Cool boat!
I've stuffed my much higher bow through 6' waves with no problems, the water runs up the
deck and off the sides. The bow pops up easily, despite the weight of water over it. Your low, open bow will stuff into a much lower wave and fill with 1000+ pounds of water, and not readily pop up for the next wave. Things could go badly from there.
Your open stern will similarly fill with water if you are unable to stay ahead of a following sea. A wave coming down on it can raise the bow and turn you sideways to the waves. It can also flood out those supercharged engines. You certainly have plenty of
power to stay ahead of any wave, but you might not be able to do that. With that bow you won't dare top a wave and dive into the next, you will have to try to stay on top of a wave, and that might be impossible in confused seas without continuous swells to ride.
I'm not sure how sharp a wave you will be able to top without raising those props out of the water and losing both
propulsion and
steering, which will broach you sideways to the waves. A boat with rudders and props under the
hull will do much better than one with props far back like these.
You will have no problem in long swells 6' or more tall, but in building waves or storms with short and confused waves 6' tall, you will be in
danger. If waves are being called with a range up to 6', every 1000th wave can be twice the reported wave height, something to consider.
