Thanks! I put together the racks with some mounts from www.rammounts.com. I used a double U bolt with a 1.5" ball, connected directly to the existing rails on the top of the cabin. I used their long length double socket arm on each of the balls and then got Yakima cross bars to complete the rack. They are made out of marine grade aluminum. I opted for the long length arms so that the boards would be above my radar and not obstructing it. Works great, have had longboards, short boards, paddle boards, and kayaks up there without a problem. Got some long straps from dakine and they don't move. let me know if you have any questions.
