I've pondered the same question. People look at the size of the boat and say, "That's a lot of boat for one axle." I'd feel safer with another axle assembly, personally. Start thinking along those lines, and pretty soon you're thinking about surge brakes. In the archives, you'll find a variety of opinions on both topics. One axle assembly, no brakes, is cheaper and easier to maintain. There is no question, however, that two axles, with brakes, would be the safer way to go. What's your risk tolerance? How deep are your pockets? Nearly every photo I've seen shows people using the original style single axles. I suppose the main thing is to make sure that whatever rig you have is well maintained. My boat had been sitting for four years when I bought it. Tried to pull it home by just greasing the bearings. Next time, I'll change the bearings before driving the boat. Bearings failed. Then the hub broke. Scary. Wound up changing one hub and both sets of bearings on the side of the road. Also, there is the issue of the tires. The previous owner had regular auto tires on the trailer. Regular auto tires are rated to carry about 1,000 lbs apiece at about 35 psi. The C-22 rig, for safety's sake, may as well be considered as 4,000 lbs, or 2,000 lbs per tire. Tires rated at that weight have thicker sidewalls and are meant to be inflated to about 50-60 psi, I think (don't know yet, since I haven't actually bought any). Good luck!
