SURPRISING GUST
During the weekend, the news was commenting about the high
winds we were to experience this week.
Predict Wind gave a much more accurate prediction and the wind was
barely noticeable on the Crows Nest flag.
It was time to haul out the 155 jib!
As we were leaving the harbor at about 5:15, it was amazing how much
South was in the wind which was confirmed when we took a reading, it was coming
from 130 degrees at about 5:30 so we set a line square to that direction. As 5:15 approached, the wind was going more
East, but still very light. In an
attempt to be sure all boats could finish in this light wind, I came up with an
impromptu course of Start to Blacks, the pin end of start line and finish at
start mark.
As all 18 boats were setting up for the start in the very
light wind, I was impressed that everyone got a clean start off the line. By the time we got to Blacks, the wind had
increased to the point that the whole race was going to be over in 10 minutes
or less. I announced a lengthening of
the course to go around Gov and finish at the start buoy taking Start to
port. At Blacks, Aquavie was first
followed by Perfect 36, Sweet Pea, Avatar, Pair a dice and Nidaros.
On the run from Blacks to Gov, the question is always:
outside course or inside course? It seems all of the boats went outside except
for Pair A Dice. We wanted to take
advantage of more wind since new easterlies usually build more inside. This required that we sail through some kelp
beds, which can be a dicey proposition.
We rolled the dice and carried on going the inside route. With Stefan at the wheel, I went forward to
guide the path through the kelp. This
was when I noticed a very westerly flowing current that had all of the kelp
flowing away from us, making the path less risky. The westerly current was helping us, almost
like riding a conveyor belt. At Gov,
Pair a Dice was first around followed by Zoop, Perfect 36, Avatar and Aquavie.
Zoop, Guenther and New Wave rounding GOV |
On the beat back to start/finish, we sailed further out to
avoid the adverse (for this point of sail) current toward the beach. We sailed out until we saw the apparent wind
decreasing a little and tacked back inside. At the finish it was Zoop and New
Wave (no Race QS tracks for either), Pair a Dice 54:48, Patricia J 55:39,
Perfect 36 57:00, Avatar 58:03, Nidaros 1:03:01, Aquavie 1:05:39, Sweet Pea
1:07:46 and Sophia 1:19:12. All times
are elapsed and the course distance is 2.80NM.
The surprising gust that appeared as we rounded Blacks stayed long
enough for all boats to finish!
Race QS:
Par for the course, we had 18 boats out tonight and only 8
ran the race QS track. The only way to
be counted in these races is to run this free app on your cell phone. This app
is also a fantastic way to improve your sailing.

THE WEST CURRENT INSIDE:
Using this west flowing current can offer a tremendous
advantage. From my experience, this
current is more predominant when the Easterly wind is blowing. I believe both the Easterly wind and current
are caused by heavier Northwest winds outside.
All of the predictions for high wind were actually true, but it occurred
off shore. This creates the Santa Cruz
Eddy which is the reason the Easterly wind and current happen. You can ascertain which way the current is
flowing by looking at how the kelp is streaming in the water and by looking at
buoys. Any line or kelp that gets hung
up on the buoy will help detect currents and their direction.
HOW TO INCREASE BOAT SPEED:
There are many ways to help increase your boat speed. Many
of these techniques were covered in our Tuesday night sailing seminars last winter.
If your boat is in the water, like mine, one of my favorite ways is to keep the
boat bottom clean. I am not suggesting
to have a diver clean your boat every week!
For less than $20 of material and ½ hour of time, you can build a bottom cleaner that can reach
to the bottom of the keel. These devices
do not work if you have 3 months of reef clinging to your bottom, but if you
have a diver clean your boat, and use the device once a week, you will notice a
vast improvement in boat speed. Using
this device, it takes about 10 minutes to clean one side of the boat. I keep some of these devices (made of PVC pipe,
floating foam and mat) on my boat which is at Q16. Please feel free to copy the design.
See you next Tuesday,

Sailing Pair A Dice
Good observation Barry!
ReplyDeleteWe were on the ebb tide from 1400 to 1830. I have a theory that the combination of a strong westerly during the day, easterly start up in the afternoon, and water flowing out of the harbor and lagoons along our section of the coast all combine to make this westerly flowing current its strongest. Maybe never greater than 1.5 or 2 kts, but still a consideration when the boats are moving slowly towards Gov.
