Port A has a really nice marina out by the airport. For the life of me I can't remember the name. Rockport would be the best for haul out. House of Boats can handle a 41'.
Don't know much about CC. From the looks there is a nice marina there.
Me I would go for the Port A marina if they had a slip. Close to good eating,shopping for the ladies, and your place in Rockport.
A short hop out the marina and the jetties and your in the Gulf.
The next time we go over I can get more information for your if you like. We sail out of Port Lavaca. Not a fancy marina but a great bunch of dock mates. Shallow water so we have to motor quite a ways in the channel before we can do any real sailing. Winds are always in the wrong direction.
