when beating in at least 10 knots may be the best time to fiddle with it the first time.
Yeah, 10 kts is excellent for learning/practicing. Too bad we're not seeing it often when we're out there. Ah well, patience, right?
On my boat in those conditions (beating in 10+) I move the traveler to leeward until the main is just getting a slight nudge of backwind from the genny right at the luff (mast side of mainsail) for max speed.
How can you tell the main is getting back-winded? I imagine there's something you see in the sail shape, but what?
your boat will be different, nothing more fun than watching the speed meter (gps, whatever) in a steady wind and tweaking tweaking tweaking to find the sweet spot.
Yeah, if we could only keep the damn knotmeter working. Keeps getting fouled with weeds. Grrr
We do have the GPS, and its SOG, but that's a bit slower to respond than the knotmeter.
Another way to extend traveller adjustment thinking past 'the slot' adjustment is to think of it as a way to control 'helm'. I first figure out the 'slot' placement, but if I start getting more than 5 degrees of helm I move further to windward, if I start running out of track it was time to reef 5 minutes ago..
Okay, now I'm confused
. Prior comments indicated moving the mainsheet traveller to the leeward
side as the air gets heavier, to counteract weather helm. And that made sense, as it would seem to achieve two things: Dump more air out of the leach and move the point the mainsail's pulling on to the leeward side, thus encouraging her to stand up straighter. But you're talking about moving the mainsheet traveller to the windward
side in the same conditions?
