The plan when I start to sail, is to not have a plan for a specific destination. I have this overwhelming fantasy of being completely alone ( I know it sounds crazy) And the thought of seeing nothing but sea in all directions, seems utterly relaxing to me.. I was aboard a cruise ship once with thousands of other people, and I was able to see nothing but water in all directions, and ever since then, I have wanted to chase that feeling I got.
Plus, star gazing is my favorite all time activity, so in the middle of the sea with no light pollution, the gazing would be amazing.
