Also what we have found in solo sailing a Wave is to get a handle for the wheels. That way you can stay in front of the boat and with the handle slide the wheels under. No need to go from side to side tying them on. '
The tube that goes on the axle comes with bearings so the cradles always go upside down, which is a hassle. So, what we all did was set the cradles right side up and drill all the way through and put in a bolt. That way the cradles are always right side up.
Here is the link for the handle:
