Robi,

At Zandvoort the conditions were well suited for testing out t-foil effectiveness. AS Mark P had injured his knee, this only left John Alani to show off how the t-foils could help. I personally noted how much smoother the older Stealth was thru the water upwind compared to the majority - mind you John Alani's boat was one of the heaviest boats too.

I personally did not feel the need for the t-foil off the wind. IF the boat doesn't nose dive - why do you need the t-foil.?

Sure the t-foil has that look that attracts many people, but the items also need to be effective. The F14's that sail here in Adelaide need the t-foil as they have a higher power to weight/waterline ratio's that the F16 and their hull design is very different to the Aussie Blade.

As i said in a previous post, upwind is where they might help the Aussie Blade F16. And given the t-foils are fragile, difficult to make any adjustments, awkward with beach rollers, create difficulty in the surf - I for one will approach them with caution & a last resort.

Wouter - I understand the dollar implications, but the reality is you are generating a lot of hype over t-foils for boats that were not designed for the F16 rule in the first place. Your boat is 20kgs over weight & wrong hydrodynamics for spinnaker sailing.
