Yes, local conditions here are reported in mph.
Data from the airport (about 3 mi away) showed wind speed of 22, gusting to 28, during the time I was sailing. So I'll knock my claim down from 31.
Sea state was of no use. Normally the wind is W to NNW, with a fetch as long as 4 miles across the lake. You can make a rough wind-speed estimate by the number of whitecaps and size of the rollers. Yesterday the wind was NE, right off the shore. Furthermore, it was gusty and erratic. The water surface never developed waves on our side of the lake; it was more flattened down, as if someone were aiming a hair dryer right at the surface.
I like the idea of the wind gauge on the boat. Now I want one. Also a good GPS. Using the local yacht club's Olympic Circle race course (.5 mi from center to any buoy), you could identify a windward/leeward course and use the instruments to create a cool data table. Well, OK, only if you think data tables are cool. Personally, the prospect of sailing back and forth all day over the same 880 yards, constantly changing sails and entering numbers on a chart, just fills my heart with joy. See, I've already started it.....
