Our list of odd things to take includes:
Citrus zester
Microfiber sheets (they take up little space/weight in the bag and are much more comfy to sleep on than damp cotton sheets)
Cornstarch baby powder
One of the foil & foam dollar store windshield sun shades (cut to fit the ports and secure in place with painters tape to help keep the interior of the boat cool)
Small,inexpensive floating flashlight
Coffee filter packs
1 large tervis tumbler per person
