I beg to differ about performance (not the manufacturer) boats being too weak and 'breaking too easy'. From a rental boat perspective, there are a lot more ropes, hardware, and sails to maintain on an I20 or Nacra6.0 whereas boats like the wave or Getaway don't have the high performance systems, are very simple, and cheaper to maintain. It's not really about breakage - more that there are fewer wear parts. We sailed an I20 offshore in the Tybee 500 and I promise you there's only one or two other catamarans I would feel safe on in that kind of mayhem - and none of them on that list are made from rotomolded plastic.
