Wow ,-beautifull design .

On larger cat designs the proportion of sail area to hull L and ratio of mast height is so much less comparitively that this configuration works well .

Researched into duel rigs by conducting a patent search ,-years ago ..
There are duel rigs on the old square rigger sailing ships in the 1800s shown on patents of the time with particular" les innovations "
There was an excellent book on -Curios Yachting Inventions ,-
most comical but you realize the intent and see progression from the concepts and how they influence and evolve .
It would make a great similar book now based on multihull design innovation ,-but add the connections in design to present day design reality .
There is really not much new conceptually ,-just a great refinement process of engineering materials and the attempt to refine the concept into working reality . It would be fasinating to document these early ideas and present day design corelations .

Sailing ,--its so much fun in so many different aspects of the sport ,-inc.design innovation .
It is very difficult to understand the concept of timed handicaping our cat racing here in N A .
iT IS COMPLETELY CONTRARY to {les innovations } and the progression and development of sailing craft design which multihulls are on the leading edge of .
