Paying for a boat rental abroad: always choose the local currency
The card terminal offers to 'charge in euros': a common trap that costs money outside the eurozone, at deposit, balance or security deposit time.
Booking or paying for a boat in Croatia, Turkey or the Balearics (outside the eurozone) sometimes triggers a question at the card terminal: "would you like to pay in euros or in the local currency?" The right answer is almost always the same one — and it isn't the intuitive one.
The "pay in euros" trap at the terminal
This option is called dynamic currency conversion (DCC). It looks convenient — an amount shown directly in your own currency — but the exchange rate applied is set by the merchant or their bank, not by your own bank, and it bakes in a markup well above a standard conversion.
What the research shows about these fees
An applied economics study of this mechanism shows that dynamic conversion, by appearing to hand the consumer a choice, actually produces fees that persistently exceed those of a normal competitive market — precisely because the buyer lacks the information needed to compare the two options at the point of payment (Ewerhart & Li, Imposing Choice on the Uninformed: The Case of Dynamic Currency Conversion, Journal of Banking and Finance, 2023, see the study on Google Scholar).
The simple habit to adopt
At the point of payment, always pick the local-currency option (say, Turkish lira, or euros if you're already in the eurozone) rather than the conversion offered by the terminal. Your own bank then applies the exchange rate, generally far more favourable, with foreign transaction fees typically between 1.5% and 3%, against several extra points for dynamic conversion.
Where it matters most in a boat rental
This habit applies to every card payment abroad: the deposit paid at booking, the balance settled on site, and above all the security deposit, often the largest amount in the transaction. On a pre-authorisation of several thousand euros, the gap between the two options can easily run into tens of euros.
A habit that complements other protections
This reflex pairs well with the other checks worth making before paying abroad, covered in our guide to credit card insurance and boat rental: together, they help you avoid both a bad exchange-rate surprise and a coverage gap if something goes wrong.
