Boat hull loft interections

WaldPinkler

This is truly driving me mad. I'm trying to make a solid wall boat hull. Just the stern for the moment. The lofting is driving me nuts.

Here's where I'm at with the model.

I've tried making the loft in multiple directions but keep running into issues with vertices aligning when lofting. I'm trying to make the wall solid, hence the doubled lines. The outer wall is fine but the inner creates problems. Thicken doesn't work because of the hull sheer not creating a horizontal surface.

The offset splines don't line up to use as a guide either. They are the same width but of course the angles change the intersection. The bottom is similar on a zoomed in scale.

@joshua_jenkins063, an easier approach is to just loft a single surface (inner or outer).  Then you can select the hull surface and multiple planes to "Enclose" a volume to convert from surface to solid.

Then shell the solid.  If you make your document public and post the URL you'll likely get better recommendations.

Thanks for that mate, I didn't realizxe I had to change the settings to public.

Hopefully this link works fine.

I've tried enclosing but I can't get the loft and guide right on the inner because of the intersecting position of angles not lining up.

You can actually choose a point as one of your profiles. Here's how I'd do it. I'm lofting the front profile to the prow point, and using other curves as guides. Since I did a solid loft the surrounding faces are already parallel to the cardinal planes, and when I shell, it keeps those faces.
