APRIL 30, 2019: A BLUSTERY NIGHT


 APRIL 30, 2019

A BLUSTERY NIGHT

On approaching the harbor, it was apparent that there was adequate wind for a race. As we left the harbor, we could see that there was a good northwesterly breeze blowing at about 15 knots.  We set the line and called for course W3.  This seemed like a good course for a barbecue night.  We had about 13 boats out for the fun.  We blew a 5 minute horn and set up for our start.

Pair a Dice wanted to start up the line (toward the yellow start mark) and accomplished this with Makani off our starboard hip and Perfect 36 ahead of us off our port bow.  As Makani crept up on us we slowed down a bit which allowed Perfect 36 to be the first to tack over toward the mark.  We all made our way toward wharf with Tusitala first to round and Perfect 36 following right behind them, then Makani, Patricia J, Pair a Dice and Rosie.

On the long run to Blacks there was not a lot of change in order and at the finish it was Perfect 36 (41:36), Tusitala (42:19), Pair a Dice (47:10), Patricia J, with Jason single-handed (48:03), Rosie (53:40) and Aeolian (54:10).  All times are elapsed and the length of the course was 3.23 miles. I know that Makani, Pacific Spirit and Auquavie finished way ahead of us but something happened with their Race QS track so I do not know their times.  Special not should go to Avatar which had an exceptional race coming in between Perfect 36 and Tusitala.  Unfortunately, Their RaceQS track did not show on my track.  We will get to the bottom of the Race QS mystery.

With only “15 knots” of true wind, it sure was a blustery night.

RACE QS:

There were many more boats out tonight, but many did not upload their race QS track.  Unfortunately we can only count you if your track uploads. This is a free app that allows us to track all boats in our race if used correctly.  From my experience there are several things that can cause a Race QS malfunction:  battery running out while recording the track and not having your phone GPS enabled. Also, when I use my phone for Race QS, it is dedicated to this app, I do not take pictures or take calls while the app is running.  On Pair a Dice, we have started using two phones (it is a free app) to record.  If one malfunctions upload the other.  It is still fun to come out and race, but it would be good to see how you are doing, so  it is suggested to record on 2 phones in case one malfunctions.

BLUSTERY WIND:

One of the boats indicated the wind was 15 knots true.  It sure felt like more to me.  I was wondering about the effect of temperature on the effect of wind on sails (this evening was unusually cool).  It made sense to me that cooler temperatures would have more force than warmer temps.  I know we had our 155 jib on this night, but we were heeling a lot!

It has been shown that cooler air IS denser and exerts more pressure on our sails than in warm air. One person even thought there should be a gauge similar to “wind chill factor” used for sailing predictions.  “the wind today will be 20knots but will feel like 22 knots”

DEALING WITH INCREASED WIND:

We all know our boats and our limits with regard to wind.  On Pair A Dice, I have a jiffy reefing system and can put the first reef in within 60 seconds.  Some people will change to a smaller jib.  Some, rather than changing to a smaller jib, will move to the outside track which opens the slot and allows you to keep the larger jib for a little longer.

Once, I was in the Santa Barbara channel in 40 knot winds, going down wind. We had one reef in and no jib.  We determined we needed a second reef in the main.  I gingerly climbed to the cabin top as the sail was lowered, I needed to thread a line through the second reef cringle. In 40 knots this is nearly an impossible task , as the leech of the sail flails wildly.  I ultimately succeeded and we got our second reef in.

 When we returned, I was talking to a dock mate about the experience and his advice was to always have a small line looped between the first reef cringle and the second reef cringle in the leech.  This small line between the cringles should have a loop tied in it, so when the second reef needs to be used, you can put the reefing line through the loop, pull the line through the second reef cringle and tie off the leech part of the sail. Use the Cunningham to keep the luff in place.

Looking forward to next Tuesday.
