Racoones can be BIG problem. They will try to get to your food and WATER. I hosted water and food up on a mast on my trips.
On a solo boat I found that oars works much better than single paddle.
Typically, you can survive on two liters of water a day, unless it's very hot. Gallon a day was more than enougth for me.
