Programs to model hydro in?

[Shrimpkin]

You needed to have a transom to seal up the leak points below the waterline so that the hydrostatics could work.

I added a transom and changed the draft in the project settings.

Yeah, I realized this shortly after I posted and fixed it.

I hope this sequence of pictures to help you understand what I mean.

If I am understanding correctly, you want me to break it into layers? I think I can achieve the same thing using crease edges, right?



So what is the overall goal of designing a planing hull and running hydrostatics on it? To see how low it sits in the water? The angle it sits? How much weight it can displace at a given draft?

What all can I do in freeship? Sorry for the vague question but I am just beginning to use freeship and I am just curious what I can expect and what I will be limited to.

I attached the re-worked file with measurements taken from my sketchup design. The front of the hull isn't the exact curved profile of my design but I think it's close enough.

No, I have not managed to explain well. It is not to create several layers. What I have drawn are the various steps of a process performed in one layer:
- Take two lines in space to create the port side surface.
- Take two lines to create the port bottom surface.
- Create symmetrical surfaces of both surfaces.
- Create the transom surface.
- So on with the rest of "accidents" of the hull.
Perhaps, to start practicing, you could use a parallelepiped-shaped hull and work to discover which are the hydrostatic and what it is used. A book on the theory of the ship will be of great help to you.

Do you have any specific books you would recommend?
