Air density is higher on the coast so 25-30 will feel different than 25-30 at 3rd

They're talking about the channel sensor - normally the wind closer to shore will be significantly lower.sc-surfer wrote:You guys are madmen! At 25-30 I'm feeling the juice on my 7m.
A kite size lower maybe? My experience is pretty consistent with Marinkiter - if the channel is 25 with gusts to 30, then I would downsize from 12m to 9m. That's at 190lbs on a twintip.

Re: 3rd ave wind meter wrong
Yeah, I keep hearing this air density <=> temperature <=> power correlation too, sounds dubious. I'm sure there's a difference, I just can't imagine that it's very noticeable @ 25knots between 80 degree vs. 60 degree weather.
Any Bill Nye's wanna prove me wrong?

Over a range of 60 degrees C (or 108 degrees F) there is only a 24% change in the density of dry air. So the 20 degree F change you refer to would imply about a 4% change in air density.
Negligible.

Re: 3rd ave wind meter wrong
I must say that cold air always feels more punchy to me. But maybe it's because it happens at the coast and I think about GW. :mrgreen:

Re: 3rd ave wind meter wrong
The gust sensor at 3rd is actually the avg wind speed. Average it with the channel sensor.

That sounds like a good advice Keith.keithdkd wrote:The gust sensor at 3rd is actually the avg wind speed. Average it with the channel sensor.
I usually rig one size up from what the channel is blowing since I stay around the lower launch.
