Reversable sailboat?

Good day, all
I'm over on the big island of Hawaii and I was out at Kohala Harbor today walking about. This interesting rig caught my eye. Could you guys help me identify it and supply any information you have to hand? I am speculating that it is a "non-tacking outrigger design" as I have never seen anything like it before. It has two roller furling jibs, one at each end of the vessel, a very small main sail and I believe two rudders, one at each end but hung off the side. Both the hull and the outrigger are double ended. If it works like I think it does, do you sail her with the outrigger to windward or to leward?
I will try to locate the owner to get a bit of history on it.

Welcome to the forum.

It is a proa. There is quite a large fan base in this forum. "Hary Proa" is probably the most recent thread.

 

24ft pacific proa, called Coconut, locally buildt, operated as a sailing school boat. Site: Construction Of The 24-Foot Proa Coconut https://oceanpeople.org/24-foot-sailing-fishing-proa/

The outrigger called an ama is to windward. You fly the Ama sailing.

 

Thanks for all of your replies. It's not often I find a new (for me) concept at my age. And it's always fascinating to see the way designers and engineers solve the problems of stability, drag, and strength.
Best regards,

We proa designers call proas that change direction like that "shunters". They are the dominant type of sailing outrigger throughout Micronesia, Kiribati and Fiji. Hawaiian sailing canoes tack in the normal way as they do in French Polynesia.
