I know nothign about sailign, and never was into it, but the past days I occasionally watched TV coverage of the races between these two catamarans, and watched with growing fascination the different race track patterns both boats were circling into the water in search for the better wind. Also I like the boats.
I also know nothign about these boats, do not even know the name of their class, assuming they are not just "catamarans". And I am wondering. That the crew all the time change the side, probably is due to weight, but the sailors who are constantly turning those cranks like crazy - what exactly are they doing there? Do they drive a hidden propeller?
I have no clue what they are doing, since they are turnign the cranks all the time, always.
Whats it all about? Are they bored or try to keep warm?
