From publisher blurb: This is the 2nd edition rules for Arrghh Bottom Sound - improved and streamlined to make it easier on the GM and the players when looking for rules. Unlike the first edition, this set of rules does not include scenarios, but it does have a list of monsters and their stats as well as complete rules for the operation of sailing ships and sea battles. The rules are an improvment from first edition, with a lot of streamlining and simplifying but those familiar with the first edition wll find the core game remains the same.
