Hi,
does anyone have experience with a WASZP T-foil rudder mounted on a National 12?

When I bought Bouncer from Si Payne, she came with a Mach 2 moth rudder. It did provide some lift but the chord length of the foil was so short it was virtually impossible to steer at low-medium speeds, and the adjustment system (using old shimano gear levers) mounted on the end of the tiller was very impractical. The boat ultimately went much faster with a conventional foil.

Agreed, I have a foil with a pretty standard wing set up on a vertical which is tiny.  I could not steer on start lines at low speed.  But it was very fast once everyone had gone and I had a little bit of space.  I went back to plan A
