During this time, I was doing all the sailing without additional help. After they were satisfied that the vessel really did sail and sail well and was well-balanced, I suggested that we return to port, whereupon they asked how it could be done. I said that we could just turn on the engine to get through the bridge. They asked how that could be done without a rudder. None of the others have used this rig.
All sizes are also available as round bottom metal construction.
