Abstract
Method performed by a first communication device (101) operating in a wireless communications network (100). The first communication device (101) obtains (201) a first set of one or more values indicating an observed speed of a boat (151) relative to a power of an engine (161) of the boat (151). The speed and the first indication are obtained by from sensors (171, 172) in the boat (151). The first communication device (101) then obtains (205) a second indication of an external factor on the hull of the boat (151) causing friction against water. The obtaining (205) of the second indication is based at least on: the obtained first set, and a reference. The reference is based on one of: a) a threshold, and b) a mathematical model. The first communication device (101) also initiates providing (206) a third indication of the external factor to a device (103), based on the obtained second indication.
