Just got 22 ft Skeeter Center Console and want to take a ride down Blind River to lake Maurepas and then across to Pass Manchac to Middendorfs. Have been in Blind River alot but never crossed the lake. Is there any main channel marked or navigation issues that I need to be aware of? Also, is St. James Boat Club launch open to the public - for a fee I am sure? Any advice is appreciated!
