Does yakima sell something like the Thule Hullavator? If not, will the Thule work on a set of yakima cross bars?

 Mike- Have you had any issues with it sliding or rolling(side to side) on the Yakima round bars or is it pretty tight once installed?

I might register and go to Albion just for the chance of winning the one in the prize package. THis thing looks awesome.

The bracket that locks the Hullavator onto the square Thule bar is actually slightly curved. It should work fine with the round Yakima bar with sufficient tightening.

Yes, it slides a bit with the round bars.
Make sure the arms are squared up before you lift the kayak onto the top of the vehicle.
As easy as they might slide when putting the kayak into the arms, they square up just as easy.
Get the kayak loaded onto the arms, square up the arms, strap the kayak to the arms, lift.
No problem.

It works fine on my Yakima bars.   There is a lot of wind noise though.  I can not attach the fairing and use the Hullivators at the same time.

A LOT.

I have the square Thule  bars on my hullavators. They are on my camper so the noise is minimal unless a rod holder starts whistling or a strap really starts vibrating.

I just picked up a set of Hullavators from CL for $300! I was digging and digging, and found a set that was misspelled so they have been available for 20 days with no inquiries!
