Amateurs.
Real explorers use Federal Dropships or Corvettes - with military armor and heavy weight mods![]()
(Dolphin is a nice ship, too bad it doesn't like planetary flight. Orca is nice too, and the Beluga. Ships for those who like luxury and don't care about the stuff peasants care about)
The advantage with short jump range is LOTS of star systems to honk. I made most of my exploration rank by going to Colonia in a T-9 with only 14ly max jumps. Seriously, don't be in such a hurry to go 1000lys. Use economical jumps and rake in the cash!
