AIMING TO INCREASE SHIPS SAFETY RATE DURING NAVIGATION IN SHALLOW WATER (CHANNELS & RIVERS, ETC) AND TO REACH NEARLY THE LEVEL OF ZERO ACCIDENTS OR DECREASE GREATLY THE CHANCE OF ACCIDENTS, INNOVATION OF A BRAND NEW METHOD THAT HAS NOT BEEN USED BEFORE IN THE WHOLE WORLD, IT SUPPORTS THE USUAL METHODS USED NOWADAYS. IT IS A NEW PILOT AGE METHOD BY USING PILOT AGE MARKS (I LIKE TO NAME IT SEA STAR PILOT AGE MARKS) IT IS FIXED TO CANAL FLOOR OR BOTTOM OF CHANNEL OR -ETC AND IT IS EXACTLY ON EQUAL DISTANCES AND HAVE AN ENOUGH HEIGHT TO BE SHOWN VERY CLEARLY ON SHIPS ECHO SOUNDER SONAR) AT FIXED TIME INTERVALS WHILE SHIP SPEED IS FIXED (GPS ) SO IF WE IMAGINE THE IDEAL COURSE (DEGREES AND POSITION) WE MEAN THAT THE SHIP IS COMPLETELY SAFE, SO WE CAN CALL THIS COURSE THE OPTIMUM COURSE, SO IF WE THINK THAT THE SUN RAYS ARE PERPENDICULAR ON THIS OPTIMUM COURSE, IT WILL MAKE A SHADOW ON THE BOTTOM OF THE CHANNEL EXACTLY. SO IF WE USE THIS SHADOW ON THE FLOOR AS A COURSE COMPLETELY THE SAME OPTIMUM COURSE ON WATER CHANNEL SURFACE, IF WE CHOOSE DETERMINED POINTS WITH FIXED AND EQUAL DISTANCES AND FIX THE NEW CREATED PILOT
