Moxie turning faster is somewhat by design... which is to say I made certain changes at the bow because one of the canoe books I was reading said the center of lateral area should be behind the center of buoyancy for better handling. Those changes involved increasing the rocker at the bow (basically the first foot or so of Moxie's hull sticks less deeply into the water than most of the keel line.) That means it turns more easily than it would have before the change.
And the design before the change was as close a copy of the Wee Lassie II design (from which Constance was built) as I could manage with the boat design software I was using.
The slightly slower speed, if real, was not intended but may be an unavoidable result of a boat that turns a little more easily. If she turns a fraction more with each paddle stroke, that is energy that does not go into increasing her straight-line speed.
