potable water. Even warm water tastes good when you need it. Flash light,folding knife Potty paper,Spare fuel,couple of tools, bilge pump or bucket, something to fill in a hole in the hull, Like a nerf football and duct tape and plastic table cloth, for those just below the surface stumps or floating just beneath the surface containers that tend to find the hull just below the water line. Don't forget the registration and a float for the keys. A couple of fenders will work, the bigger the better.
Good luck.
Keep it up,
