simplified construction?

I am trying to find out wich would be the easyest way of getting myself
a male plug or mold.

Does a ''good'' boat (bayliner-sunseeker model) needs to have concave forms? Or can it be formed out of simplyfied convex forms.

It is rather a strange question... I know

I would like to see if is possible to cut a plug out of foam by only using x/y cutting over a sort of guiding profile, but this is only possible when the plug has no concave forms in it.

I'll try to have some pics of what I mean

I would be extremely hesitant to copy a hullform that is already built. I don't know what the laws are in Europe, but in the United States it is against federal law to copy hullforms (US Boat Hull Design Protection Act, 1998). It is the same as copying a book or a piece of art. You would be infringing on the designer's original design rights. Research the issue thoroughly. Since the Bayliners are built in the US, you could be opening yourself up to a US federal lawsuit.

Oh sorry, I did not put it in the right words.

I wanted to say that I like the Bayliner-Sunseeker models, I don't actually want to copy one but I am willing to redisign my previous design upon one of those types of boats. But with the difference that I would like to get a design with some kind of simplified forms so making a direct 3d cutout would be an easy thing to do.

It still is a strange question I know.

What you are talking about is developable surfaces--surfaces with only one degree of curvature. These include cylindrical and conic shapes, as well as flat panels. It is possible to develop convex sections forward with developable surfaces. If you look in Skene's Elements of Yacht Design, by Francis Kinney, you can see how it is done.
