It's good to have a floatation device, it's good for transportation.
It's also good to have plenty of food and water!
The woods can be dark and spooky so a flashlight will come in handy.
a canoe was helpful multiple times in Zane and the hurricane. it helped to get places without to much trouble. an example of a time they used a canoe was when they were making the get away from Dylan tumey.
unfortunately Zane Tru and Malivina didn't have much food, but Trus friend Dela had already evacuated New orleans, so they went in Delas apartment and she had some canned goods in her pantry.
There was not a flashlight included in the book but it would have been helpful to have one when they went in the shed to spend the night.
