Err Folk, Cairo is a long way from the Red Sea, took us 5 hours in a coach complete with armed escort. The med is slightly closer at 90 kms to Alexander and much more pleasant.
The Nile at Cairo looks like a wide slow moving river with reed beds thats full of polution from the city. There are large boats that wouldn't look out of place in a Hercule Poirot plot, but I wouldn't want to get to close to the water. Stick to the Pyramids and the Museum but only drink from cans in the museum cafe
