IMO an explorer-specific ship is something with a massively oversized FSD. Until FDev add some gameplay that isn't mind-numbing to the scoop-jump cycle, the sheer number of jumps and wasted time is the biggest barrier to most people leaving the bubble in any meaningful way.
7A frame shift drives exist in the game and have a mass of 104T at maximum engineered range, yet the only ships we can fit them too come in at vastly more than 1000T. If all the combat ships sacrifice jump range for firepower, why can't we have an explorer ship that sacrifices firepower for jump range? There's no need for FDev to force ridiculously heavy C7 power distributors (80T), life support (80T) or sensors (80T) on a ship that will not be used for combat. Give it rubbish hardpoints, utility mounts, a combat-unsuitable power distributor, and limit cargo bays because explorers aren't cargo haulers and needless hull mass to support unused cargo bays hurts jump range.
