Head Sail sheeting angle.......

[Sy-Revolution]

....guide line, I'd like to add one to the sail. Marking the luff halfway up and then taking a line from that to the tack gives a sheeting angle guide line, Am I correct?

I think I read it was so in the YM sailpower book, but I left it on the boat, the sail's laid out in the garden.

Or am I wrong?

As a rough guide the sheet should (if continued from the clew at the same angle) would hit the middle of the luff. So yes, I think your about right.

However, when the sail is set it needs adjusting depending on the cut of the sail, if the foot is loose and the leach is tight, bring the jib carr back, if the leach is loose and the foot is tight, move it forwards.

Hope that makes sense?

40% up the luff. Steve Goacher told me that. Perhaps it relates to Sonatas /forums/images/graemlins/grin.gif

Thanks,...........And what if my leech is hooked to windward, do I move the carr forward or back or something else?

If the leech is hooked to windward then it is prob too tight - if the foot is loose then move the carr back. If the foot is right but its still hooked then slacked the leach line on the genoa off.

This is where "tell tales" fitted behind the luff can be very helpful.

Fit them about 6 to 9 inches back from the luff depending on size of sail, 1 at 1/4 1 at 1/2 1 at 3/4 height.

When sailing to windward if you luff up slowly the windward tell tales should all "lift" together, if the upper lifts first there is too much twist so sheet lead should go forward, if the lower first then leech is too tight so move the lead aft.

Naturally the lead may need changing for different points of sailing/wind strength if you want max performance, but this system sets the sail pretty well for windward work in average conditions.

Thanks folks......learnin', learnin', learnin'!

I thought the line of the sheet thro' the clew should hit the luff at right angles not half way up.....

but watch the foot & leech( & tell-tales) and adjust accordingly....

jonny H has it right
