Category:Hit dents on screw blade R1
The screw blade R1 of the right screw of PCC-772 has hit dents made by neighboring screw blade R5. There are 10 or more of individual similar indentations. This means that the right screw of the ship had rotated 10+ turns while deeply and forcefully digging the seabed, after all or most of its blades had been already bent by the same cause.
Comments added by the author: There's some scarce but not ignorable possibilities that other environmental or passive (I mean 'unpowered') effects could have caused the same or similar effects described above. For example, side skidding of the ship on the seabed after sinking by the strong sea currents of the site known to reach about 3 knots or so. (Sep 14, 2012)
