hull design angle

Hello everyone, I participated in some kind of unmanned marine vehicle competition. I have a team of aerospace engineers. In general, we lack information on ships. I was able to find a few formulas and proceeded to the drawing process. While drawing the hull, I realized something and I can't solve it. This is about how to calculate the slope at the ends of the hull, I want my ship to have good stability in terms of stability and I want it to move at medium speeds. As I said, we have a few problems in slope calculations, so I thought I would write directly to this forum without putting myself in too much trouble in terms of design. I have values such as Loa, Beam, Boa draught and depth. My only request from you is to help me with the slope calculation, and also when I start drawing after calculating the slope, I don't know from which length to start from the flat part of the hull under the water. Our Loa is 0.92 and our lower hull will be 0.92 with the slope, but I don't know from which length to start the slope. I would be very grateful if you can help with this issue.

 

It depends on the rest of the design. From what you are asking it seems that you are looking at elements on their own. Desing should be global. That means to take into consideration the interactions between all the elements.

 

My hull design will be like this. But ı don't know how can ı draw this pruva angle ?
