Corpus Christi should diffidently be on the list of places to look. There are several
marinas around Corpus Christi Bay that should be workable for a 44 foot trawler. The Corpus Christi Bay is easily deep enough for a 5" trawler to go just about anywhere.
Look at the Corpus Christi Marina. It's right near down town Corpus Christi, and is VERY nice. Restaurants,
shopping, buses, the USS Lexington warship Museium, the
Texas State Aquarium, a concert hall, baseball part, etc, the city is pretty much all there.

The Port Aransas Marina. It's basically in Port Aransas, which is an excellent little tourist town, with the typical
Texas Island shops, restaurants,
fishing, beaches, etc.

The
Bahia Marina &
Dock Store is also worth a look.

Any of these should be roughly a 3 hour drive from San Antonio. Each has a somewhat different "flavor", and is worth looking at.
There are other marinas, but I just don't know much of anything about them. One would be the Island Moorings Marina on Mustang Island.

The entire Corpus Christi Bay area is interesting for all sorts of water sports. Kite boarding, sailboat
racing,
fishing, beaches,
food, on and on. I would easily argue that the beaches on Padre Island and Mustang Island are far superior to just about anything along Galveston or Matagorda.
However, due note that the Corpus Christi Bay tends to be windy.
