@ all Thanks everyone.

je crois que le terme correct c'est " onzième touchée"

Nikki Scott-Despaigne Jun 27, 2018:

Context If Kevin is correct, and he may be correct http://www.cnrtl.fr/synonymie/toucher au port/verbe , then it might mean that if a particular vessel is a regular visitor to the port in question, the first 10 times are charged at a standard rate, but from the 11th one onwards, they get a cheaper rate.
It might be helpful to provide an extract of your original document with the term in a complete sentence, or even with a little more text too.

La onzième escale ? Toucher un port = Call at a port
