The thought has crossed my mind!
Minor correction...
I have 1 complete AI, 1 almost complete AI, and 1 Adventure (aka Revo 16). Only a mast is lacking from the almost complete AI, and I've got a $200 used windsurfing mast that I'm trying to use, as opposed to $800+ for a "real" AI mast from Hobie (I'll start a separate thread for that). My plan is to sell one of the AIs (wifey insists :smt012), and then build the Adventure into a full AI, with everything built by me (or scrounged from cheapo parts) other than the hull (well, maybe the mirage drive will have to be Hobie too). We'll see how that goes...
JoeDubC:
Looks like ABS pipe, which might be as strong or stronger than PVC? but less flexible. Also the drilled hole removed tensile strength along the top, hence the crack originating there. With Sch40 or Sch 80 PVC larger diameters can be weaker if the wall thickness is not thicker. The schedule 40 refers to a fixed wall thickness, regardless of pipe diameter while Class ratings refer to water pressure. So Class 200 can be thicker walled than sch40 in the larger diameters.

Thanks for the info.
Sounds like PVC is the way to go and I should try again, maybe this time with regular PVC.
I tried to extend the rear roller with a block of wood but will see what else I can come up with to extend it further to prevent the PVC from bending too much. If I can get that rear roller another 1-2 feet back it will prevent a lot of tension when loading the kayak onto the trailer. That is when I have the least amount of control and at times the kayak really put a lot of pressure on the PVC pipes.

I also used the gray PVC like NWM for my TI trailer. It does bend, but won't crack like ABS.
