Stringy print results

I am using a wanhao duplicator i3 and I printed the 3dbenchy. While I was printing it I realized that the results were really stringy and the botom wasn't there. I printed it with a raft, 50mm per second, and I was printing at 210 degrees. I cannot upload a picture because my computer is not allowing me to. Any suggestions on how to fix this issue? I am using e-sun filament.

Not sure what slicer you're using but this has some great tips for ooze/stringing.
