Re: Race foil tuning warm vs cold water

But viscosity does as flying grandpa writes. Ask someone at a towing tank for ships why they measure the temperature so accurately. Even if the density doesn't change much, the viscous effects change massively in summer and winter or even morning/afternoon between some test runs and therefore need ...

Re: Race foil tuning warm vs cold water

But viscosity does as flying grandpa writes. Ask someone at a towing tank for ships why they measure the temperature so accurately. Why don't you give me a link to some info instead of asking me to talk to a person I don't know? Where's the evidence that the viscosity change in water temp between 1...

Re: Race foil tuning warm vs cold water

Warm v cold water make a difference. At 4 Celsius water has max density. Also viscosity is almost 2 times higher than at 20C. Both this factors increase substantially dynamic forces ( lift- coused by underpressure) at given speed. Unfortunately, surface tension that counteracts mast ventilation ris...

Re: Race foil tuning warm vs cold water

i have over well 2,000 miles on this foil in this configuration, so if say its not set up right i would not be able to tell. If you've always used it in this configuration how would you know if it had been set up wrong the whole time? But Gunnar's probably right and I'd think it's something else. C...

Re: Ultimate foil for surf skate like quick carves?

Well, most wingers are on boards 10-20x the volume of the kiter's board with all the swing weight that entails. That right there pretty much makes it a different thing altogether, but there is also the big wing in your hand as apposed to a 45cm bar, the soft power of said wing as apposed to the ins...

Re: Ultimate foil for surf skate like quick carves?

As to the winging, I guess you don't really understand what were after. I must not. I have yet to see a winger in person do half as well with twice as much swell. It's definitely a style we are talking about... I would love to know what that style is, because looking at the video posted earlier in ...

Re: Ultimate foil for surf skate like quick carves?

Lol, at the risk of starting an argument, I don't understand why people are so infatuated with trying to find the ultimate way to surf 2-foot wind chop at 10mph. And if you are, that seems like the perfect conditions for a wingfoil. 😂 I'm really not trying to make fun of anyone, everyone is free to ...
