Your report has researcher syndrome. It is packed with lots of good info, but it doesn't go anywhere. Go back over it and ask yourself "what's my topic sentence?" Of everything I say here, this is the most important, and really needs to be addressed.
Pick some aspect of all that (manufacturing techniques, tricks, reporting, injuries, the culture of boarders, etc) and bend the speech around that one topic.
You might want to see if you can find a skateboarder to interview, to balance the research. At least look for some other styles of sources so your speech doesn't come out flat and one dimensional. Frex, there's a whole parlance that comes with boarding, and you barely touch on it. Judicious use of a few more street terms might punch up the speech a bit.
Finally, actually read that sucker out loud. I think it's a looooooong speech as written, and it'll feel like the Bataan death march giving it. Give the speech in your room and time yourself.
Hope some of that was helpful,
