Chris Kulkczycki did the Skua and after numerous intermediate models came up with the Yare. He said the problem was the peculiarities or the torturing method. There was no way to guarantee what was on the plans would come out in the boat. The only way to get what you were after was to keep producing modified hulls till you were satisfied.
Here's mine. Still going strong after 10 years or so.

Yes the bow is modified.

: I would presume it was by Dennis Davies and one of the DK series.

: Sea Kayaker magazine did an article by CLC and called it the Skua
: 16 and later the Yare. I did a variant - sea kayak bow, less
: rocker, proper bulkheads etc. and paddled it for the last decade
: as my expedition kayak, obviously with fixed bulkheads which
: helped hold the shape as well as deck beams. A tippy kayak,
: looking like a racing K1 when inverted. Very good for skill -
: your skill level went up or you go down! Fortunately I paddled
: with my partner and her Mac50 has the volume to make up for the
: lack of volume in my Mist. I've since replaced Mist with a
: Mac50L, also narrow and tippy though at 510 mm beam is much more
: stable.

: Though there is a tendency to imitate a submarine. As long as you
: ignore this and wait, patiently, until the bow rises out of a
: swell it has dug itself into, then there's no problem.

: Two sheets of ply and finished with a rudder, 18 kg.

: Mine was 5 metres.

: I used a keyhole cockpit.

: I used proper ply bulkheads, 2 hatches with neoprene hatch covers
: with ply over sheets.

: Increased foredeck curve and quite a bit of aft deck curve for
: volume.
