the kayak about 1/2 mile on a rocky scree abandoned jeep trail to the lake by my property. Bike wheels were on the menu but then when I do travel, I'd like to have a folding storable cart n that triggered my curiosity.
I've been tossing ideas up at work with the other carpenters n trades, everyone has contributed something to a design I'm in the process of prototyping. Once i get it on the kayak, I'll post some pics for more mods.
Paddleboy has some nice designs. I did some surfing on the web n found lots of styles of carts. I just need one I can copy off but I am looking for sturdy, light n packable.
Conneticut river, Hudson river, Long Island Sound... n many more are on the ta-do list.
Thanks
