Readme:
Create a new folder named 'Fluty' in your art/units folder then unzip all the files into that new folder. Then copy and paste the FluytLarge.pcx and FluytSmall.pcx into your art/civilopedia/icons/units folder. Then open up the Fluyt32.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! 

Note: As usual there are two versions of the civilopedia text, the first one is for my mod and the second is the standard one.

^ A [Fluyt] is a ocean going transport of Dutch design. It is slow and weak but has a large cargo capacity and is very cheap to build and maintain.    
^
^A Dutch coastal city needs both $LINK<iron=GOOD_Iron> and $LINK<saltpeter=GOOD_Saltpeter> in its
$LINK<Strategic Resource=GCON_ResourcesS> box to build a Fluyt.

^
^ The shallow waters along the dutch coasts pose a rather irritating problem. Large, ocean-going trade ships tend to have rather deep drafts and so run aground several kilometers from dutch harbours. To maintain trade ships would stop well outside of the shallow waters and rowboats would travel between the ships and the coast at painfully slow speeds. This noticably diminished both the speed and amount of trade between the Dutch and other countries, particularily Canada which uses almost extensively deep drafted vessels. The Dutch quickly realized their dilema, and the solution was a some what revolutionary ship design, the Fluyt.
^
^ The key to the Fluyt's innovation is it's abnormally wide hull, giving it a very shallow draft do to the ship's mass being displaced over a wider area. The shallow draft makes this vessel very slow and almost hopelessly unmaneuverable, but allows it to travel in almost any waterway that's wide enough for the hull and also gives the ship immense seaworthiness. Fluyt's are very easy to handle, allowing much smaller crews and so far less expense. The vessel suffers offensively and defensively from this design, but is not entirely helpless. A Fluyt comes armed with a few cannons on its main deck that serve enough of a punch to make the vessel a decent warship in desperate situations. A victory over another ship with a Fluyt is a great feat of skill in nautical warfare, so much so that the larger navies often purchase retired Fluyts to be used as training vessels.

The armoury of a Fluyt is it's most significant cost factor, and while they are no where near to being 'armed-to-the-teeth' with a well trained crew a Fluyt may be able to fend off an attacking vessel, under good conditions.
