Sailing around the world on a Sunfish - non stop

So, a friend's cousin's roommate has this small Sunfish boat behind the barn on his family's farm in Oklahoma. He is willing to give it to me for free! I will have to have it transported home to me in New York.

He said it may need a little work and some parts may be missing. He mentioned it also needs a new sail, mast, rudder, tiller, boom, centerboard, and ropes. The hull is in very good shape... just a few holes in the bottom that need patching.

My plan is to clean it up and to circumnavigate the globe - non-stop. Also, I will need to install a refrigerator to keep beer cool during the journey. What size battery will I need?

Any advice would be greatly appreciated.
