    Hello guys,
    I will appreciate if you could help me, i am trying to calculate the Gross tonnage and the Net tonnage.

    but, when i see the formula my doubt is :

    N1 = number of passengers in cabins with not more than 8 berths,
    N2 = number of other passengers,

    What does other passengers mean?

    Coul you tell me examples related to N2?

    Best regards.

    Means passengers who do not have a cabin or passengers in cabins with more than 8 berths (not so common).

    Consider, as an example for N2, a short route roro pax where there are a few cabins for the drivers but most of the passengers travel in common spaces...

    N1 = number of passengers in cabins with not more than 8 berths,
    N2 = number of other passengers,

    A railroad example;
    N1 passengers who reserved a sleeper car.
    N2 passengers who have to sleep sitting up
