Danger on the High Seas

From publisher blurb: This PDF is designed for the use of players and Game Masters (GM) in sailing and boating adventures. Like with all d20 supplements it is the duty of the GM to determine what material is appropriate in their campaign. Player’s may argue for the inclusion of some (or all) of the material in this book into their current campaign but as always the GM is the final arbiter of the rules used in his or her games.
