 |

So, playing around with another idea, I was also thinking about multiple ships, traveling together (Luke mentioning the TIE Fighter having been part of a Convoy, or the Rebel Fleet arriving together above Endor).
How do you manage that? I'm picturing the Millenium Falcon (*.5) arriving at the same time as a Corellian Corvette (*2). Core astrogation rules suggest that the Falcon simply reduced its astrogation difficulty by a lot to arrive with the Corvette... if Sullust is 8 hours away, the Corvette was going to take 16 hours, the Falcon was going to take 4, and so the Falcon dropped its astrogation difficulty by 12 to keep everyone together.
However, if you have someone, say, flying escort to a ship on a hyperdrive backup, that's going to result in a lot of extremely low Astrogation numbers... which would imply that you're taking a different route than your charge.
Can you throttle back your hyperdrive to the lowest common denominator? Does that result in the easier astrogation roll?

That makes sense. Just because an A-Wing can fly at Space 12 doesn't mean it has to.

Yup. And its not just with convoys, but in mixed group fighters going to a common battle point.. B-wings are X2, while A/Y and X wings are all X1.. So if a mixed wing (2 B-wing squadrons, 2 Y-wing, 3 X and 1 Awing) were all heading off to smack imperial facility 123.345, they would all go at X2.. Unless the B=wings leave earlier, and the others go at regular speed later, so they all arrive at the same time.

Yes, and there already is a mechanic for that in RAW. R&E p. 115:

I already mentioned that. In the post you quoted.

You asked two questions in the post I quoted. I answered.

I'm going to wade in as a voice of dissent.
I believe that you can 'dial down' your hyperdrive rating to match a slower craft, but I do not think it should result in easier astrogation.
As far as I know, the astrogation roll represents selecting the most efficient route through the myriad hazards of realspace that leave shadows in hyperspace. If you roll well, then you have selected an efficient route; shaving off time by 'squeezing' past hazards that poorer astrogators give a wider berth for error.
So, it seems reasonable that ships in convoy are going to all take the same route. Ships with a better hyperdrive rating are not going to have an easier astrogation difficulty just because their ship is limiting its transit rate of the selected route.
I see a convoy making a single astrogation roll at one difficulty based on the efficiency/risk of the intended route and then transmitting the computations to all the ships in the convoy.
Faster ships are then free to dial down their hyperdrive for the transit. |

Hmm.. Interesting POV on that. Which brings up the related q of which ship's doing the astrogation roll in the first place in that 'mixed convoy'. The slower one, or the faster one??

Well...I'm thinking the one with the best astrogator most likely.
In a convoy, probably the command ship. Determines the route, makes sure that the calculations get downloaded to everyone. This will be another step that the GM can influence...how long does it take to get everyone on the same course solution.
They synch up their hyperdrives to the rating that they'll all be travelling at...ie if the slowest transport is Hyperdrive x2 then everyone sets their rating to x2...and then off they go.
If a convoy got attacked while mustering for a hyperjump it begs the question...does every ship make their own jump and scatter for survival, or do they wait for the command ship to download the route and take the beating until its ready?
Like in that Battlestar Galactica episode when the Cylons were always like 20 minutes behind them, which was just about the same time it took to get the fleet ready for the next jump. |

I would say they would all make a pre-planned emergency jump...

Which is why i hated that episode, that they Waited till the Cylons jumped in before scramming.. IMO they should have done 2-3 STRAIGHT jumps before settling in.

It has been a while, but I think there was a definite delay to how fast they could make the calculations and disseminate it to the fleet...that was just about on par with how fast the Cylons could calculate where they went and go after them. |

I would rule yes, for the very reasons that you indicate. Hyperspace fighters running escort would logically follow the vehicle they are protecting so that if it drops out of hyperspace, they will likewise drop out of hyperspace to defend their client. To accomplish this, they will have to match the hyperspeed of the vehicle in the front of the convoy.
As for changing the difficulty I would rule no. Navigation is navigation and you are computing a vector from point A to point B relational to the rotation of the galaxy being that the core of the Galaxy is rotating faster than the outer rim. The only time I would rule an improvement would be if someone rolls a successful command roll and multiple ships are coordinating their skills to obtain coordinates for the jump.

ON the time, iirc making the duration of the trip slower, makes the astrogation roll easier.. OR you can hasten it by making the diff harder..

Yes, as already discussed with specific rule citation above in this thread. You don't reduce hyperdrive multipliers, directly. The slowest ship comes up with a duration for everyone else, and then the other ships add hours to their duration until it equals that duration.
I'm baffled by those saying going slower shouldn't be any easier. By the existing mechanic, adding more time lowers difficulty and subtracting time adds difficulty. For those saying it shouldn't be easier to go slower, have you house ruled away the RAW about increasing or decreasing the duration of hyperspace journeys? What was your reasoning?

We're more asking WHICH ship in that mixed speed fleet, is the "Key point" for making the astrogation roll. The slowest? The fastest? The one with the nav comp??
