Coralie flashed a roguish grin, spreading out one of her charts, "On our own that thing would mince our little ships, but together we have a chance."
"The treasure fleet itself is more or less impossible to take on. It sets off from here -" she tapped a port on the Western coast of Calarian territory, "-with three galleons and some escorts. Then it winds its way between their other island and mainland ports, picking up more galleons as it goes, before setting off out to sea. The galleons are obviously a major prize so they stay in port, loading up with precious minerals and other goods, until the fleet arrives.
"We, however, are going to play a longer game and set up here on the island of New Posud well ahead of the fleet arriving, when their guard is down and they aren't looking for suspicious people. In aid of that, on our way out of the circle sea we will load up with a consignment of muskets and Quinian woolen clothing. Muskets will be easy to sell but Quinian woolens? Who wants those on a tropical island!? That will give us an excuse to stay in town while the galleon loads up. When the ship looks fully loaded we start a ruckus in town. A big ruckus! Maybe set fire to something, start a riot, whatever we can to make the galleon crew worry about the ship's safety and put out to sea, along with the startled flock of merchants, which is to say, us! Once we're safely outside of the harbour, beyond the harbour chain and range of the fortress guns, we board the galleon and sail it to the nearest Doel Port before the authorities at New Posud have worked out what is going on."
She paused, looking between the Captains, "So, what do you think?"
