Seriously you cut it up?

I never had one out in substantial waves. What struck me about the Kulzychi designed double is that it was simply a scaled up Chesapeake 17. The Ch 17 was a high volume kayak and the Ch Tandem was very high volume. The Chesapeakes were an evolution from the highly rockered low volume end Cape Charles and Patuxents that would bow bury in 12" waves. The Patuxent 17 I made in '94 buried to the coaming in 18" waves.
The Chesapeakes addressed the weather cocking of the Cape Charles but above 10mph or so breeze leaning became less effective. The issue of bow burying was partially addressed
by moving the cockpit back and increasing the entire volume of the hull with high freeboard. But the bows were not high volume at all because the construction technique of a pre-glued sheer clamp prevents the side panels from flaring.
I had built a Chesapeake 16,18,Northbay,Pygmy13, PygmyCoho then an Eric Schade Shearwater 16 and 18. The Shearwaters were four panel hulls but without pre-glued sheerclamps. They looked like med/low volume hulls that would bury easier than the other boats but when I took it into the surf it was great.
Thereafter I built a heavily modified version of the Northbay and discovered how the pre-glued sheer clamps prevented the side panels from flaring while forcing the center panels into a sharp v, which ensures then ends will be low volume WHEN mated to that one piece deck that can't tolerate an upswept shear.
