I am interested in gathering opinions on purchasing a new boat in the 18' to 20' range. I will be fishing around Port Aransas in the bays as well as fresh water lakes. I have been looking at Express bay boats and Excel bay boats which are aluminum. Does any one have personal experience with the aluminum boats. They are $3000.00 to $4000.00 less expensive than fiberglass equipped with the same features and engines. Thanks in advance for your replies.
