We use Thule straps to secure the yaks to the racks, and bow and stern tie down lines for extra security. It does take a little time, but worth it to know the car and kayaks will safely get to the launch point.
We also have a set of Yakima cradles that we bought before the Thule set up. Good, but not as solid as Thule.
Bottom line: a little pricey, but worth it.
Durable, reliable and predictable. Have been in surf and the yak behaved very well. Still look great, not much color fade (and our kayaks are outside much of the time). We have looked at other kayaks, and may buy a couple of smaller kayaks for ease of transport and to use with friends and family, but (other than MUCH more expensive kayaks) have not seen a kayak for the price that is as well made and versatile as this one. Never regretted this purchase.
Rarely miss having a rudder and have not had any problem with the footbraces popping out.
9 out of 10 because the seat, while comfortable, could be better (but we have paddled 3 - 4 hours straight and not had a problem).
