G'day Jeremy... welcome aboard.
A little bit of advice from someone who bought a yacht on eBay, sight unseen...
Yachts are built to be sailed in, not to sit in ports
A lot of would-be sailors rot
in port along with their boats that they are forever upgrading, fixing, etc etc...
Find your boat, and as long as it has adequate safety equipment
... just go sail the f***a, that will tell you what needs to be done to make it good for a longer voyage.
