50 Fathoms Explorer's Edition Player's Guide is a nice little book of nautical heroism for the Savage Worlds system. It introduces a hefty selection of new Edges and Hindrances, gear, and setting rules that really bring out the swashbuckling theme. There is a whole section on ships including deck maps, mechanics on how to navigate and sail them, how to crew them and how to make sure the sailors get paid enough to not mutiny.
The included setting of Caribdus seems a bit like a aquatic-themed D&D. There are eight new races (not including humans) which makes the world feel rather cramped to me, especially given the small amount of dry land available. The setting is definitely high fantasy, with a few new appropriate spells and spell trappings. These elements are easy enough to strip out if you wanted to run a mundane swashbuckling campaign, though. I could even see these rules being used to run a steampunk style game, with flying galleons and sky pirates.
Basically, 50 Fathoms EEPG is a great resource at a great price for players and GMs looking to add some high seas adventure to their games.
