This past winter, we spent 6 months on our R-25 traveling the Intracoastal Waterway from Maryland to Florida and back. We echo the Grays philosophy on the casual approach to clothing and agree with their comments on the amount of clothing, shoes, layering, etc. We found that we could wear clothes longer on the boat than we normally do at home. As you pick out clothes to take, think versatility. We carried our calapsable mesh dirty clothes container under the v-berth insert and it was ready to take clothes to the a marina laundramat about once a week.
We built a shelf across the V-berth which held all of our everyday clothes for the two of us for the trip. We carried a few "good clothes" in the cave in a long flat plastic storage box that we rarely used. We carried a small dufflel in the cave to pack for overnights away from the boat.
As for food, we packed some food for the short term in the galley lockers. We didn't take all that much in the way of cookware and dishes. The cookware we took "nested" to conserve space and make more room available for food items. We also bought two under-table drawers from Campers World website and mounted them under the dinette for storing eating and cooking utensils. We made extra velcro closures for them so they wouldn't pop open when underway. Tupperware containers and large ziplock bags conserve space when storing dry food such as pasta, cereals, etc. We remove these items from their original containers, which are usually only partially filled.
The lockers under the v-berth held canned goods, pasta, and other non-perishables to resupply the galley lockers every few days. We also had one 18" calapsable canvas storage container in the cave for large cereal boxes and other larger bulky food items like cereal that didn't fit easily in the galley lockers.
You'll do fine, and on the upcoming trip you'll learn what works best for you and how to do it even better the next time!
Enjoy!
