Thought there was topic on this general question recently but can't find it now so maybe not.
To get more focused answers, suggest best to advise;
1 Assume you will be sailing at least 2 up initially till you gain suitable skills and experience - is this correct?
2 Did you want a fixed keeler or trailer sailer able to tow home and up the coast to other areas?
3 Budget and age of yacht you have in mind? Are you expecting to do some maintenance and repairs etc on your initial purchase?
4 Assuming you have done some preliminary searching is there a yacht which appeals as a likely contender - eg a Tophat 25 or Spacesailer 24 or other?
Doing an introductory sailing course is recommended but not mandatory depending on your prior experience with boats and yachts, or off the beach craft. eg;
southerncrossyachting.com.au/product/introduction-to-sailing/Insurance for an inexperienced owner and older yacht can be an issue - search the many threads on insurance on the forum. You need at least 3rd party.
Suggest also search for prior threads on standing rigging life - 10 years being the normal renewal needed by insurance companies - but as per the threads this does not mean that standing rigging is going to break after 10 years - operational use, corrosion and maintenance being a factor obviously.
