Edit... for final findings click here Sea Dogs You have to be adjacent to the required ship You will have a % chance to capture the ship when normally you would destroy it. (it comes up with a message in the combat box only on the killing attack) The % chance is the same as your base strength so wether 50%, 60% or 67%...but also modified by relative strength(not enough tests done) You can capture ships from any era You cannot capture non military ships You cannot capture Barbarian ships They do not count as Military ships for upgrading XP by admirals but do count as a military ship for the armada adrmiral - Santa Cruz I have had a weird one trying to capture a sub ... When I have 2 sea dogs nearby the sub moves away and when I attack it it only gets damaged and in their turn they delete the sub! If I have 3 sea dogs nearby they delete the sub. I have restored 3 times and scoured within the 4 MP range it has to no avail and so must assume deletion. As not all sea dogs are within sub visibility I am uncomfortable that the AI seems to be doing this.
