I will be staying a house in Sea Isle on Galveston Island over new years and will have my boat with me. It's a 20' blue wave pure bay was hoping to run from Sea Isle to the intracoastal but don't know the area. I've heard horror stories of west bay and would simply just cross the damn thing safely. I have a garmin echo map with the latest chart update subscription for the area but not sure how accurate those are.
