Welcome to the forum! Great advice by all re: mono versus cat and, to that I would add the following: not only should you get some experience on both before making such a large purchase
, you should also get some sailing experience before deciding if this is a life you wish to pursue. Yes, there are courses available, but starting with a smaller boat of your own would have many advantages:
1. Your initial investment is kept to a minimum and, if you purchase
a popular model that is used, you will likely lose very little to depreciation in the short term.
2. You will find a smaller boat easier to sail, anchor
than a larger one.
3. If the investment is less and the boat is used, you will be less worried about potential damage if you hit a dock/run aground (and yes, I know you have power boat
experience, but docking/reversing a sailboat with a keel
can a much more difficult proposition).
4. The experience will give you a better idea of what you will ultimately want in a liveaboard
Anyway, good luck in your adventure!
