Title: Spin tack distance for pole end?
Post by: Craig Wilusz on October 27, 2010, 11:27:19 AM
Hello all.  Sailed our new to us Viper opnly twice.  So far the only question we have for setup is how far should the spin tack be from the end of pole at full hoist?  We are looking at some pics and the distance varies form about 4 inches to six inches.  Any ideas? 

Thank you.

class rules state that it must be AT the end of the pole

In the past, I have seen a broad application of "at the end of the pole."  No puns please.

Paul had a mild case of "I've been around since the beginning of the Class" on this one.  Our current rules do not specify how close the tack needs to be to the pole.  It's kind of self-regulating - too far away and you can't heat up well...

Having the tack four inches off the pole seems a bit much.  It may be great for actually sailing vmg down hill but its not going to help when you need to get a quick set at the top mark or need to come in hot at the bottom mark. I try to tie it right on the end of the pole and with a bit of stretch and what not, it will sit about two inches above the pole end. Make sure when you tie it on, you pull the pole out with the "pole out" line.  If you grab the pole and pull it out by hand, the pole will pull out a bit further and your knot will be too far out.

I dont really pay much attention to it.  I guess looking at pictures we usually have ours within 4 inches of the pole tip on average?  I think i usually try to tie it as close as i can but as Matt say's it will stretch out a bit.

So that you dont have to pull the pole out every time and measure it, we put a mark on our tack line.  Depending on who's rigging the kite and how many drinks they have had.. distance probaby ranges from 0 - 6 inches.

Hope your enjoying the new boat.

Tim,
I am making "making" that regatta a priority.  I will see if I'm back from Galveston by then.

David, if you find yourself stuck in Galveston during that time (Nov. 20th and 21st) please give me a shout.   The Texas viper fleet will be in Houston (Galveston Bay) that weekend for another Turkey regatta.   Like to buy you a drink and introduce you to our group.

In technical terms if you want to sail low vmgs to a downwind mark you would have the tack out 3-6" to "rotate the kite". If it gets to planing conditions or where you want to heat up and go fast a lot having the tack tight to the pole is better. When the kite loads up the boat, the pole bends which makes the luff of the spinnaker looser, which can cause the chute to collapse and or just lose power that should be transferred to the boat I.e. Speed.

In simple terms no more than 4-6" max.

I sail with 1-3" of tack and I  smoke downwind.

Justin is notorious for bailing on a race if he's having too much fun on the leeward leg. He just blows by the leeward mark and keeps on going. Kris Overby did that at last years SA regatta in Dago. I said 'where ya goin?' he was planing off the breeze and said 'SAILING' with a huge smile on his face !!

At St Pete one year, in the early days of the class, Kay and I went way beyond the downwind layline riding a full on planing puff. When Stu from Sailing World asked us what we were doing....our reply was "Viper sailors never knowingly let winning get in the way of having fun"
