There is a remastered version of both Homeworld games and it seems like there have been some changes. If I remember correctly, very few enemy ship types could be captured using Marine Frigates in the original Homeworld 2. I'm now replaying the Remastered version and having trouble capturing a Vaygr Carrier in mission 3. Posts on the internet confirm this is not just me. Before I invest in Marine Frigates, which ships are known to be capturable, and which are not?

Retiring ships commands them to be deconstructed and credit you with some RUs. It's like recycling them, so the resources can be used to create something else. This is exactly the same behavior as in the original Homeworld.
From the Homeworld one manual:
Bring up the right click menu and select the Retire command. Ships given the Retire order will return to the nearest Mothership or Carrier and be scrapped. A percentage of the construction cost (in RUs) will be recovered. OR: Press the [I] key once you have selected the ship(s) you wish to retire.
From the Homeworld 2 manual:
This is not 100% of the construction cost. I understand it's approximately 80% of the construction cost.
I know that you don't have to pick up all the resources at the end of a level (if you wanted to max resources that is) in HW1 anymore as they are auto-collected. Great time saver imo.

In the HW2:RM (and original HW2) campaign, you can't capture enemy production units (carriers, facilities, motherships etc). Destroyers and hyperspace gates and I think resourcing units too are all fair game though. Also I don't think you can capture corvettes or smaller but I'm not 100% sure on that.
Finally, unlike HW1/HW1:RM, you can't capture units above your unit cap.
