I just purchased my first new kayak a 12' sit on top fishing yak. So I took my first trip out to Pinto Lake for a little bass fishing I had no problems on the way there but on the way home I had a bad vibration at all speeds. I have TRACRAC Racks on my 06 sierra, I hear putting a twist in the straps will stop this, and I had put the straps straight on the way home making sure there was no twist. Is this my problem? (kayak rookie) I did have a great time the fishing was slow but the weather was great, should have bought a kayak a long time ago.
