Adding beam at the waterline will slow the boat somewhat, but there are many
other factors influencing speed, not just width.
Adding flare above the waterline will have no affect on waterline width, so
no effect upon speed.
Dories have very narrow bottoms for their overall shape. The center of
gravity is also usually very high, untill the ballast or cargo is added to
compensate.

would initially stabilize (and slow) the boat while widening the gunwales
would add reserve stability. ... Dories are very tender too until they
either have ballast in them (originally fish) or they drop onto their sides.
... As I have tried to draw to your plan the largest cross section of a
kayak, it does get rather "V'ed." I suppose yours is too. Right? Hmmmmm.
of course I was drawing mine wider than you (24").

on Paddlewise? Matt Broze (Mariner Kayaks) and John Winters (Redwing
Designs) weighed in very interestingly, as did a number of others who
obviously had the knowledge and experience to amke the time they spent on
the debate very much worth while.
