Readme:
Create a new folder, Schooner in your art/units folder and unzip all the files to that folder. Then copy and paste the SchoonerLarge.pcx and SchoonerSmall.pcx into your art/civilopedia/icons/units folder. Then open up the Schooner32.pcx with an image editor, back-up your units_32.pcx and open it with an image editing program. Paste the image into a square at the end of the other icons, be sure to line it up correctly. Finally, backup your PediaIcons text and Civilopedia text. Then copy and paste the appropriate text below into its respective places (feel free to change the Civilopedia description, this is only my version). Finally, open up your scenario in the civ3-editor and add the unit (if you need help with this part, look around in the tutorials forum, I made this quick tutorial because some people organize their units differently).

Enjoy!

^ The Schooner is characterized as having at least two masts with sails running along the ship length wise. They were originally made by the Dutch in the 16th century, and were later used heavily in North America, by the late 1800's at least 2000 Schooners were in use on the Great Lakes. Likely the most notable schooner is the Bluenose, and its sister/replica the Bluenose II.
