The STOCK Y gun is broken. The only reason the subchaser seems to fire on both sides is that one Y gun point left, the other points right.
Actually, DCs have no collision node, so they ignore hull anyway. You can place them inside the superstructure, they'll still shoot.
The simple work around is to alternate them, but it means that you can never have a single Y thrower on a ship, always 2, one shooting to port, the other to starboard.
