Readme:
Once unzipped, place the entire Sloop2 folder in your art/units folder. Then copy and paste the SloopLarge.pcx and SloopSmall.pcx into your art/civilopedia/icons/units folder. Then open up the Sloop32.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 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 second edition Sloop!

^A [Sloop] is a fast but tiny vessel used primarily for exploring. Due to its size it can not carry any extra units and has very limited firepower.

^A coastal city needs both $LINK<iron=GOOD_Iron> and $LINK<saltpeter=GOOD_Saltpeter> in its
$LINK<Strategic Resource=GCON_ResourcesS> box to build sloops.

^As new techniques in ship building and design emerged thousands of new designs were made for ships of every purpose. Although the massive, mutli-decked, armed-to-the teeth Ships of the Line were the main concern of Admirals and Royalty, smaller ships were definately not outdated. Tiny vessels such as Sloops, with only a single, miniature gun deck and miniscule crew were widely used in the Age of Sail as scouts, for hit-and-run missions and light raids. Usually these smaller ships were kept well away from the raging battles between Flagships, but should one be at hand they could also be very useful as diversions and sneak attacks.
