Re: Wind Direction Question from Noob...

The wind can can shift directions. There may be prevalent direction. However daytime heating of the ground as well as obstructions can cause that direction to shift.

Being new, the trick is to keep the sails trimmed to the correct wind direction and speed. Easier said then done! Because you are sailing a dinghy there are a couple things you can do to help yourself out. First, put tell tales on the sails. Your job is to keep those telltales streaming smoothy. Second put an official wind direction indicator on the shrouds. You can use a yarn or ribbon. Six inches long. Just tie it on at just above head level. MY favorite official wind indicator for noobs is cassette tape. Pick an old favorite and cut it up! tie it to the shrouds. Cheap and effective!

Re: Wind Direction Question from Noob...

So after a great 16-day vacation to the States, I came back home to Abu Dhabi and spent 2.5 beautiful hours on the water today. Thanks to my jet lag, I was finally gave up trying to sleep around 4:00 in the morning and decided to head out for some sailing. The water was beautiful at 7:00, but much calmer. I have 2 more questions:

1. Why is the wind much calmer in the morning than any other time of the day?
2. It seemed to me that fastest I was moving was when I was in a beam reach. Is that typical for sailing? I assumed that a run would be fastest since the wind is pushing you from behind. So in order to go as fast as I can, should I always try for a beam reach?

I'll ask for some advice on my tacking in a later post...

Thanks,
Mike

Re: Wind Direction Question from Noob...

Mike,

The wind has a lot to do with the heating of the earth and when the hottest times of the day occur, with pressure, with density, etc. It changes depending on the season, too. Of course it will be different where you are, in the summer where I am we *generally* see the wind decrease in late afternoon and early morning has the best wind. Plenty of times we've woken to terrific sailing wind, dawdled over coffee and an hour after we left the marina: gone. Although, depending on if a front or squall is coming through, that may change day to day.

The most efficient point of sail is a beam reach.

Re: Wind Direction Question from Noob...

As I understand it, the beam reach is more efficient because of the aerodynamic effects of the wind over the sails. You actually get more "force" out of the wind because it doesn't just hit the sail and eddy off, it is allowed to flow through the sails and generate lift (or some approximation thereof).

Re: Wind Direction Question from Noob...

Ok, next question...

It was a beautiful day today, so I went out for a spell. I was out for almost 2.5 glorious hours. The gusts were out of the south at around 17 knots, so I was cooking in my 16foot dinghy. When I was sailing on a beam reach with the wind coming over my port side, I had to let go of the tiller extension because of the tension and hold the tiller at the transom. However, on my way back, with the wind coming over my starboard...roughly the same speed and direction, I was able to use the tiller extension. My question: why was I fighting the tiller in one direction and not the other when all things are equal?

Make sense?

Re: Wind Direction Question from Noob...

Lucky you, sounds great! I was out this morning in a 16-foot dinghy and I had just barely enough wind to keep the sails full. I alternated sailing and drifting.

Anyway, on this little lake it's not uncommon to pick up some seaweed. If it's dragging off one side of the centerboard or rudder it can cause asymmetric behavior like what you described.

Re: Wind Direction Question from Noob...

I wish I could say it was seaweed, but here in Abu Dhabi there just isn't much around...

It was an awesome day...I wish I could have stayed out longer but it was almost 100 degrees when I got back to the dock around noon. Thankfully it is actually starting to cool down, so I will be out longer all winter long. How is the weather in your neck of the woods?

Re: Wind Direction Question from Noob...

Rigging that isn't properly tensioned will cause that to happen. Or, it's possible that your guestimate of the wind speed on the opposite tack was incorrect.

Hah! I hadn't noticed your location.

Again, lucky you, sailing all winter! We just got off a sticky stretch of mid-90s and humid, now we're easing into autumn and enjoying moderate days in the 70s. Soon the leaves will start to change, and sadly in about three weeks we have to pull the boats for the winter.


I like what Donna said. Uneven rigging tension, or a mis-read or change of the wind.

Re: Wind Direction Question from Noob...

Donna, could you elaborate a bit more about the tension of the rigging? I am only using the mainsail, so what part(s) do I need to check?
