Discussions around designing small boats including kayaks and canoes.

Twitchy in chop

I've noticed that kayaks with a box shaped profile at the cockpit
feels twitchy in choppy/confused water.

Question is, if i wanted a design which is better for said condition..then
should i add flare?

I read the ndk explorer feels twitchy in chop..yet it is reknown for secondary stability. Has a box shape profile.
