We took all silver/plastic ware, plates, cups, coozies, rope, anchors, 3 batteries, electronics (stereo, GPS and radar display), life jackets, fenders, and pillows. We left the canvass hanging from the frames with lots of silicone packs placed in them, left cushions but propped them all up on their ends. Opened the doors, cracked the hatches about an inch, put ventilation strips in the shrinkwrap and put out 6 cups of baking soda through out.
We live in a bi-level and dont have a basement. If we did, the cushions and canvas would be home with us. As it is right now, they would just be stored outside, up in the garage rafters, and would see no difference in temp. from keeping on the boat.
