In my experience that's exactly how boarding works no matter how few or many boarders you have. The more and better boarders you have the greater the chance for succes. I have failed to board ships sometimes. If you want to board more than one ship, bring more ships with boarders.

FYI, I don't really like how boarding works, but I can live with it. To make it work like I want it to crews would have to be added along with a bunch of other stuff.
