Capturing ships

[unmerged(239788)]

Every once in a while my fleets will capture ships in sea battles. Is there a way to increase the odds of capturing enemy ships?

Does a high Martial admiral help? Anything? At 10$ a pop capturing ships is preferable to building them!! LOL

It seems to be almost entirely random to me. If there's a connection to any of the characteristics, then I have not noticed it (but this does not mean it doesn't exist!).

Although I do seem to get a disproportionate number of captured ships when fighting pirates. As such, I always engage pirates whenever I can, even if they aren't bothering me directly.
