I thought it had been discussed here, but I can't find any suggestions on making a Docking Clamp vehicle attachment. What I'm looking for are clamps for external mounting of another vehicle which still allows it to travel with penalties applied. Not a soft docking tube. Any discussion on limits (how many vehicles, limits on silhouette) and penalties (speed? handling?) would be appreciated. In RAW the only reference I could find is a description of the Citadel in Edge Core, a silhouette 4 ship, that can carry two silhouette 3 fighters attached to it. So I would want to be able to emulate that even if it takes further modifications to increase the silhouette or numbers carried.

1,000 credits, acts basically as an air lock connection and hyperdrive sled. No hardpoint costs, grey box in the vehicle chapter of edge of empire.

Should imho not including refuelling or other options, just the dock and transportation options. Would be a good moment to hand out setback dice when actually flying around, same as cargo containers.

Technically page 258 says you can handwave it.

Though if you gotta make it an add-on I'm with Sea and don't make it a complex HP using thing.
