Tahiti, St. Thomas and the French Riviera — I’ve yachted in all of these exotic locales, albeit from the comfort of my couch. And, millions of Americans are in the same boat.

In 2013, “Below Deck,” introduced the masses to the most glamorous mode of traveling: yachting. Since then, it’s become a Bravo mainstay with Season 9 of “Below Deck Mediterranean’’ premiering in June. But how real is the reality show? I spent five nights on a yacht in Croatia to find out.

A tip on tipping My suitcase wasn’t bursting with Benjamins. An agency at your final destination provides cash for the crew’s tip money. While you’re expected to tip $30,000 for a two-night cruise on “Below Deck,” in real life you only have to tip 10% to 15% of your charter fee.

That’s about $10,000 for a two-night cruise on a 180-foot charter yacht like Mustique (from $250,000 a week), which stars in the new season.
