Built in Taiwan at the Ta Yang yard, the longtime builder of Tayana Yachts, the new Isara line of "semicustom luxury catamarans" is a fresh addition to the bustling multihull scene. The 50 is spacious and extremely stylish; owners play a major role in determining layouts and accoutrements. A 45 is coming soon. The Isara 50 is part of Cruising World's 2013 New Boat Showcase.
