The RIB you are interrested in looks a bit like mine, which is also from origin a chinese build.
But mine has a very clear much deeper V hull, with a total lenght of 4,7 mtrs.
And like that one, quite long tubes behind the transom, so internal lenght is simalor to a 4,5mtr RIB.
Ofcourse my RIB is not like the quality of a humber, osprey etc etc. No hypalon and the finishing detail could be better. On the other hand, the smaller zodiac's usually aren't hypalon either and have a less deeper V hull.
The price / quality of my RIB is right were it should be.
