I have been using Yak's Rack-And-Roll.
Nice trailer - people even come up to me unsolicited to remark how cool it looks.
But I think the Hobie trailers are more functional for my use (especially the lower loading height) and I am going to sell the Yak and replace it with one of the Hobies.
I don't want the minimal single-backbone trailer because I want the option of mounting my rooftop box next to the AI if/when it seems like a good idea. ..... I also want more weight capacity.... my rig is an easy 250# as sailed.
Sometime ago, I asked if mounting a single AI off-center to accommodate the much lighter rooftop box would create a balance issue and the answer was "No".
I am assuming that the height will be sufficient for me to insert the scupper dolly while the hull is halfway-off of the trailer.
Once I get it working conventionally, I might even attempt an approximation of FastLane's integrated wheels - only for the AI instead of the TI: https://www.youtube.com/watch?v=c1xuRFzLeik
I am guessing that the "Double" (http://www.austinkayak.com/products/487 ... ouble.html
) is what I am looking for, but want to make sure.
