I am a land based person, not a charter boat person, but considering the length of the flight even from the west coast, and the time change, I think you are pretty ambitious to think about doing a charter in a total of ten days. As someone else mentioned, prices in French Polynesia for everything are through the roof! We did a very reasonable big boat cruise (well, about 800 passengers, which is small for cruise ships these days!!) and we gave ourselves a day or two on each end to try to decompress and it was sorely needed. I think doing a charter, having to provision and everything else, I just think maybe that's too much to pull off, especially when you're not familiar with the area, considering how long it takes to get there, and the time change. If you want to still go there, I would recommend either doing a big ship cruise or a crewed charter or just a land based trip on a couple of islands. It is a spectacularly beautiful area, for sure.
