I sailed as a 'wacker' GRSC, Otis, Kieth Lord era, n the late 70's when it was a four man crew, a couple of regattas at Belmont. Even back then they flew...... Years later went on to do some yatch 'racing' .....ahh? if that's what you call it.
Wow these 16's can fly nowadays. I remember watching them in the 1970's on the Georges river in Sydney with the spinnaker pole attached to the mast and four up!
The sails need keeling. A dagger board on the bow that is 8 at the mast and 24 at the bow make the boat sail. On keel is faster. SS dagger board on the bow. Race this.
