Reading your list of requirements reminded me of my problems finding a suitable design. I choose to take an established designer Schionning and an interior designer that had experience in boats to craft a 14.5m performance cat. I am 76 years old and have recently sailed it from Newcastle Australia around Tasmania and return, single handed. All winches are powered with a powered hand tool. The boat is called Flight Mode and can be viewed at Multihull Solutions, The Boat Works, Coomera, Queensland, Australia. It is for sale now and is in your price range.
