6:50 PM, the dock at a Palm Beach marina. A party charter returns from six hours of what the booking website called "island vibes" — and down the gangway comes a groom-to-be we'll call Tanner, 29, wearing a captain's hat he did not board with, sunburned in the shape of his life vest, walking like the dock is personally moving. His best man steadies him. Tanner, with great confidence and no accuracy: "I'm FINE. I had like six." He had like six on a boat, in the sun, since 11 AM — which, by the arithmetic this article exists to explain, is not like six anywhere else.
The multiplication problem
A booze cruise runs three multipliers no barstool ever applies: the double export — sun and sweat drain fluid all day while alcohol's vasopressin suppression exports more; two drainage businesses, one body, compounding hourly (and alcohol impairs heat regulation and sun judgment on top, which is why the party-charter burn always outpaces the sober boat day's); the marathon arc — 11 AM to 5 PM is six hours of pacing no bar night attempts, the same day-drinking math that governs sandbar Saturdays with the throttle further open; and the masking — constant motion demands micro-balancing that hides accumulating impairment, so everyone's internal count reads lighter than reality. Tanner's "like six" was billed as roughly ten. The captain's hat came free.
On land, six drinks is six drinks. Afloat, the sun co-signs every one of them — and the bill lands at the dock.
The dock-walk phenomenon
Then the landing, the day's most treacherous stretch, and it's two mechanisms wearing one wobble: sea legs — the balance system spent six hours recalibrating to a moving floor and now over-corrects on a still one, amplifying every impairment; and absorption catch-up — the final hour's drinks are still boarding the bloodstream as you disembark, meaning peak impairment often arrives in the parking lot. The non-negotiable: the ride home is arranged before the boat leaves the dock, every time, no exceptions — the one line in this cheerful article written in permanent marker.
The double settlement
Tomorrow's invoice has two accounts: a genuine hangover and a sun-day deficit, and the settlement must pay both — aggressive fluids with electrolytes (plain water under-serves the two-currency bill), real food, aloe and shade for the vest-shaped souvenir, and for the big-charter tier — bachelor parties, birthday flotillas, the bachelorette fleet — the county's established morning-after infrastructure: the full counter-formula, pre-booked as a group session at the rental house, because charter crews sink or swim together and the smart ones book the recovery when they book the boat.

Tanner, wedding weekend
The best man — promoted to logistics officer after the dock walk — pre-booked the group session for the morning after the charter. Eight groomsmen, one living room, one nurse, staggered bags; by 1 PM the party was pool-side instead of couch-bound, and the groom was upright for his own rehearsal dinner. Tanner's toast that night, captain's hat retired: "To the boat, the sun, and the man who understood that 'like six' on a boat needs a medical plan. Best best man in the county."
