I used Curve through points when it was necessary, always when I wanted a direct connection.
You are right, I failed with the transom. Right now I’m dividing it like this:
How to surface the transom separately? And how to glue them together, without losing the exactness of the boat plans? It gets so easily distorted using loft.
I discovered the reason the hull surface was not aligned with my curves was because of the “loose” style when I lofted, I changed to “Tight” and it was better. Still distorted though.
