A glass boat is a great way to start. They are normally lighter and are easier to manage when starting out. I started in a old 16 ft lavro and it took some serious punishment over the years and never had any problems. Fiberglass is tougher than you think and it will slide through the tailouts where you will be pushing an aluminum boat. I sold mine a while back and will be buying a aluminum boat next but glad I started with the ol lavro.
