Operational history

In 1977 it was reported that the designer's personal boat was a Balboa 20, named ''Genesis''. In a 2010 review Steve Henkel wrote, "Lyle Hess’s designs are usually thought to be prettier (or handsomer?) than most, but in this early design it is hard to see a clear distinction from many other trailer-sailers of the era. Worst features: The cast iron swing keel, weighing more than a quarter of the total boat and controlled by a winch in the cabin, is at best a maintenance headache and at worst could cause serious leakage in the hull due to strain."
