I cant believe that a state funded project would use a fly by night company that did not display any of the internationally recognized symbols and shapes that are used to help boat traffic understand the situation and circumstances concerning the dredge work taking place !! They had a small cardboard sign that read " stay on this side ". When the dredge is facing south that sign will but you in safe deep water....but as the dredge pivots and faces north that sign puts you on the opposite side in very shallow water !! We alerted the coastguard and I'm sure that company will be in deep poo poo !! We wont be the one who sue for damages...but I'm sure others will !!
