Who Makes The Widest Aluminum Boat What Is The Deepest, Widest, Welded Aluminum Boat Made In A 18 Footer?

What is the deepest, widest, welded aluminum boat made in a 18 footer? - who makes the widest aluminum boat

I was recently in Puget Sound in Washington and saw that it opened 2 bottles of workboats to a counseling center in the class of 18 foot. They looked like giant paddle boats. The faces were at least 5 feet high. I found the name or brand on them. Has anyone an idea?
