Topic: Battle Riders & Tenders
I've been pondering how to do battle riders & tenders, as featured in Traveller. A battle rider is a full sized fighting ship that lacks a hyperdrive. Several riders dock to a tender, which has a hyperdrive capable of jumping with the whole ensemble. The tender may also include some repair and resupply capability.
After some thought, I've come up with the following initial idea. I'd love to hear any suggestions or criticism. Also, am I treading ground that somebody else has already done rules for?
== Construction ==
Effective hull size = ((t^1.3) + (n * r^1.3))^.77 (roundup)
t = tender hull size
n = number of riders
r = hull size of rider
(you can also get effective hull size this way: add up the total SUs of your tender plus all its riders, then find the next larger hull size that has at least that many SUs)
Tender must buy engines and hyperdrive using its effective hull size.
Tender must devote 5% of its actual SUs to docking arms, cradles, etc.
The number and hull size of the riders that it is capable of handling should be noted on the tender's data card.
== Docking/Undocking ==
Done during the end phase.
Undock: the rider is placed on the board in the same hex as the tender. Its initial heading and speed are considered to be the same as that of the tender.
If a rider and a tender capable of handling it are in the same hex, the rider may be moved from the board and marked as docked to the tender.
A docked rider may not perform any game function. It may not be targeted separately from its tender. If a tender is destroyed, roll at die for each docked rider. On a 1, it survives and is placed in the tender's hex as though it had just undocked. On any other roll, the rider is destroyed.
== Damage ==
If a tender with docked rider(s) takes damage, any damage roll of 3 is not applied to the tender, but is instead rerolled and applied to a random docked rider. (this seems fiddly, but I like the idea of riders soaking up some damage from the tender)
No idea about adjustments to ORAT or DRAT, if any.
I occurs to me that something like these rules could also be used to do tugs.
