SURPRISE
WIND
Once again, predictions were for
light 1-6 knot winds. Initially it
looked like the predictions were accurate and a windward mark was set halfway
to Mile. As the clock ticked down to the
start, the wind seemed to increase so the course was changed to S5:
start>mile>S/F.
Once again all boats were sailing
in a single fleet of about 12 boats. All
boats got off to a clean start in the 8-10 knot winds. It was a beautiful sunny
day to be sailing and, even though the wind seemed to die a little on the run
back to S/F, all boats finished. Such is
life when you get a surprise wind.

THE ZOOP SCOOP BY PAUL TARA

SLOW HORSES (not a spy novel)
Here’s
a present for the Holidays; a line-up of usual suspects. The data was
gleaned from sailboatdata.com (an
addictive website if there ever was one). I started with the B fleet, but then
just kept adding boats I remembered until I pooped out.
Speed
increases from top down. The year represents the design’s age, not when a
specific boat was built. The “s” number is a theoretical estimate of a boat’s
relative speed based on it’s design characteristics; it sort of tracks the PHRF
rating, but inversely. “S” goes up with speed, whereas PHRF goes down — the
difference being that PHRF is empirical, or based on actual race results.
SA/Displacement is the number to watch; it represents power to weight.
Once it goes above 20, we’re talking about different animals. That’s the
crossover point where design focus shifts from cruising to racing.
Chronologically,
that point corresponds with the 1970s’ spread of the influence of Ultra Light
Displacement Boats. A good comparative example of this is the C&C 35 with
the Santana 35. The C&C is the only boat in our fleet designed in the
1960’s to the Cruising Club of America (CCA) Rule. While still relatively
light, she’s narrower (10.58’), and carries a higher percentage of ballast
lower. The Santana went into production in 1978. Her ton (!) less
displacement and greater beam (11.92’) reflect an increasing reliance on human
ballast as a substitute for keel weight. The problems inherent in this
trend only became apparent a year later, when a fleet of similarly ballasted
yachts encountered disaster in the 1979 Fastnet Race — out of 303 boats, 75 capsized,
5 sank, and 15 sailors died.
If
you’re interested, I heartily recommend John Rousmaniere’s Fastnet,
Force 10, and Desirable and Undesirable Characteristics of Offshore
Yachts by the Technical Committee of the Cruising Club of America.
The “capsize screening number” shown in the last column of the table came
out of the work of that committee. The higher the number, the greater the
risk of capsize in extreme sea states. Over 2 is not considered ideal.
In
summary, the fleet represents quite a cross section of production yacht design
over the past fifty years. Not only does this speak to durability, but also to
the effectiveness of the PHRF rating system. It also shows that there’s no free
lunch. Every design is a compromise. The trick is to find the right
match. Or, hey, you know how they say, “It’s all about money.” New boats
are really expensive — we might just be a bunch of Sailing
Scrooges. Happy Holidays.
Thank you Paul
SEASONS GREETINGS:
We are planning on sailing,
conditions permitting, every Tuesday through the holiday season. Unfortunately the club will not be serving
food until the latter part of January and several Tuesdays will not even be
open. If we want to socialize after the
races, we will need to meet at restaurants.
Johnnies on the East side of the harbor has an excellent “Taco Tuesdays”
that is very reasonably priced. On the
West side of the harbor, there are several excellent restaurants at the Seabright/
Murray Street intersection.
