Congrats and welcome! I bought a big boat as a newb, too, but knew the basics. Sailing/racing were bigger goals than just having a place to live. What worked for me is to get comfortable
singlehanding whether that's sailing or maneuvering under
motor to get over to the
fuel dock. That said, without much experience, you could get yourself into trouble quickly, so latch onto
dock mates and other sailors for advise, and read everything you can get your hands on to learn as much as you can. Then, go put it into practice (after you've confirmed that the
weather is going to be mild on your outing). Thunderstorms roll in quickly in Florida! Have fun
As to tricks on
living aboard, clear out lockers occasionally so you can find stuff more easily and keep tools and boat
parts in smaller, individually-marked containers to find them when you need them.
