Just to let you know I finally managed to make used of the flat hull design of the S2 27 by surfing downwind on 4 foot waves on lake Champlain, NY last weekend. It was a solo outing and I only had my 135% genoa fully unfurled with gusty winds ranging from 15 and 25+ knots. I did record a few strong gusts exceeding 35 knots.
Here's a short video of what I could read on my instruments then:
As far as I can say, there was no apparent signs of stress on the boat, even if I averaged above 7 knots in the four hour I was sailing that day. Just can't wait to repeat this experience with a spinnaker.
