Monty Spindler | Testing - How does it work? | Tech Tack Ep 15

A look into Loftsails approach to sail testing.
Amid numerous attempts to introduce innovative ways of evaluating sail performance, ultimately, taking a sail for a ride remains both the first and the last method.

I like all the tech-talks. Very interesting.

Great Info, thanks for sharing 🤙

The testing on a truck does not work because when windsurfing, there is less wind over the water surface and more higher up. The reason why sails always need some twist. Which is not the case on a truck. So any test result becomes pretty much useless.

[@Loftsails]

That is why these kind of tests were done back in the day:)

@@Loftsails FCS was testing side fins on surfboards in a water flow tunnel. Without taking into account the effect of the board, with the rider on it, to the water flow underneath. Making the whole test useless and even misleading. Similar to the sail on a truck testing. Windsurfing is pretty difficult to mimic in a artificial setting with all the flexing going on. So the only way is practice testing. In flat water you can do this quite OK with 2 equal riders, in wave sailing even that gets difficult.

@@BoukeBecker In the end it's about collecting data and pattern recognition. It is not really an issue of mimicking a windsurfer, but more in line with facilities required + budget constrains as well as overall necessity for such endevarous research. But we do agree with you on the value of practise testing:)
