David Parker had a Sunfish sail already and needed to see if it would fit on the OZ PDR.
The Sunfish is an American class that is very low to the water - one of the original "sailboard" type dinghies (don't confuse it with windsurfers).
So there are none of these sails in Australia.
The sail fits OK without any changes to the hull at all - particularly if you make an OZ type square hollow mast to go in the step.
Full information including mast length and the only drawback is here.

Anyway - this means that a whole bunch more people can use, sail or race PDRacers. Some Sunfish sailors might want to sail something bit dryer during the colder months. Yeah - it won't be quite as fast - but
it still goes upwind fine and you'll be able to step ashore with dry feet.
And it will only cost you a couple of hundred dollars in materials as the PDR is so cheap already and fully detailed plans for the best of the PDRs -
the OZ - is only $20
