Ok, I built a ship with alot of boarding parties...

[PvK]

There are other issues to ship boarding combat, as well, such as dealing with ship defenses such as control of doors, air lock, and life support, not to mention security devices, breaching the hull, remaining docked to the enemy ship as it tries to break free, and the need to deal with the alien environment, including different corridor sizes, artificial gravity, unfamiliar devices, etc.
