Re: Possibly buy a boat..
As long as you are not spending your life's savings on this boat, or if you are you at least know that when you get it you will be working to support your sailing habit from now on, then I say go for it, conditionally, but go for it.
The conditions that I would apply to the purchase are the survey, get survey done, be there with the surveyor and ask questions, you are paying him, so use that to your advantage. If the surveyor tells you all the stuff that is wrong with it and gives you a ballpark idea of what the repairs will cost and you are good with that, then you are going in with your eyes open. If you see that the boat is in decent condition for its age, and you jump in and buy it, knowing you sold your weekends and a lot of other "spare" time in trade for a future good time of sailing, then you are ready to jump in and own a sailboat. The Tartan is a very pretty boat, and from all reports a good one to own and sail.
It is good to learn from your mistakes, but much better to learn from the mistakes of others...
