ADAM SHEPARD's page

So I would like to add some diversity to the Ship types (Junk, Longship, Sailing Ship, Galley, and Warship), I'm looking for Stats for a Frigate, Galleon, Ship of the Line, Sloop of War (a regular Sloop would be the Sailing Ship right?), Turtle Ships, or Has any one converted the Fire As She Bears or the Skyborne Ships to the standard Pathfinder Rules? Also has any one created any other Unique Ships? Or Ships created by other races? Any help would be appreciated

I have been trying to reverse engineer the IMPERVIOUS from Pathfinder Campaign Setting Ships of the Inner Sea (page 33) which is stated as a 4-squares sailing ship, instead of the 3-squares average ones introduced at the Player's Guide.

Hello.

I have just noticed that the IMPERVIOUS, which ship statistics are shown at Pathfinder Campaign Setting Ships of the Inner Sea (page 33) is stated as a 4-squares sailing ship, instead of the 3-squares average ones introduced at the Player's Guide.
Since then, I have been trying to reverse engineer the IMPERVIOUS ship's base cost, but so far I have come up with odd numbers that don't really make any sense.
Can you help me to come up with the actual cost of the base 4-squares sailing ship? Is there any system to build even larger ships, such as the Black Pearl?

Thank you!
