'Rules Light' doesn't mean that they have neglected the rules, just that they are streamlined and unobtrusive, unlikely to get in the way of best-quality pirate role-playing action!
You get everything that you will need to unleash a band of pirates across the ocean quickly and simply. Characters are generated by describing them, the only numbers you need are level, armour class and hit points. The rest flows from the class and special abilities that you choose for your pirate. Accompanying notes encourage you to enable creativity (especially if you have youngsters trying their first hand at role-playing) by letting players have any ability that they can articulate, or be of a different class that they come up with, showing you how to assign skills etc. in a balanced way by mixing existing rules as appropriate.
Combat, indeed any task resolution, is handled simply as well with an eye to keeping the action (and the excitement) flowing... and yet there is scope for plenty of detail if that is how you like to play, special moves, different damage depending on weapons and much, much more.
There's pirate ship-to-ship combat as well as the up close and personal variety, which can be conducted in a fast, abstract manner or in as much detail as would satisfy any board wargamer's heart, depending on what you and your group prefer. There are also some beasts, and the scope for magic, undead, and other fantasy staples. Although these are presented as inherent, you could excise them quite easily if it's 'real' pirates you are after rather than the fantasy variety. Given the apparent Caribbean setting (this is assumed rather than mentioned outright), there's Voodoo as well. And legendary monsters like the Kraken to come and wrap its tentacles around the pirate ship.
There's a surprisingly sensible section on Pirate Talk, providing some proper nautical jargon and pirate terms as well as pointers to develop the correct silly accent if you want to go Arrr all the time. Details of special treasures, a detailed skill list and a selection of character sheets round this out.
Don't be deluded by 'rules light' or a preponderance of pirate talk, this is a solid, quite elegant, role-playing game based around that ever-popular thing, the pirate in the age of sail. If that appeals, do try this out. You'll have a blast.
