Here's some info about the single-handers from a Class e-mail:
<i>The Single Handers saw a battle between Class Secretary Simon Lovesey and 19 year old Ben Houghton, pushed by other fathers and young adults. With the building breeze on Saturday the single handers enjoyed some very fast three sail reaches, over taking many of the double handers. Ultimately Ben took the Single Handed title from last years winner Simon.</i>
The s/h nationals were held at same time as d/h nationals.
