I found this one, not sure which of the Red Funnel ferries it is, maybe a sister ship to the Red Eagle

Just up the river, at the entrance to Southampton you can spot another Red Eagle sister, maybe even the Red Eagle itself:

Then, even further up the river to Southampton, you can see a third Red Funnel ferry.

Then, strangely there is a fourth one. The only possible explanation is that the images were taken at different times then joined together.

However, i can't find the Red Jet 4 on Google Earth. Maybe these images were taken before the Red Jets launch in 2002/3?
