SAI was never intended to model raiders beyond the North Sea, Baltic and the limited RJW
guerre de course by the Vladivostok cruiser squadron.
As for Jutland, it's pretty much useless since you cannot edit the campaigns and all scenarios need the opposing sides to be in contact for the scenario to actually run. Without the excitement of the hunt, virtually all raider combat situations are forgone conclusions for one side or the other.
I quite enjoyed the board game
Raider but it is for WW2 and exclusively Indian Ocean. I still have the game but alas, no local opponent.
Every now and then I will fire up
Great Naval Battles North Atlantic, which still has its charms and often demonstrates the "Raider's Dilemma" pretty well.
