You need quite a lot of travell length on the F16 downhaul. Between 6 knots and 20 knots I pull my mainsail 200 mm downwards. To get such a travell length would require a rather large lever. I know the lever system from the 49-er skiff.

At least that is why I went for the cascaded downhaul

Actually AHPC is now using my system in their new boats.
