tell-tales on a radial

Thread starter #1
Any suggestions for where to place the tell-tales on a radial rig? Should they be approximately the same as on a standard rug? (I just purchased a radial sail and lower mast section, but haven't used them yet.)

Thanks.

"Should they be approximately the same as on a standard rug?"

I'm not sure where you would put tell tales on a rug... ;^)

though they definitely would go in about the same place on a standard sail.

Perhaps a standard "rug" suggests a magic carpet ride, on which tell-tales might be useful . . .

Sorry about that. I meant standard "rig."

Is there any reason to think that the air flow over a radial would differ from the air flow over a standard sail?

Thanks, again.

didn't mean to sound so glib
airflow should be about the same.
doa percentage on the full rug & correlate it down to the radial...

easier yet... eyeball it & go sailing.

It doesn't particuarly matter, the airflow changing won't affect where you put them. Make sure you have at least two sets about a foot back from the luff, and a leech tale. I have three leech tales and three sets of two luff tales. when you're doing it, make sure to line the teltales up with the foot, not the luff.

it is actually an old thread but maybe for some of interests. there is a very good articles about fixing the tell-tales:

each of the tales gives you some additonal information about your correct trim. good look and fast sailing

Thanks, Tino, that article has a great discussion of boundary layers and separation bubbles. I never understood that before.
