In my eyes, you should focus first on sailing studies. find a proper sailing school and start learning. you will meet there people like you with similar dreams, you will also meet experienced people from whom you would be able to take good advices for questions you have.
Sea can be one of life's best gifts, but when circumstances deteriorate it can be cruel and unforgiving. theres more to sailing than just a few sailing lessons.
You have some money in the bank, thats good , let it stay there for awhile. dont blow it all in one go. builed your sailing skills and knowledge of what it takes to keep a boat.
my bottom
line would be. give yourself some time to have agood tast of it, before you get into the buisness of buying a boat.
Good Luck on whatever you decide to do
