Author's Notes:
[1] Because the draft of this type of boat was so shallow, even when the seas were a little high, there was a great danger of turning over, so it was transported disassembled and re-assembled at its operating locale.

Thanks go to Matthew Jones for help in identifying COs and to Erich Muehlthaler of Germany for info in Rev 1.
