In last year's C-100, we had almost that for a little bit. After rounding Bloody Point, we got into the lee of a flat island while the wind was still pumping from the East. The wind was still way up while the sea state was better there, but still up as well. Close reach, main only (jib rolled up), double trapped at the back to bows up, still getting fire-hosed. The GPS read max speed for the day was 19.99 knots, and it turned itself off some time during that leg.
