The fall back angle of the bow is pretty much a direct result of the width of the deck. At the current steep angle the deck narrows very quickly towards the bow. I don't see the advantages of that. No reserved bouyancy at all and most waves will flow over the top splasing against the beam as the bow is not lifted much at all.
Anyway we should decide on the bouyancy distribution in the bow and then the corresponding fall back angle of the bow will simply appear.
