We provisioned at Riteway next to the Moorings/Sunsail base a couple weeks ago. Shelves better stocked than any grocery store here in Atlanta. The fresh produce selection they had would put our neighborhood Kroger and Publix to shame. So yes, water no problem. Though we actually wound up buying all our water, beer, wine, and liquor at Caribbean Cellars which was along the way on our walk from Sunsail to Riteway. Then we had our taxi stop there on our way back from Riteway and picked up all our beverages ready to go!
