I = vertical distance headsail shackle at mast top to deck
J = horizontal distance shackle at top of furling drum or shackle at deck for hank on, to front face of mast.
P = vertical distance mainsail head shackle to tack shackle on boom
E = horizontal distance rear face of mast and clew shackle.
Measure several times, confirm with sail maker, you may want to have sail dimensions shorter but not longer than the IPJE dimensions.
Talk by phone or in person with the sail maker before placing the order.
