chine height at the bow

i will try on my model to rise a litle bit, 10 minutes with angle grinder, i have enough fiberglas thickness

 

What do you intend to improve by raising or lowering the chine? Not everything depends on the height, you also have to take into account the width, the angle of entry, the size of the waves, ... there are many variables and it all depends on what you want to achieve.
Do you want to follow current trends for bow shapes?......

 

I want to folow the plumb bow shapes only for estatic reason, and get the best performane on seakeeping as i can from plump bow.
Even if i know that is not the best design, ( i meen plum bow design)
I want to balance to keep the boat broach free as i can, and to not have to much slaming going in head sea.
I think resistence from monohedron 15 degres it is what it is, so this part i think is ok, i think will be like on maxsurf prediction 25kts 50liter per hour at 6700-7000kg load
Max speed 36 to 38kts

 

Stick a spray knocker on your model above the chine, and see what difference that makes
