P&O Ferries has imposed a ban on 200 students after staff and passengers complained about their drunken behaviour on a cross channel ferry.
Some students exposed themselves while a fight also broke out in a bar on board the Spirit of France ferry on April 1, the firm said.
The University of Manchester and Manchester Metropolitan University students were travelling to the Alps to go skiing.
About 1,559 people were on the vessel at the time, including young families.
A spokeswoman for P&O Ferries said the company had contacted the universities and their tour operators and would not be providing transport home for the groups.
She told the BBC: "The company deplores the behaviour of this group of students, who were clearly drunk before they boarded the ship.
"Customers and staff on board the ship were appalled by the students' aggressive and lewd conduct, which should be stamped out by the authorities."
