Many factors go into answering your question. How often do you plan on fishing. What type of structure will you be fishing ect. I fish out of a 22' center console and love it. Best answer I can give is stay within your budget and get all the boat you can. AlliUminum is better in timber fiberglass better in open water. Longer is better than shorter. All boats will float. The skill of the angler is what catches fish. Not the boat.
