I don't know if you guys were aware but Navatek makes a line of complex deep vee hull designs, including Sea Blade fishing models 16',17',19' and 22' in fiberglass and aluminum. And up to 30' for commercial users and even larger for the military.
Very interesting hull designs and I can see some comparable ideas on this 25' SeaCraft. Amas, air entrapment tunnels, fine bow, high deadrise, multiple longitudinal and transverse steps, multiple panel running bottom.
30 patents.
Lots of similiarities to the VDH hull.
Read some good reviews of the hull's running ability in rough water; only the layouts aren't that good for fishing.
