Faithfully, I hadn't had any adventurous trips in my life. I was busy with my career. I thought to have a change and looked for an adventure, there I found out that. I am new and don't have any experience in cruising. But I liked that innovative idea.
You did not mention your location nor your goals
I am assuming your bride is on board with you and like you has little experience.
Charter a boat you like! Be gone for a week.
Buy a boat that can be handled by 2 people. Start small and if you want, you can move up to a larger boat. Diesel of course. 1 or 2 engines, your preference. Reasonable generator. Bow thruster and stern thruster. Good to have the knowledge you can maneuver the boat in tight spaces.
Get a tech out to your boat who knows your engines, take a tour, ask questions, make notes. Then, hire a captain to train you two. That may take 4 or 5 days. Translates to BIG BUCKS.
I suggest you look at an American Tug. I have a 34 one stateroom. You might look at a 42, 2 staterooms. Look for closet space, drawers etc. on any brand of boat you might consider.
Once your friends discover you have a boat, "Can we go? Call us when you are ready to leave. (shore power off the boat, water hose off the boat, most of the lines removed.)" That translates to maybe a 4-6 hour cruise. Then you and wife are left with a half tied up, disorganized, dirty boat, inside and outside and no shore power on board.
Teach the guests how to use the head. Show and instruct them on the life jackets.
"Stuff": get it, use it, put it back where you found it so you can get, find and use it again.
I have a rule, no beer or booze served underway. I might need assistance and sure don't need the assistance of a drunk.
That may sound negative but, you will learn over time then, you can write your own rules.
