Not many places on the open Bay will be have deep enough water to hold an 82 ft boat. 4 mile creek will be one of the best bets for him to find water deep enough to handle it. The Mack Bayou area also has some deeper water around some of those properties. Good luck.
Yikes! An 82 foot boat! The neighbors would NOT be happy. There goes the view. Our neighbor recent bought a 45 ft boat and he can't get it in the channel to his dock yet. We're not looking forward to the day he might be able to get it in here though. Who wants to have their beautiful bayou view turned into a view of the neighbor's ego, er, I mean yacht?
Although there might be some docks around the Mack Bayou area that have 5.5 ft depth, the channel to Mack Bayou and most of the other bayous on the south side of the bay, can get very shallow, especially in the winter. Even in the summer, the channel to Mack Bayou itself, isn't 4 feet.
But I do happen to know of a beautiful lot for sale in Freeport on LaGrange Bayou that has that depth and the channel is deep!! The shipyard is up LaGrange. PM me if you want more details.
