I am an avid sailboat racer including several weeklong offshore races, but I’ve never lived on a boat before so I’m looking for advice and things to consider. I live in Houston.

What is the minimum length for a sailboat capable of crossing oceans with at least two people?

Any recomendations for a specific kind of boat? Something that I could operate with one other person.

Ok, picture this:

A sailboat is on flat, calm water, with no wind. The sails are open. A fan is on the rear end of the sailboat blowing an unlimited amount of air into the sails.

Would the sailboat go forward, or reverse?

I am going to be learning how to sail here pretty soon so i am a bit curious what i would need be able to go wherever i want.
