Also note that the boarding attempt is made before weapons are fired. What does this mean? shield regenerators will make a ship invulnerable to one-on-one capture attempts. This is because the targets shields always regenerate a bit before you can board and you have to wait till next turn before you get another board attempt. Viscious circle ain't it?

So always make sure that you have at least two shield depleter boarding ships (or at least another depleter equiped ship) so that you can tag-team and get past that annoying glitch.

It may be because AI "fires" weapons according to its placement by design.txt file. Usually boarding ship has "boarding attack" as a "must have ability", which is also "majority weapon". Thus, ship tries to board first and only then uses "secondary weapon". Try "must have" to be a "weapon" (with appropriate weapon number as a majority component and "boarding attack" being one of miscellaneous abilities. If it does not work - ship does not board at all - simply add "boarding attack" as miscellaneous ability to the existing ship design. May be it will try board and fail, then will use weapons and board again !
