Information for key market sectors regarding pontoon boats?

I have been researching for hours on the internet for information regarding key market sectors of pontoon boats. I am doing a group project and my part is to find this information. I need to know the Age,Income, Geography,Demographics of the consumers. I am not looking for the information to be posted on here just a way to find the information. Of the sites I did find they want you to pay for them which is not something I want to do.
