Fun times pushin on the F4 at Kurnell, all alone except for a few wind wings, kites and sunbakers.
I could have used a 5.5 in the big gusts and a 10 in the lulls.
5-6 felt more controlled... perhaps with shim, perhaps cause the wind dropped a touch and I could really push.
Top speed was heading towards the beach, in flat water, and a gust. 9 runs touching 25 kts, but pretty sure a fin would be doing about 32-35 depending who was on it. Alpha getting closer to 20kts but inefficient shape for my best gybe. Good day.
