It seems like Chinese robots are able to weld aluminum boats at low costs.  Please compare western made
catamarans to Chinese ones in the 17 to 24 meter range.  I am interested in price, internal square footage,
if it is power, sail, solar.   The material used.   Try to give estimates for the number made each year.
Also growth rate for the company making the boat.   I am mostly interested in live aboard yachts,
but some interest in other types of catamarans in this size range.
