So here's a simple question for Neal:

By some miracle you sailed your boat up to New England where we have real fog. You're
crossing Vineyard Sound in a pea soup fog, with a 20 knot SW breeze. I assume you're
carrying full sail, since you've often said that anything less would be unsafe.

You now hear a fog signal close by, roughly off the bow. It is a "prolonged-short-short".
What do you do?
