Hi uogeck,

If you have a std performance jib with the cleat, you will have the clew of the jib aprox 100mm above the spinn pole.

what we do is add a 20 mm block the chain plate to where you would usual shackel a typical jib, the use approx 3ft of 5mm dynema or similar to tighten the jib,tye one end on the chain plate through the eye of the jib clew throught the block and throught the cleat on the jib.

you do not need to have the jib to tight, if you tighten it you will spoil the shape, only honk on the jib in 20-25 knots of wind, be gentle with her.

I have charted infussions and some of the guys add a lenght to lower the jib closer to the spin pole.

The top teams and a length to the top of the jib, tie the clew to the bar below the chain plate and above the spin pole and have and adjustable system.

this lowers the sail force and makes for a better sheeting angle.

this boat works on the diamonds you need to adjust them to get all the performance out of her.

good luck!
