Trouble making a boat hull (lofting with 3d spline)

Your workflow needs more attention to detail. It isn't appropriate in SW either!
My suggestion to anyone interested in learning this properly is to read through the Autodesk Alias Theory Builders. Boat/Vehicle surfaces usually are built using NURBS surfaces. For best results it helps to have a good understanding of what is going on under the hood of the CAD software. That is where the theory builders can help.
Something I find works very well is to chop up your reference drawing, and overlay the different views on the correct planes.
Do each panel as one operation.
But if you really want to refine your surface, a program like PolyCad (it's free!) will give better results.
I would also redraw using B-spline curves (control point spline) instead of your fit-point splines. And as Peter said, follow the best practices for working with splines.
But as Fusion has limited surface modelling abilities, it might not ultimately give you what you are looking for..
PolyCad will also let you import reference images, as well as refine your surface like the below.
Take less points and tangent curve to bottom line:
Loft the complete hull at once:
Mirror, loft the stern, stitch to solid and shell 2.7 mm.
Then offset 10 mm.
