Any tips or just better to hit them forward and let them drive themselves under?

In rough weather, a shot directly under one of the forward cranes is very effective. By hitting there, you crack two compartments and the ship's momentum pushes it into the water.

It's been a long time since I needed more than one torpedo on a merchant of any size in rough weather. They almost always go down if you hit that sweet spot.
