I can't tell you much, but I believe that the Wizard was once a US Navy fuel oil barge and was built in 1945. You might be able to find plans for the YO class somewhere. I might suggest that you learn how to do some plank on frame building.
Here is a link to some ready built model fishing boats. On the side bar to the right are additional boats. If nothing else, the photos seem to be reasonable reference sources.
