I just cannot remember the name of the boat but it was built either in New Zealand or Australia back in the 70's and won the nationals back then. It has an 11" keel with the bulb at the bottom and is a canoe stern. Really was a nice sailing boat.
Obviously, when they went to the 800 square inches of sail they had to use a deeper keel to allow for the increased sail area.
The yacht club I belonged to had a bunch of model boats and we raced on Friday nights and had a ball.
Plan on getting mine back in the water next year.
