Here is Willie’s cell phone number - (228) 216-1307. Like I mentioned in my post, he is the Harbormaster in the Pass.
Tell him you got his number from Shawn Wozencraft (formally with Thompson Engineering). I was the PM for the design and construction oversight for the new portion of the harbor that was built after Katrina. I worked with him for 3-years. He’s a good dude and will be able to provide you with any info you need on Cat Island.
