Yeah, people keep throwing up Seaquest at me, but it's a show I never watched beyond the first couple of episodes. Trek underwater, with added suck.
I have seen the Seabreacher before on The Gadget Show, looks like a right laugh. I guess any remotely fishy ship now is going to get Seaquest and Seabreacher comparisons, cant be helped. The fact its a sort of scuba yellow/black colour scheme also adds to the effect. If I changed it to another colour it might not be quite so submersible, but I love the look of it in that scheme.
Patrick, I'm guessing it's the sort of hump-back shape and small size that's reminding you of the Skyhawk. It was similarly bulged behind the cockpit.
