We provisioned for 2 people aboard a 25' Watkins for 6 months. Mostly dehydrated food, some canned meats and fish, many items off the shelf like mustard, mayo, catchup etc. total of 22 cu. ft for all consumable supplies. We purchased fresh along the way but did not have to if we couldn't find what we wanted. Main source for food was (internet-grocer.com) We made up a Word doc and tracked what we loaded vs what we used. I'll send it if you request by email to
debandlou@verizon.net . Our Avitar picture shows our 25' Wu-Hsin in West end Bahamas about 30 days into the trip and about 5 inches lower than design water line.
