Alum Drift Boat Plans

I have a friend that wants to try building aluminum boats. He thought he might start with a drift boat. Anybody have any idea where he might get plans?
This post is very old I know but is interesting to me and who knows, maybe someone else. I just built a drift boat from a set of Glen L plans. It was the 14' drifter. I still have the plans and your friend could have them if he wanted . Jasper
