Publisher's blurb:
"The Customshouse Raid" is based partly on the Zeebrugge Raid of April 1918, though signifiacntly modified to suit the 105 foot Schooner VINDICTIVE on a smash-and-grab night raid in the fog to destroy a smuggling operation. Involving 4 realistic sailing challenges for the approach and 4 more for retreating from the raid, it adds a solid piece of maritime mayhem to your campaign. This is designed to be knitted into an existing campaign, and so does not provide detailed NPCs or plot devices; the raid can be fit easily into the interests of other smugglers, legitimate merchants, or government bodies.
This fifteen page adventure should be enough to get you started with maritime mayhem in existing games without having to learn a whole new naval gaming system.
