Actually, I think
none of the ones I posted actually is RedJet4.
Look at the differences on these pages:
http://www.simplonpc.co.uk/RedJet2.html
http://www.simplonpc.co.uk/RedJet3.html
http://www.simplonpc.co.uk/RedJet4.html
The ones that are saling on the photo's, have a smaller cockpit with the three windows. Like the RJ3 has. Thus it IS the RJ3, The ones that are docked, are the older type, thus the RJ2.
Even though they are in Google Earth at the same time does not mean they are different ships. Those sattelite photo's are not all from one date. so infact the Cowes photo could contain the same vessels than the Southampthon one.
In fact, there are four raptor class ferries to be found on GE, but they only operate three, the Red Eagle, Red Falcon and Red Osprey.
So I think that both sailing ones are in fact RedJet 3 and the docked ones are both RedJet 2 and that #4 is not amongst them. (AFAIK they operate these three and that there is no #1?!)
Again, compare the front windows of the cockpit of the RJ's in my posts with those on the pictures on the pages I linked here. You'll see, they're not the RJ4. Guess I'll have to look harder. IF it is somewhere in there, I will find it!
