I was stationed at Naval Air Station corpus and kitesurfed laguna madre for three years. It was very shallow except for the narrow channel cut out for barges. I’m currently sitting in Cancun on a layover (airline) and fly this route from south Texas coast to Cancun frequently. I’ve never seen a cruising sailboat along the coast, and I look often. It’s hundreds of miles of beach, warm waters, and steady south east breezes. I did get my ASA 101 in corpus, and I know the bay is great sailing, but don’t know of any making voyages south. I’ll keep looking
