In the meantime Anna S. from State College had been sailing my Mistral Malibu with my 6.2 m^2 sail*. She found that board pretty long, heavy, and sluggish to turn -- so she was happy to take over my Bic Techno 148 liter board as well as my harness and PFD. She showed, in the following video, that she really knows how to use the gear. She demos a nice waterstart, a pivot jibe, and a nice, stable, one-handed tack -- and she got hooked in and planing a couple of times.
Also shown sailing are Alex and Sveta H., who turned out to be the parents of one of my students from about 7 years ago. They have their own board and sail.
