My hope is still to get away with the chine runners only. But people who seem to know more about sailing than me (which is basically everyone) regularly suggest I should add something to keep the vessel tracking in a straight line while sailing. Lee boards seem to be the obvious choice.
In my design I’ve added some reinforcements to the hull and something for the boards to pivot on. I’m thinking this could be done even simpler by just using a piece of rope tied to the cabin sides. We’ll see about that when we get there.
The bottom will also have longitudinal runners, also helping to keep the vessel tracking straight.
