Tips for operating 100'+ motor yacht

Ha, no doubt.
On the West side of the Exuma Chain I always sail, nice quiet, protected from the Atlantic and pure pleasure.
Now I regret selling my sailboat. May have to look for another one.
To young to be a powerboater.

Not often. The lunacy is often too much. There are some very knowledgeable sailboat owners and operators, but on the forums the "live on $500 a month" and "sail the world without any training or experience" seem to be the loudest.

Sure, bunch of dreamers out there, but some do it: Sail into into the sunset at $500 per month. They are usually 26 years old on a 26' sailboat with a 19 year old girlfriend, life is good.
The other end is the newly retired couple with gray hair who needs a $500k factory new sailboat with a micro wave oven, washer and drier as well as air condition.
Guess who have more fun...?

I am somewhere in between: Sailing the Bahamas for 3-4 weeks between flying gigs with big airports, bad weather, jet lag, stress and bankruptcies.
The perfect escape, although $500 a month may be just that month in the Exumas after all the maintenance is done, the upgrades are done, the insurance are paid for and the booze/groceries charged to the Visa card.
So yes, $500 per month is doable, but not every month..

Aye Pascal, you are doing the best of both worlds, or neither, but you are not 26 anymore?
I went wild at 28, bought a 44' Bermuda Yawl, never sailed or owned a boat.
Worked my tail off to pay for and maitain a 30 year old wooden Rolls Royce in Cartibean warm waters.
Big mistake, but had a young wife who liked to make love under the stars.
Rice was $10 for a sack and rum was $2 per bottle.
Would not have traded for anything, and it came to
less than $500 per month, after the boat was paid for, but no insurance..

That's the ticket.

Towing a 26' center console would be a lot more functional!

I might have posed a similar question to that of the OP here, but the advice that came from you all seemed pretty much spot-on. I have to question the wisdom of the OP if, after his stint here, he seriously thinks he'll get 'better' answers to his MY questions in a sailboat forum? Seems to me that's a totally different world and, if he doesn't realize this, then.... :/
