Today the thought occurred to me: "Which ship has the lowest jump range, even when maximally optimized for it?" Then I thought, why not rank every single ship based on that, and make a sorted list? So I did a bit of testing at edsy and created the list.
Approach: Only jump range matters, ie. only optional modules that affect jump range and nothing else (which in practice means the only optional is a guardian FSD booster). From all the other modules, the lightest one that doesn't have a red warning symbol on edsy. Besides engineering the FSD (or using the 5A FSDv1 if applicable), full engineering for weight on everything, of course (ie "lightweight" or "stripped down" experimental, whichever applies). Lightest power plant that can power up everything (with "overcharged" engineering as needed).
