Mosaad, right?
In regards to your latest thread about what your wood should weigh, we talked about the exact same things you are asking now in Nov. on
http://spearfishing.world/.

And reading through that thread I can even see that you know how to define the SG in your CAD. So... I just spent a long time answering things you already know and that I answered a long time ago. Maybe you forgot in your eagerness to start a new build.
Anyways, good luck with the build;-)
Best,
David
