Portable rod holders

I have a bass boat and am wanting some rod holders but do not want to have to drill any holes or have permanent fixtures. I could have swore that at one time I saw someone on the forum that welded and sold some portable rod holders that held two or four rods. Any one out there have any ideas?

go look at extremefishingconcepts.com
