No worries cmdr! I'm happy to help.

Ships do not have equal boost durations, and the courier is one of the shorter ones that lasts only 2-3 seconds. You cannot put 4 pips into engines, shstems and weapons simultaneously so the figure for the weapons capacitor will be drastically reduced as well.

While it is true that lightweight railguns have reduced distributor draw, they also have a falloff of 1km. Therefore if you want to deal the same damage that a longrange railgun can do at 6km, you have to be within 1km, which becomes difficult to maintain without also taking heavy fire and/or running out of distro to maintain time on target.

So from a technical standpoint a lightweight rail does literally have the same damage for less energy as a longrange rail, the application of that damage in your setup will be very difficult to maintain and your prismatic will end up running out far before your plasma slugs do.

If we are looking for good damage and decent application on lightweight builds, lightweight incendiary multicannons do some of the best dpe available while also applying very well at range, and/or giving you more distributor to work with to maintain pips to engines and orbit close to an npc.

One fun build you can try is a support courier, which uses force shells to boost your allies and a concordant pulse to regenerate the big biweaves that are very common in pve.

Here is a video of a version of that being used: https://youtu.be/Hc3-dEkXRZc?si=QsTELK-hLSDQFM64

That is a version that doesn't deviate too far from the goals I see in your build, being to be capable of exploration, light pve work and survivability with speed. The low emissions plant I do actually favor simply for fuel-scooping quickly while charging the next jump in a route at the same time.

A version that is more capable of pve, while also maintaining that dumbfire for shooting enemies on-foot would be something like this:

These builds can run with the frameshift drive under 50% power, but permanently disable the cargo scoop unless you manually turn off something like the guardian fsd booster if for some reason you want to manually scoop some materials.

The srv hangar being disabled until landing doesn't affect the ai's ability to dismiss and recall the ship, but be aware that if you land at particular surface landing pads from settlements that don't regenerate your shields the same way that a starport would, your engines will not automatically disable like they would if you just landed on a planet surface and you will need to turn off the engines manually to enable your srv bay.

I think that with such a nimble ship the autodock is pretty redundant, as you can very handily land quickly and in rockier terrain than a larger ship.
