I used to crew on a top J30 and the only time we went over 10 was
on a 25kt day with the chute up.

He had the boat well off the Jersey shore and scored 14 knots in heavy swells a
few years back. He's been racing for 20 years and knows how to make boats do
near-impossible things.
It was gusting to 30 today (according to our meters). I caught a gust to 20
still in the slip.
It doesn't surprise me that you never saw 10+ on a J30....I've seen it many
times downwind, but that was with sailors like myself aboard.
