According to Matt, Mariner kayaks turn by being edged alone. No initiation required. Something about the asymmetric shape of the hull. Tilt right and the hull turns left and visa versa. Most boats I have paddled are more or less neutral when edged and need some sort of persuasion or initiation to turn. Once initiated the hull will build up spin momentum as the water pressure balance changes. Tilt the hull either to the outside or the inside of the turn and it will carve and turn faster. We call it YAWHOO, but that's another story altogether. I would think that a neutral hull would be better, so when doing a peel out into current, a downstream tilt would allow the hull to freely turn downstream, instead of trying to turn the hull up against the current. Just an observation.
