I have got to lengthen a Raymarine HSB2 data cable between radar and
repeater tomorrow -Raymarine say don't cut it, but thats not an option for
me as I need to cut the plug off to get it through some small hole

Can anyone tell me the cable spec (No of cores, shielding etc) so I can go

That would be STP, Shielded Twisted Pair. Only one pair (two wires plus
shield).
