Rudders:

If you want to leave the rudders on the boat you have to stablize them from falling down and blowing sideways in the wind. Take an 8 foot piece of 1.5 inch PVC. Near each end cut a notch as a saddle for each rudder. With each raised rudder sitting in its notch on the crossbar, run a line from each end of the bar over your mast and suspend the rudders/pole from that. I included a length of bungy to allow for road-bounce. This suspension cost about $2 and takes about 10 seconds to hook on. The rudders can't fall or swing off center.
