For shear sailing pleasure nothing tops the Tornado.

But for the compromise/comparison:

downwind: F16 can plane on flat water (singlehanded) vs the T knifieing through the water/waves.
I have not double handed yet. I have not had it in big waves yet.

upwind: F16 with full bows you hear every wave hit the hulls, the T is quieter, wider, graceful and powerful.
Comparing F18 2up vs F16 1up, F16 felt like it floated hitting each small waves vs F18 pounding waves with authority.

The mainsheet was very sensitive, 1 or 2 inches of mainsheet would make the boat to tender in 20 kt.
The OEM downhaul needs some work, I do not think the internal system has enough purchase to easily play it upwind like T.
May get rid of internal system, if I go turtle the mast will fill up with water?

I like the versatility of the boat, where one can both single or doublehand it.

The helm responsiveness (quick & light feel) is about the same, since both are lightweight.

The nice acceleration is about the same. Complexity the same. (MORC experience very helpful for spinnaker)

The fuller hull shape, and light weight is what I noticed the most on the water.

In 20kt the boat was completely manageable(single without kite), which was a relief, as I did not want to go swimming.

I could almost say it feels like a small Tornado that planes downwind (with the right wind angle).

Great wind & waves,
Chris
