As of November, if you're talking the GIWW you have
marinas available at a days run till WHL 160, though you may want to take a short day between
Morgan City and there and stop at Cypermore Point. After WHL 160 to WHL 331 there are no usable
marinas directly on the GIWW.
The Mermetau River makes a good anchorage at WHL 202, and if you time the bridge hours properly, you can make Lake Charles with a few marinas. If you use Bridge Point, be aware they do not take credit cards. From Lake Charles, you can make Shell Island at the Eastern end of Sabine Lake. If your
mast is over 50 feet though, you'll need to notify the Ellender
Lift Bridge at WHL 205, at least 4 hours in advance for an opening. You might want to consider following the Calciseau River down to the Gulf and going
offshore to Port Aransas.
If you do stay on the ditch, you have a choice to make after Shell Island. You can make it a short day to the Taylor Outfall
Canal, just past Port Arthur, or, you can HOPE, you can get in next to the High Island Bridge. It's reported to have 6-8 feet of
depth, but I went aground with 4 1/2. Stingaree Marina is at WHL 331, which is about 3 hours past the Bridge. That leaves you a short run to Galveston. Haven't been south of there, so can't say about the facilities. Were I going south though, I would go
offshore at Galveston.
