Hard chines and tracking

I've read several threads here about hard chines, tracking and stability issues, but they never seemed to reach any concensus.
Primary and secondary stability aside, with all things being "equal" do hard chines equal looser boat in flat(ish) water? Or that is boat-dependent? Reason for asking, I've tried several boats over the weekend and all hard-chined ones (I never paddled one) - Arrow Play LV, North Shore Buccaneer and Tahe Greenland LC (Tahe less so due to smaller volume) felt very loose in the bow. The maneuverability felt really good, hard chined boats seem to turn on the dime. But tracking? Are they supposed to be so "loose" without skeg deployed? I liked the feeling of hard chine, but the tracking issue was a bit off-putting. Running skeg in flat water seemed odd.

This hard-chined, tumblehome-flat|

sided whitewater boat tracks very well, once it gets moving, but once you lean in or out to change course, those chines may leave you tipped up and over.
I'm thinking of the Silhouette|

chines and tracking|

In my experience, tracking is mostly defined by the rocker. Keep in mind - rocker might change depending on load - same kayak will track differently depending on paddler's weight.

In moving water and white water, a boat with harder chines and flatter bottom will feel loose on the water compared to a boat with similar displacement and other parameters. And I'm not talking strictly whitewater boats. For instance, the P&H Delphin is flat bottomed and rather hard chined and sharp edges in the front and rear, with hard chine with rounded edge near the seat (kind of opposite to other hard chined sea a kayaks, which seem to have sharp edge near the cockpit and soft edge fore and aft). That boat, as long as you do not edge it, is very unaffected by cross currents, compared to a rounded bottom with a V like the Zephyr. The Delphin will go where you want during eddy out maneuvers where you don't edge it, while the Zephyr will be swept downstream. The current just slides under that flat bottom. But if you want your edge to grab and for you to peel out and turn downriver, edge it and it will do what the Zephyr does.
Opinions about round hulls and hard |

chine hulls will never give a reasonable answer. Other hull design features play a much greater part in tracking and maneuverability. The part of the hull that's under the waterline will tell you a lot. A hard chined hull can make carving turns better and it can also reduce side slip when paddling with a side wind. Besides that there really isn't much difference.
All boat design is trade offs|

One design element called "chines"|

doesn't define handling characteristics. Unfortunately a lot of advertising copy lends one to think it's a defining characteristic when it might simply be an artifact of a construction technique.

Given two very similar boats the one with hard chines will handle differently
I own a North Shore Buccaneer|

than I do, so take a look at the pygmy site.

When I visit my brother I often use his second boat which is a Cape Charles 17 (Chesapeake Light Craft). Basically an unsophisticated 24" wide hard chine wooden tank. I always enjoy myself in it, and have been in all kinds of conditions and mild surf. I think with a lot of kayaks the basic principals far outweigh the differences and allow you to enjoy a lot of variations in crafts. As long as it's not a severe weather cocking boat and the seat is comfortable, I can have a good time. What's amazing is in groups with other kayakers with longer, faster boats, I can easily keep up without killing myself and I don't consider myself excessively strong or fast.
