Re: DIY and heavier air techniques

yes charles - agree - my calculation 14+7 would be for close hauled.? when Bob thought you were doing 21 apparent I didn't think that was the case because you were sailing beam/broad based upon wind meter and how your flag was flying - thus true wind would be close to 20.??

Yes, the boat is a Canadian register vessel, and I live in Canada. But I sail on beautiful lake Champlain where, two years ago, I happen to come across another S2 27 (based in Shelburn bay near Burlington VT).
Indeed we were sailing on beam/broad reach at the time the video was taken. Also, the friend at the helm was inexperience with sailing.
The apparent wind, which is the reading displayed on the center dial in a small window was between 20 and 24 knots. Real wind was somewhat less, probably in the realm of 18 to 22 knots. Your calculation would be more accurate for close hauled.
If you're good in math, you can figure-it out precisely by using these formulas:
