A couple of Questions

1. When sailing straight down wind, It is refered to as 0 Degree angle to the wind, correct?

Why is that not 180 degrees to the wind?
If I am close hauled or beating, in my case, I am around 45 degrees to the wind. Give or take.

As I fall off to a beam reach, I am 90 degrees to the wind.

As I continue to fall off on a broad reach, Im around 120 to 140 degrees off the wind.

But when I sail straight down wind I'm at 0. Why is that not 180? I don't get it. I'm so confused. (Just Kidding) ( I get it)

Next question..... (and the more serious question)

2. If I'm sailing a deep reach, my main sail starts to blanket the Genny.
(I don't have a cruising Asymmetrical: Its very high on my priority list)
(And no pole)

The leach of the Genny is the first thing that spills air.
This happened just last weekend. I am on a cruise and I want to sail the shortest distance between point "A" and point "B".

I tried to go Wing on Wing but I was not quite to that point. I was probably around 140 degrees to the wind.

I always thought you were supposed to sheet in the Genny.
I tried to sheet in the Genny so as not to deal with the leech flapping around, but when I did so, I lost a lot of boat speed.

I just let it go, when she was full, all was good. The little bit of blanketing by the main caused some loss of air on the leech, But I just left it alone.

What do you do?

Could the sails maybe becoming a bit stretched and too baggy?

I take it that you don't use a whisker pole for the clew of the genoa. Using a pole would help the genoa keep its shape better when you have it out for sailing downwind. The weight of the pole wil help keep the leech from spilling wind. If you have a leech line on the genoa, that will help too. But it could just be that the sails are old and blown out.

T - You kind of answered your own questions, a pole or a spin. You could alter course, sail at a higher angle and jibe back and forth. Not sure if the extra distance would take longer at the higher speed, but it might be more fun. And of course, more beer always helps.:D

How you describe the relative wind angle doesn't really matter. Personally, if I call close-hauled 45 deg relative, I'd call a dead run 180 too. I wouldn't get too exercised about it.

Okay, the usefulness of a genny on a broad, broad reach or a run (say 150 to 180 relative. It's nearly useless at 160, almost totally blanketed. At 180, it's useful again, now you can wing it out. A spin. pole will help keep it there, so you can still daydream (a little) while steering. But if you want to go fast straight downwind, bite the bullet and get an old-school symmetrical kite.

So let's say your rhumb line course is 150, and no kite on board. What to do?

Just what you suspected...head up to 130-140, where the wind's still coming "across" the boat and your genny will fill, then alternate heading off to 180, where you can sail wing-on-wing. Repeat, then repeat again, as searoom and depth permit.

If you don't like this answer, then get a spinnaker, and steer 160 to the wind all day.

I usually know the answers before I ask, But I wanted confirmation from the gallery.

If you have a fairly beefy rig (as I do) and the seas aren't too bad, what about just dropping the main and running with the genny only? From talking to a few offshore sailors, when on a dead run the ones I spoke with (right or wrong?) like to drop the main and raise two headsails and run wing to wing with them...

If you are talking about sheeting in the genny when it is behind the main and the wind is on your quarter or aft - no you don't want to sheet in your genny. Let it fill. Next time you are doing this, try bringing your boom in to the centreline of the boat to get the main out of the way, then let your genny out until it's flapping and pocketing. Now move your genoa lead car forward a bit - I have no idea what your boat is like so can't say how many stops but you want it forward of where it is when you're beating, but not too far ... better to err aft than forward...

Now start hauling in the genny until it fills nicely and is giving you a decent pull on the course you want to go. If the leech is still fluttering and it bothers you, then play with the leach line - but remember that you're going to have to loosen it when you're on the wind again...unless you're racing it's easier to turn up the stereo ;)

When you have your genny set, let the traveller out a bit and then ease your mainsheet out so that you have a bit of twist/cupping in the main. It will lift the boom up so that the bottom of the genny is not so shortwinded...

If you want to get really chronic about it, you can make a note about what angle the apparent wind is, and then mrk your genny track and your lines with a marker to give yourself a reference... Play with your sheets and your genny car while you watch the log to see exactly what trim works on what point of sail... Enjoy !
