Carl,
This is how great innovation occurs,......in the past it was on the beach after ( during) a race,....now we can develope stuff in each others living rooms,..world wide!
Tell us more about the horizontal spinnaker, ( Aussie 18) set up,....do you ( or anyone) have a link to a picture?
Again, the topic is hi speed and safe,......and the 2 parts needed ( amoungst others) are;
a) deployment and retriveal
b) sail design and size
....thanks for the info so far.......
