Regards, It has been said that a wife and a steady job have been the ruin of more sailors than anything else. I would like you to consider some things before you cast off.

Jeff, if you don''t know what i am talking about you will never get to where you want to go.
You have to know this inside and out, forward and backwards and be able to do most of in your head.
My point is, that maybe a traditional high school is not right for you but in order to be a good sailor an education is essential. Check out some the "Sea school" programs, Navy and or Coast Guard. Please remember that the Buddhist monks don''t have solar panels and GPS, so if you want to go simple and cheap and keep your boat off the rocks. Please studying navigation as a start to your on water education.
