I've got pics of two that I'm familiar with on https://www.benjineer.com. Mine is a 17' center console, and my dad's is a 20' cuddy with inboard. Be glad to answer any questions. I'd prefer fiberglass for the Gulf. It feels more solid when you start hitting some decent waves. I think you want something with high sides and a deep V. I've been out in bass boats and my little 16' tin, and it's pretty intimidating out front. Especially when you've got 2' waves. The 17' is great for little runs out 10-15 miles, but you've got to really slow down when the waves get up or you get wet and beat up pretty bad. It's easy for one person to handle alone, not bad on gas or pulling. The 20' is a different animal. 4' waves are no problem. You do have to slow down, but it's a much smoother, drier ride. Look at the sharp V on the front though. It's an old, heavy boat on a a double axle trailer which is much less manueverable in tight spaces. Both of these boats have wood, and both have had rot repaired. If you've got the $$, get a newer one that has all composites (no rotting). Deep V vs Bay Boat is another question. Depends on if you want to do inshore fishing with a trolling motor. Deep V's have a high profile and get blown around by the wind. I tried a trolling motor on my 17. It was difficult to control if there was much wind and it's not a big boat as far as Vs go. You can, however, get bay boats up to 24' or so that can be controlled with a trolling motor. They're more like bass boats with a little sharper V and no carpet. You will still get wet and beaten up, just not as bad as you are now. Standing is not a problem in any of these, and I stand in my 16' tin as well.
One con of a fiberglass boat is the weight with regard to running aground. You can really get stuck, if you get in a shallow spot. I don't have that fear in my little tin boat. It runs really shallow, and I can get out and drag it if need be. A GPS map with a chart loaded helps keep me out of trouble though.
