Hi,
Funnily enough, while I was building the Orca, my family nicknamed it 'the ugly boat' 'cos it sure aint pretty! But, its function over form, which appeals to me.
I have scratch built many boats of different types, and the Orca was easily the hardest hull to get right due to the curves at the bow.
I am not entirely sure of the Orca designers, but I think it was Damen. The sea axe is a Damen design and is being used for a wide variety of applications, from fast crew launch to superyacht tender.
