Rig measurements \'I\', \'J\', \'P\' etc etc

Can someone please help me with rig measurements - what distances are defined by 'I','J','P' and 'E' (and any others?). Had it written down somewhere but blowed if I can find it......

Can I add another question, why are they given these letters? Do they stand for anything?

I bookmarked this page which should help a bit. Go back to the home page and you may get the rest of the measurements.

Also found this

Another site where you'll find these is

http://www.ukhalsey.com/LearningCenter/encyclopedia/encyclopedia.asp

Loads of other info there too. I don't think all the abbreviations on Lake Sailor's diagram are standard ones.

Someone asked what they stood for a while back but no answer was offered as far as I remember.

Don't blame me. Not my diagram.
The link shows a better set of dimensions.

You will find the correct and acurate dimensions quoted

Here

They are defined in the rule book.

IOR measurements for 'standard rig', defined as follows:

I = Height of mast above deck
J = Distance from the front of the mast to the base of the forestay
P = Distance from the tack of the mainsail to the top of the headboard
E = Distance from the back of the mast to the clew of the mainsail
