Ricky Blender- I do not agree but then again- everybody has his own set of tools and his own methods. I am far from trying to convince anybody mine is the bestest (in fact yours might be excellent) - it is just the one I am using, so I am showing it
So- I have re- watched drawings and problem with bow section profiles is caused by wrong marking. Moving them back solves the problem. Having said that- time to take care of stern section. First step is exactly the same as in case of bow- moving vertices horizontally, in single axes, to get right profile:
So- result should be something like that: a boat- like shape, with sharp bow and stern. Now- any ship built after 1600 will surely have such a bottom, but it will also have a flat stern gallery. This one is on exception- so it is time to work on that one as well…
to solve that problem I am moving my model to lower section of draft, where stern is clearly drawn and- again- I move vertices of last cross- section horizontally. You can observe few things. First? This plan is not an excellent one (although pretty decent, considering age). Second: I moved one vertex vertically (one where stern beam reaches face of stern gallery). Third: to make cross section correct we will need few more loops.
