The FLFleetExt object contains a representation of a fishing fleet as constructed for the purposes of fleet dynamic modelling. This includes information on effort, fixed-cost, capacity, crew-share, metiers and variable costs.
The constructors return an object of class FLFleetExt.
effort
An FLQuant with the effort of the fleet. The effort can have any units (e.g. number of fishing days, trips, hooks,...)
fcost
An FLQuant with the fixed costs of the fleet. These costs should be given by vessel and the number of vessels by fleet must be included in the covars object.
capacity
An FLQuant with the capacity of the fleet. Same units as in slot effort must be used.
crewshare
An FLQuant with the crewshare of the fleet. Where crewshare is the percentage of revenues that goes to the crew.
metiers
A FLMetiersExt with information on the fleet's metiers.
name
The name of the stock.
desc
