The conception of the Pandora 8.50 has been articulated around the idea of drawing a balanced boat. We sailed a lot on similar catamarans to analyze their strong and weak points. We listened the potential users to bring concrete answers to their wishes. We removed the extreme options, nice on papers, but difficult tu use for most of sailers. We used our experience in various design office, especially in Australia where this kind of trailerable multihulls are more common and many choices are obvious.
