same reason you do not have drying hights to the shoreline or over sand banks or rocks. who is going with 2000000000000000000000 tons tanker over sand bank or 10 meters from the shore of river bank. for those kind of "boats" there not enough deep anyway even on spring tides. you are simply avoiding it
