Not fully powered on the 6.4 but managed one or two runs where everything was starting to feel right - just a few more knots of wind would have seen a few more knots vmax.

At this lower end the Drake 32 runs about 0.6 knots slower than Tectonics 30 but has much better upwind performance.

But with the Tectonics you're just waiting for that extra squall when you know it won't hold you back.
