In an effort to keep this transport thread helpful, I wanted to post up my latest mod. I've hauled my Revo facing up and down at times, with measly results, using varous padding, etc. I have two other trad yaks, and lots of Yakima saddles and stuff. Most of this wasn't getting me where I wanted to be with the Revo, which is upside down, resting on firm non-marring padding.
I have two full sets of canoe brackets and decided to mod one set... I cut off the tops of the bracket since they would hit the rounded sides of the gunnel and wouldn't be a proper fit. Then glued on pads of mini-cell foam. After a weekend of running +/-300 miles, including 20-30 miles of sometimes rough gravel road, this is working very well. No shifting, squeaking, rattling, etc. No marring on the boat gunnels. Winds today were very strong, and no issues on highway at 60-70mph.
At 52

I can still powerlift the boat by the mid handles, kinda rest it on my shoulder on edge, and ease it down onto the end of the racks while standing on side of vehicle. Once half the weight is on racks and stabilized, easy to slip it sideways into proper position. Just a slight lift to clear the brackets, and it locks in. It can't go forward, back, or sideways. I've handled lots of kayaks, canoes, pirogues, and for the Revo, this is the easiest fastest method by far for me, but certainly not for everyone.
