Genoa tracks

Right now my genoa tracks, both port and starboard, are set at the half way mark. Under what conditions and to what purpose would I move them forward or aft?

Re: Genoa tracks

Different size genoa sails. When you slide the block on the track it changes the angle the line enters the winch.

Re: Genoa tracks

Sail trim - increase/decrease draft, depending on conditions

Re: Genoa tracks

Hey,

If you put up a smaller sail you would move the car forward. If you put up a bigger sail the car would move aft.

Downwind you may want to move the car forward to allow the sail to open more at the bottom. Upwind you want to position the car so the telltails break evenly from top to bottom.

Re: Genoa tracks

Strong - back. If the wind pipes up move the cars back and it flattens and depowers the headsail. Just as the outhaul does on the main.

Re: Genoa tracks

Lead position controls twist. It will not move the draft.

Where the leads should be really depends on your particular sails. A good rule of thumb for upwind trim is to use upper, middle, and lower telltales. with the sail trimmed for close hauled, all 3 sets of telltales should be streaming. Slowly pinch up higher, and all 3 telltales should start to "break" at about the same time. If the top starts to break first, the lead probably needs to go forward a bit.

When you crack off onto a reach, you will probably want to move the car forward to maintain leech tension as the sheet is eased.

When you are starting to get over powered, move the cars aft to open up the leech, (increased twist) to "spill" some power from the upper part of the sail. Combine that with increased sheet tension to flatten the rest of the sail. (Increased twist is also desireable in very light wind conditions.)

Re: Genoa tracks

Shock has your back... spot on.

NORMAL position is it should bisect your genoa (sheeted hard) at a 45 degree angle (this is minimum twist, maximum draw position).

As the winds pipe up you can "depower" by moving the cars back, this allows twist off at the top of the genoa.

Obviously if you change headsails, you have to move the cars forward appropriately (see the bisect comment).

Wow that is real helpful! This is only my second year sailing and my 150% genoa almost always has the leech flaping, so if i move the car forward this should help??

Re: Genoa tracks

Yes, you need an angle ( try 45 degrees ) that will give you more downward pull on the leech. You might also check to see if you have a leech line on your sail. It would be a cord that runs the length of the leech and terminates near the clew on a little clam cleat. You can tighten that a bit ..but not too much, that you curl the leech.

Re: Genoa tracks

Leeech flap can be caused by the sail being out of shape and is not uncommon. You can have the lead in the right position and still get leech flap. Do you have an adjustable leech line? If you do you can try pulling on it. But don't pull on it so much you get a big "cup" at the leech, the infamous "speed cup". You have to strike a balance with flap and sail shape. I'd put up with some flap if the sail shape looked right.

Follow Tom's directions for correctly locating the lead position for your jibs.
