I am currently doing the hull of a WWII warship for model kit
maker. I have layed out about 50 different contours, but am having
difficulty when it comes to areas that require more than one
surface at the rear of the hull. I can't get the edges to trim
properly, but I think that is because I can't get the surfaces to
be tangent to each other. I have one large surface loft
representing about 80% of the hull, but near the rear the propeller
hub is making me miserable. I am having to add in a ton of
different surfaces and none of them are tangent to each other. If
someone could give me a few pointers as to what I should be doing
instead of what I did, I would really appreciate it.
For the surfaces in the back, I'd use fill and boundary. It looks like you need to look at some other surface models to see how people construct things. It's a very different approach than solid modeling.
I don't want to seem too self serving here, but check out my blog, I've got some examples of surfacing stuff that might give you an idea about how to proceed.

Click on the surfacing category from the drop down at the bottom of the left hand side.
Looks like a great project. I wish I could get involved with some stuff like that.
