Oh I see what you are thinking now. I can see how that would make sense in theory. Several reasons why in reality it is not an issue.

1. The traveler only lets you set the boom maybe 20 degrees off the center of the boat.
2. If you are running you will have the boom approaching 70 degrees or more off the center line.
3. Running you will want the main sheet loose to catch some wind
4. Your mostly only concerned about a jibe on a run. Unless you fall asleep at the wheel.
5. I don't think most folks move the traveler to leeward when reaching most of the time. Something about sail shape. Maybe in a stiff breeze to de-power the sail.

Good visualization but the traveler will not help with jibe prevention.

Yeah I get it now. When I said reaching I was actually thinking running. My bad.

Thanks for the help.

Eric

All of the above is wise and proven techniques. However I like a systematic approach. Trim the head sail first (if you have tell-tales it's much easier) then the mainsail using the advice given by the previous posts.

Sail trim

The winds were 2 or 3 knots.

Is this right?

I'm surprised no one mentioned tell-tales: Three evenly spaced on each side of the jib, one each at the ends of the main sail battens.

On the main, if they aren't streaming back, ease out. On the jib, you want the leeward ones streaming; windward too if you can.

Don't have time for a full tutorial, but I'm sure there's one here some place.

In a 15 footer you may have a dagger board (Keel.) If the wind is really light it might help to pull the board up a bit to create less resistance. This would hurt your pointing ability in a fresh wind but it might have some positive effect in light winds.

Main out a bit for light air

I agree with the previous posts but would add that dropping the traveler a bit can open the slot and thereby increase flow over the sails giving you a bit more power. Anything you can do in very light air to increase flow can help including sometimes flattening the sails to keep air flow attached to the sail.

Our Buccaneer18 is naughty that way.

As winds increase, the true wind may outpace boatspeed and seem to come more abeam -- a 'lift', which allows you to point higher. But eventually heeling force overpowers the small boat, you have to crack the sheets, and your pointing ability suffers again. In screaming winds, a beam reach may be the best you can do. Our dinghy points best between roughly 8 and 12 kts TWS.
I just wanted to say this is one of the most useful bits of information I've read yet on sailing a small boat. I've experienced this in my (very) very small boat, and wasn't sure what was going on. As it's a lateen rig most of the trimming advice isn't applicable, but this explains so much.

Thanks!

Bill

Polar Diagrams

I'm not sure if I caught what boat you have, but as most polar diagrams will show, you actually get more speed when you're several degrees off a close hauled setting. So you have to decide what will get you to your destination faster...sailing faster, but further off the wind, which means an additional tack or sailing slower, but closer to the wind.

Very light air

Pal,
In very light air, under 3 kts, you did exactely the right thing. Another knot or so of air and you need to loosen up. Sail magazine published a book years ago that explains the physics of it all, and this is what works. The book will tell you why. Books!

traveller

My 24 C@C didn't come with a traveller. The main sheets attaches tothe cockpit floor with a swivel. I haven't felt it compromises my sail control. Just one less thing to get in the way. Idon't have a boom vang either although I can fabricate one with some equipment Igot with the boat. I guess I just try to finesse the sails the best I can in light air.It isn't my boats strong suit anyway as it seems to sail better over ten knots. There's always upgrades to do and it just depends on the priorities. I just put an autohelm on it this fall and couldn't be more happy with it as a solo feature.
