It is crippling stuff to see how far Dugg has been really off with so many aspects of this BSO. As you correctly point out regarding his rigging, there have been two preeminent methods for setting up the sail controls, readily available from any good library or book store. He could have taught himself, well in advance, how to properly set up one or the other and then stick to it. Sadly, he appears to prefer learning things the very hardest way imaginable in this day and age. Trial and error.a la Hasler type rigs and as per the Colvin rigs. Both work. All Doug had to do was copy one.
Oh well it's sort of entertaining but I really can't bring myself to watch the smug vids.

The cherry on that bit of idiotic trial and error icing is indeed the near endless smugness he broadcasts to the world. Most observers just shake their heads in utter disbelief at the depth of this persons poverty of spirit and awareness.
