Why AP for the water line? If you hit the hull at the water line the hole will be more than enough to cause flooding. Now if you want to hit below the water line, use AP, it would hoepfully have the energy to power through the water and still penetrate the hull I guess. But consider this, Ap is a pure kinetic round, once the round hits the water it experiences a density of 1000 times greater than teh air it was going through. Im not a physicists, but since drag is exponentinal, I believe the square of the velocity or something, your available kinetic energy goes down significantly. So your handicapping the only thing that round has going for it. The lower you try and hit the hull the worse it'll be since it will have more water to pass through. use HE at the water line and the explosion will tear a hole below the waterline and above leaving a bigger hole to flood as the ship beigns to sink and list.
