There was a discussion on Spin luff tension in 2003 - I was wondering if we could get a more up-to-date comment from the forum on this subject.

My question centers around mask rake, as the mast is raked back or forward the halyard lead stopper on the spin would necessarily need to be lengthened or shortened to compenstate for the movement in the mast.

Also releasing the tack versus the head of the spin in Light air and Heavy?

Some have suggested releasing the tack - but I have had advice that the head should be released - Never the tack.

I release the tack in order to avoid nasty swinging forth and back up there. I have been told from a sailmaker that the higher you want to drive, the tighter the luff. But It would be nice to have some confirmations about this :wink:

It is the opposite of what you said. The tighter the luff, the deeper you'll be able to point. If you want to head up (more of a reach), you'll need to loosen the spin luff. If you are reaching, I recommend loosening the halyard some, as it will drop the sail slightly and give you a better sheeting angle on the spinnaker for that point of sail.

I am also looking for the latest in spin tuning. Has anyone found a good website explaining cat spin tuning? How about a recent article?

Word on the beach is that there's a Tiger crew in your area that has the skills to train anyone.
Her name is Ingrid Gutzmann I beleive
Rumor has it she taught a monkey how to sail the Tiger last year. She had only to repeat the command, "Sail Deeper, Sail Deeper". :lol:

Not sure what a "twings" is. Its in the article.

Very interesting comments on Tack Lines and twisting the spin up and to windward when really running deep.

So here we have the contradiction- Trey Bown says loosen the luff to go high and tighten to go low and these sailmakes say tighen the luff to go high and loosen to point low. Guess I'll leave it half tightened - just in case :wink:

Can someone sort this out? At least the Tornadoes go high and run the luff very tight.

I got my info personally from Mischa Heemskerk during both 2007 Tybee 500 and 2007 Round Texel in Holland. I've also spent time training with Robbie Daniel, who also advocates the same spin luff info.

Thanks James - big boats for big boys - is that correct?

Weekend of high power sailing:

Sat: 20 - 25 knts - New jib and spin - very fast - kept up with a very competitive Nacra F18, have raced these guys 9 times now.

Sun: Very nice 10 - 12knts - fantastic day - duelling with the Nacra, and another tiger - 9 x 5.8 Nacra - Boat was very fast - could make up 10 - 15 boat lengths downwind on the Nacra. And held them up wind.

We raced to the leeward mark - one hull up and flying for over 1 kilometer, side by side.

Only sloppy leeward mark roundings cost a few boats lenghths and Nacra 5.8s (coming in on Port) trying to punch holes in our Tiger kept us behind.

by dropping the halyard a bit for the better angle...about how much do you drop it?

Only a few inches at most (4-5 tops). It will become much more "finicky" and harder to run though at high angles. You will have to sheet it like a mofo.
In the 2007 Tybee 500, we had about a 55 mile tight spin reach and by the end, my crew's hands were about to fold. We switched out for about 20 miles. Tight spin reaching is rough on your sail and your crew.
