Donald,
You need at least five boats to cover most every situation. But most of us get by with 2-3! What are you looking to do? How many people, decoys, dogs? What kind of water? Dedicated to one situation or do you need versatility?
Let us know what you are looking for and what you expect it to do. Going to the Tuckerton show is a great idea! You would see many hunting boats on display, not just what the newest thing on the market is.
