My earlier response sounded snippy - was not intended to be. I was in a hurry. Sorry.
Our boat is at Blue Dolphin in Kemah. Good facilities, good pricing, and just on the north side of the big Kemah bridge which can save you 20 minutes alone during peak traffic times since you will be headed north anyway. There are a number of live aboards there and a friendly marina community, too. We live way up north just 10 minutes from the airport; our commute is south to the boat on the weekends.
