Fleet maintenance is a periodic fee that is paid off every 15 days by the fleet leader or its deputy. It depends on the amount of slots for members in the fleet.
The unit of measurement for fleet maintenance is the reporting period. Its duration is 15 days, first reporting period starts at the day of fleet creation. First reporting period - as a gift the type of maintenance - VIP.
Every next reporting period while paying you can choose a type of maintenance.
There are two of them - VIP and Standard.
Access to paying next period will appear in 5 days before the end of the current period.
VIP has a dynamic price and depends on the amount of places in the fleet. VIP lets fleet members use strengthened versions of fleet research. They can also change fleet bonuses at any moment.
Standard has a dynamic price and depends on the amount of places in the fleet. It gives access to the standard version of fleet research, but you can choose bonus type only once - while paying the maintenance.
The service price is paid for each place in the fleet (even if it is not occupied).
If you miss paying for maintenance, fleet bonus, as well as fleet mechanics - rating, the addition of rating in the competitions, and so on (except the clan fee), are blocked. However, the fleet stays in the game as well as distinctive marks/inscriptions near players’ nicknames.
If the maintenance isn’t paid within 2 months, the fleet is dismissed. In case of dismissal, the fleet disappears from the game, from all the ratings. Ex-fleet members receive the status “a player without fleet”.
