Re: Best place to provision for Panama-Tahiti
A couple of suggestions for you. We had good provisioning in Panama City on the Pacific side. There is a store, like Costco in the US, the is excellent. I forget the name but describe and everyone will know what it is. You have to buy a membership. We shared a membership with a couple on another boat to reduce the cost. You can get there by bus but will need to get a cab back (~$10). Prices are great - beer was about $9/24 and Chilean wine $2/litre. We completely loaded a cab with about $500 worth of shopping - could not have taken anything else.
There is an incredible hypermarche in Papeete that is within walking distance of the marina. May well be the best supermarket I have ever seen (it is huge, French, in the middle of the ocean, and on a large tropical island). Not cheap though.
Finished the circumnavigation in early February in Grenada. Have to work on a book project for the next several months so the boat will be waiting for next year.
