These holes intrigued me for a long time when I came aboard the s/s Norway in 1999...
Is that in correspondence to the evacuation of the water of the window of the bridge provided with a windscreen wiper and which could open down in the wall?? Is thatcoming from the roof of the bridge?? Windows with windscreen wiper gyroscopic?? From the floor of the bridge wings??
These openings were present on the s/s France as on the s/s Norway... In 1999 as in 2003 there was some rust in every opening because the water stagnated there..
On a ship: we always scratch the rust and we always repaint... The water infiltrates everywhere..
