Someone had mentioned Lund Renegade in another thread and I thought "never heard of it" so went to their website.  Sure enough, there it is.

http://www.lundboats.com/boat-series/renegade/

Is there a question, or a topic to discuss?

I did a quick search and didn't find if this is a welded or riveted boat 

I didn't see anywhere it was mentioned either. But on that page you gave a link to all the way at the bottom they have a "Ask a expert" thing where you can ask them anything you want to know.

The best part is there should be no question what ever answer you get will be the correct one. Unlike asking in a forum where who knows maybe a dealer rep answers maybe a 15yr old answers.
