Not to be a wet blanket, but...
I was where you are now about 40 years ago. Here's my prognostication:
You just bought a used boat that you haven't used yourself and don't know the state of things like batteries, steering system, thru hull valves, radio age or condition, electrical system, including type and number of fuses needed as well as spare electrical panel and master switches.
Have you had the sails inspected/restitched?
Have you changed the anti freeze, the oil in engine and transmission?
Do you have spare belts and replacement fuel and oil filters?
Do you have the right tools to repair/service your boat's systems?
I didn't either but I went anyway. I learned how to fix the stuff that broke or replaced it (Some at great cost in the Bahamas). I lost many days in a yard getting things fixed that required a haul-out, and could have saved big bucks by doing them at my home marina before I left.
But I didn't know all that I know now, so I just enjoyed the trip.
What I did know was: How to use an EPIRB, DR and electronic navigation, proper anchoring techniques, listening to weather broadcasts and evaluating the conditions each morning and afternoon, and how to reef main and jib. And, how to pick a weather window to cross the Gulf Stream safely. That was so no one died.
The rest is just money over the transom and good sea stories.
Let me know how far you get!
Good Luck and Safe Cruising.
