For a map that we're working on, we needed a symbol for a large river raft that hauls freight. Such rafts floated downstream and were pulled back upstream empty by draft horses on the river bank. As a prototype, we chose the river rafts that used to haul logs downstream on Northern Bavaria's Main River. Such rafts went out of business long ago, but the one depicted above at the Franconian Open Air Museum in Bad Windsheim served as our prototype. In the second thumbnail you can see the raster symbol that we made of the raft. It's available free for personal and commercial use under the Open Game License 1.0a. The raft has a size of 50x15 feet (15 x 4.5m). The scale is 40 pixels ' 1 foot.
