We spent about 5-6 weeks in the Bahamas each summer for many years (teachers). We do not have a water maker, and did not catch rainwater.
With just my wife and myself aboard, our three tanks lasted us almost 3 weeks. We took showers every day and washed dishes using the 12V freshwater pump. Of course we did all this carefully and tried not to waste water. We always anchored and rarely visited marinas. We found that R/O water is readily available in the Bahamas on the fuel dock at most marinas, and at a reasonable price. So we did not dinghy jerry cans back and forth, we just pulled in to a marina fuel dock and filled up every 2-3 weeks.
This worked for us, at least in the Bahamas.
