Probably wretched excess, but here is a link to a bunch of pix that might be useful to somebody else setting out on this little venture:
https://picasaweb.google.com/1081497986 ... ackAndRollIt's obviously not rocket science.... but I did spend a couple of days fiddling around getting everything "Just So"....
Bill of Materials:
- Three pressure-treated 2x4's,
. - Two 4" galvanized hex bolts
. - Two 5.5" galvanized hex bolts,
. - Four galvanized right-angle brackets
. - One set of pre-September 2015 Hobie cradles (the ones with the tapered fore cradle and not just two iterations of the rear cradle)
. - One 66"/200# capacity Yakima Rack-And-Roll trailer.
The 2x4s just lay on top of the Yak's crossmembers, having been slid under the Yak's roof rack bars.
Fore-aft movement is constrained by a section of 2x4 at each end held in place by galvanized right-angle brackets.
If/when I want to revert the trailer, 4 bolts let me remove the roof rack bars and lift off the whole cradle/2x4 assembly.
If lateral movement becomes an issue, I will deal with it then, but I am not expecting it to be a big deal....and it's not that hard to push the unladen assembly left or right.
If racking of the cradle/2x4 assembly becomes and issue, I will screw a small sheet of 1/4" ply to the 2x4's...... I did this on my breadboard implementation, but thought I would get away without it on the final implementation.
My primary concern is rub wear by the wood against the trailer's alu....... Hopefully this will be mitigated by the rubber that Yak puts in the channels on the top of the cross members........ Time will tell....
Don't be distracted by the white PVC covering the Yak roof rack bars: that's just to facilitate carrying the hull upside down without the cradles...... has no function at all with the cradle implementation.
FWIW, I am not totally in love with the Yak trailer.
It was attractive to me for four reasons:
- Basic elegance/cool-looking-ness
- Turnpike-speed safety
- Ease of moving around by hand on my lawn.
- Compact storage
It delivers on all of the above, but, in retrospect, I think I might have been well served by Hobie's Trailex trailer for $500-$700 less (depending on model) - especially with it's lower loading height and dunk-tolerance.
OTOH, with the Rack-And-Roll, I can see the boat in my rear view mirror and it seems likely that it would not be visible if it were on the much-lower Trailex trailer.
OTOOH, to get turnpike-speed reliability, I think I would have had to replace the Trailex's 8" wheels with 12" wheels and that might have bought it up to where I could see it in the rearview mirror.
