Peter,
Yeah, that's what I thought, too. So I whipped out my knot stick, which
very accurately measures speed through water, and I pinned the sucker at
the top end of the low range, then tried again in the medium range and
sat around 9 kts.
LIS currents aren't 3 kts, anyhow, and I was going across them, so that
really wouldn't have explained it.
I then raced across the Sound against a heeling 40-45 ft boat and kept
up with them the whole way. When we reached Long Island the captain
called across the water "How the hell did you do that?" "Rhodes-22" I
replied. "Sail them flat."
