Hello Ryan,

I haven't been here for ages! I'm back again on this forum after few months of being abroad ( I work as a engineer in power sector ).

I do hope You're ok, aren't you?

Listen Ryan, I got no much time today, but for your information: I've been building deep vee monos using playwood, balsa. When I was younger I was involved in building ABS boats ( Graupner, Kyosho, Robbe ), you know all that plastic boats you could have bought in local store.

Starting 2007, me and my friends tried to organise some kind of a modeller team located close to the big pond in my area. Then we started discussion about hulls, motors, props etc. That's why I'm looking for some kind of CAD program for describing what happens to the boat not olny when it runs, but also when we change it's characteristic by changing the shape, motor position etc. I call it a dynamic analysis of the hull. Why to build a prototype and waste money and time when you can try to do it using a computer? No no no, I'm not against making prototypes at all, no! But some times it's easier to do it without changing the boat using " saw and glue".

That was the core of my question.

Thank you Ryan for your post!
