than I do, so take a look at the pygmy site.
The key is that hard chines often lead to a flatter bottom on the hull. So this has a definite effect upon handling and upon the profile of the boat (sides tend to be more vertical). Where chines really come into play is when the boat is leaned and the chine acts like a keel, which should impact tracking and stability. How much of the hard chine makes contact with the water (degree of lean, shape of the side of the hull, etc.) affects how the boat responds, so the further one leans, the greater the contact with the water.
As for tracking, chines matter less than the flatter bottom, which has a larger surface area in contact with the water, and whatever keel is built into the design. According to pygmy, the hard chine produces a slower boat due to the flatter bottom (duh), and tracking may be minimally impacted, if at all. As the pygmy site says when comparing their hard and "soft" chine boats, "The cruising speed and stability for all three are approximately the same."
