Newbie with questions on Seacraft 20cc

[Duckdogsga]

Here is my situation. I am looking to purchase a boat for fishing and have always heard about Seacraft. I fish mainly inshore for reds, trout, occasional tarpon etc off the coast of Ga which is heavy barrier islands. I generally don't go offshore more than 2-3 miles but will make runs 10-20 mile north and south. We do have some pretty large sounds to traverse and they are never flat and sometimes gnarly, which is why I don't have a lot of confidence in "bay boats". I will generally fish 2-3 people, occasional solo. I do like to throw a fly line as often as possible and will probably require a trolling motor because of the tides/currents in the rivers we fish. No "T" top.
What is difference between 20 master angler and sport fisher?
What is difference in older Potter boat and later 90's and early 2000's besides Tracker purchasing them?
What about the Lefty Kreh package with the coffin box? Does it provide the room up front for 2-3 anglers? Does it have the elevated foredeck?
Is the fore deck on elevated or flat. I have seen pictures of both. I like the idea of elevated fore deck for fly fishing. Is this feature specific to a model?
Leaning post or bar stool seat?
Live well and dry storage capacity?
Are the dimensions the same on all models and the gunwale heights the same?
Will they ride the same?
Anything you would like to add, I welcome to hear from the "professionals".
