A first-time charterer sees a published weekly rate and reasonably reads it as the price. It is better understood as the largest line on an invoice that will carry four or five. None of the others are hidden. They are governed by standard terms that repay reading before signature.
The Base Rate and What It Buys
The base rate charters the vessel and her crew: the yacht, crew wages, the vessel’s own insurance, and the equipment aboard. On MYBA terms, the contract form used across the Mediterranean and much of the global fleet, nearly everything the guests consume sits outside that number.
The APA Funds the Week
The advance provisioning allowance, commonly 25 to 35 percent of the base rate and most often near 30, is paid before boarding and funds the consumables: fuel, food, wine, dockage along the route, and incidentals. The captain keeps the accounts and the guests may see them at any time; an unspent balance is returned after the charter, and any overage is settled before disembarking. A preference sheet built around long passages and rare vintages spends differently than one built around a quiet bay, which is why the same yacht can produce very different APAs in consecutive weeks.
VAT Follows the Itinerary
Within the European Union, VAT applies to the charter at the rate of the country where the charter begins, commonly 20 to 22 percent in the western Mediterranean as of this writing. Itinerary design therefore has a tax consequence, and experienced brokers plan embarkation with that in mind. Most Caribbean cruising grounds levy far less or none, which is part of the winter season’s arithmetic.
Gratuity Is Discretionary, and Expected
Crew gratuity is at the charterer’s discretion, guided by the broker, and commonly runs 10 to 20 percent of the base rate depending on region and service. It is given to the captain at the end of the week and divided among the full crew, including the engineers and deckhands the guests rarely see.
The Contract Does the Work
The MYBA Charter Agreement settles the questions nobody wants to negotiate mid-week: what happens if the vessel suffers a breakdown, what a cancellation costs and when, how weather diversions are handled, and what the owner warrants about the yacht. A charter broker earns their place twice, first matching the boat to the party, then walking the charterer through those terms before signature rather than after an event.
A charterer who runs this arithmetic before signing spends the week thinking about the itinerary instead of the invoice.
