Can't loft surfaces, some open, some close. Can't figure out which ones and why.

Can't loft surfaces, some open, some close. Can't figure out which ones and why.

Hello, thanks in advance who anyone who tries to help here, as it is a headache for me. I am trying to design but with so much curve I always find multiple problems. 

I got seven sections paralel to the base of the fin. I can loft by making a solid, but I was trying with surfaces and I got the next warning: "selected loft sections contain a mixture of open and closed profiles. Ensure that selected profiles are either all open, or all closed".

And I have seen that sections 1-4-7 work together, and 2-3-5-6 work together. But I can't find out what I have done differently and also, I do not know which profiles are open or closed as well.

Besides this, I would love to hear any suggestions on how the whole design is thought as I believe it a bit complex. 

Thanks you everyone who tries to help again.

Sometimes (most of times in complex geometry), you cannot do everything just in one tool.
You have to prepare/work the surfaces.
Also your sketches are not the best...

Isso é para produção ou... just for fun?

You re a genious. I have always been trying lofting the wrong way. Using the profiles as sections instead of rails. Thank you very much. Great help!
