Talking about youtube-videos. Here is one I found of an Alacrity sailing in 20 knots of wind. It's quite short, but the guy seems to enjoy himself. Looks like he has full genoa and one reef in the main on.
Welcome to the Alacrity blog. The site entails lots of information about this type of sailboat as well as cruise reports and pictures and stories from more than 40 owners from most parts of the world.
Since I moved to the UK in 2010, I had to sell my boat and have since taken up dinghy sailing, now sailing a Topper and a GP 14 in my local sailing club on the river Ouse in York, and occasionally other places. I am, however, keeping this blog and will occasionally update it if I find any abandoned Alacrities during my travels in the country.
