2D CAD For Ship Design?

[Paul 1959]

Hi
I would like to draft a hard chine vessel hull in 2D. I Have tried 3D modelling but the package I purchased, Delftship Pro is not great at replicating an existing design with accuracy.

I have experience with 2D CAD drawing architectural metalwork and also pencil & paper, ducks & splines drafting of vessel hulls. I would like to combine the two...

In addition to the usual 2D capabilities I need two specific abilities from the software.
1) to be capable of fairing a line
2) to be capable of calculating and exporting the shape of hull panels. Hulls are hard chine with no compound curves.

Can anyone help with this?

Regards
Paul

Hulls are hard chine with no compound curves.

I'm having trouble thinking of a boat that fits that description that I would ever want to use, except a barge or a holiday catamaran on two welded aluminum tubes. Maybe I'm using a different definition of "compound curve" than you are, or applying it in the wrong way, but that seems to describe every other boat hull out there.

Are you only looking for software recommendations, or help in the actual process of drawing?

If it's the former (pun intended) then it's either AutoCAD or a knock-off copy that you can afford.

If it's the latter, I think there are forums on the internet where boat designers get together to discuss, but this isn't it. Consider some of the various racing groups, or hobbyist builders. You actually sound more like a hobbyist than a professional builder (I can't really tell) but either way I think you'd be in your element contacting people with shared interests and learning how they do this.
