As for the torques I agree with gt22, there is a logic that I don't understand, for having already made hulls I advise you to work more on a half hull and make a symmetry afterwards.
+1 also to make the torques coincide with the keel and the deck edge, when there is not a minimum constraint there is necessarily a risk.
For the smoothing function you can also select upside down, i.e. the keel + deck edge and the torques as the guide curve.
Also to see if you can join the front and back ends.
