Hello Yann,
your design looks beautiful as well!
The plans of the "Nightmare Mk. VII" have been sent to you, as well as to several other interested persons.
As it is a proofen design, you can use it at least to compare it with your own ideas.
You must be ranging at plan No.30, if I didn´t count wrong.

Addition:

Hello Yann,
as you requested per email, here are some more datas:
The overall ready to sail weight of the "Nightmare Mk.VII"-Prototype is 2800gr.
Floats are 380gr. each, maihull was around 800gr. without rc-set or armwinch (HITEC).
As I didn´t complete the boat myself - which was done by the owner Eric Gielen, together with Karl Schmidt -
who is the President of the Austrian NAVIGA-Rc-Sailing-Assoziation -
they added some components which made the boat heavier than I planned.
It was designed for 3000gr. ready-to-sail-weight,
but could have been at 2600gr. if they had done it like I suggested to them.

Anyway - the floats have an overall volume of 7500 cm2 -
which is the proper relation of 250-300% of the overall boatweight!
