At last, Thieves' Guild has gone to sea! Here are complete rules for designing and sailing ships, for sea chases and bloody boarding actions, and what's in the holds of the wallowing merchantman you just overhauled and captured.

And ... lots of encounters at sea! Ships by the score! Broad-beamed merchantmen loaded with luxury merchandise bound for exotic ports in faraway lands, or wondrous treasures to enrich the coffers of powerful empires! Slim deadly warships, to guard these golden argosies, or to seek freebooters out in their own lairs and put an end to their larcenous careers! Even fellow pirate vessels, to sail with at sea or to sail on!

Merpeople, herds of whales, world-lashing storms, exotic uncharted lands, omens of disaster and great good fortune, even sea-serpents will be met in the pages of Thieves' Guild's latest triumph.
