���Ninja is a nice boat concept that can be either a proa or tri. I love the design genius applied but not the final result. Watching her being sailed reasonably hard and she looks like she wants to sink the leeward ama all the time, lots and lots of aka spray. I very much like the Outrigger junior, similar dimensions, a bit heavier and more stable as well as being much better looking. I also think with a little bit of design change it could become a beautiful small trimaran. I would go the outrigger junior over the Ninja any day.
