Secondary Attack for ships

[rebelyell2006]

I had a thought for ships: the text descriptions all say that certain ships have ballistas, catapults or cannons, but the actual units just have one melee_simple attack. Would ships behave properly if I gave them ranged-weapon secondary attack in addition to the melee_simple primary attack appropriate for ship size and presumed marine compliment?

No it's not possible. Naval battle in Medieval 2 is hardcoded.
