Simple have a look at the Hobie Wildcat and you see an A-cat type of nose.
I don't know Hans, they sure do look different to me.
And I'm not only refering to the spray rails. That bow height on the Geltek flyer 2 looks to be 250 mm at max. I'll be very surprised if the Wildcat F18 has less then double that.
Summarizing, same hull length double the bow height, no angled down deck and a spray rail.
