============= Tue 4 Aug 97 - 3rd - 5.4,4.9/257 (187#)
Conditions didn't look all that promising, and Monday was 6.0, but I
wanted to catch another day of the ebb. I should have known: Michael
left for vacation Tues morning, so I guess we have him to thank for a
GREAT day!
I rigged my usual 5.4/257 ("Goofy") and was powered off the launch
at 3:40. Great ramps inside near the channel at first, and then
the swell started building in the channel as the ebb started.
Around 4:30 I came in to rig down to 4.9 ("Mickey"). When I went back
out I was way powered! Ramps were really great and many sailors were
hitting 6' jumps. Swell got to around 4-5', some nicely formed for
jibing. The wind continued to ramp up all afternoon. I never sheeted
the 4.9 in after about 6:00, so I could have been on a 4.0. The water
also got choppy later on, and I quit at 6:40.
Despite weak-looking pressure gradients as late as 2:00, the fog came
sailing down the coast and gave us a great blow. NWS and COTW (and I)
missed it entirely.
The parking lot was pretty empty when I arrived at 3:00, probably
because pager reports didn't start coming up until 3:00. The only
instrument reading even close to the conditions in the channel was SoSF
(San Bruno Mtn). This showed 21 knots at 2:00, ramping to 29 knots at
5:00 and holding there. SFO showed only 20-23 knots from 2:00 to 6:00.
Coyote(COTW) showed 13 knots ramping to 22 at 5:00 and then falling (as
the fog front blew past Coyote). And 3rd(COTW) showed a piddling 11
knots ramping to 13 by 6:00. This would indicate a light slogging
conditions at the launch, but that was not the case. I sure wish we had
an instrument in the channel!
I don't expect a repeat today, but it should be good sailing.
Key to Jay's new sail size convention (taken from a line of kid's sails):
Goofy is your standard sail size for a good day at 3rd (20 knots/23
mph in the channel). For me, this is 5.4/247 (188#). For Michael
at 150#, this is 4.9/8'6.
Scrooge - two sizes larger than Goofy 7.0 6.0
Donald - one size larger than Goofy 6.0 5.4
Goofy - std 5.4 4.9
Mickey - one size smaller than Goofy 4.7 4.3
Minnie - two sizes smaller than Goofy 4.2 3.9
