1)No moving skeg. Instead of that I made a metal skeg, and with that I can turn either side if I need (manually) and it helps me to go in a straight line. I am able to achieve a maximum speed of 10Km/h, (not cruising speed).
2)To make it easier to transport I made a flat top not a curved one.
3) Also because of the flat top cover I made an open frame on the place we usually put the cockpit.
