Provisioning for 3-4 people for more than a month is quite an "art" and one of the biggest challenges of course is keeping fresh fruit and vegetables. We found that hanging a fruit hammock high in the cockpit was a good storage location, well venilated and relatively cool....although the temperatures of course gradually warmed up more and more as we neared the tropics.
Here is the final photo of our fruit hammock with the last of our lemons. We had affectionately named our fruit hammock "Dolly Parton" when it was chocked full at the start of our trip. Now it was named "Twiggy" -- you will only understand that reference if you were born before 1965!
