What are I J P E and what do they mean to me?

I know that these are the dimensions of my sail plan but what do they actually measure? And other than when I am ordering a new sail, when will I use this info? Are these numbers that I should be memorizing? (More likely, saving in my phone).

Aside from when ordering sails, you will usually need to report them if you race and are applying for a rating certificate for your boat. But there's no real need to commit them to memory.

Here's a good link that explains what measurement each letter pertains to:


EDIT: Sorry, but SailNet seems to be having trouble with hyperlinks lately. Try this (you may have to cut and paste in your browser, preceded by www): (secondwindsails.com/measurement.php)

I—distance between top of forestay and the foredeck
J—distance from forestay chainplate to mast
P—distance from boom to top of mast
E—length of boom

Mainsail area is approximately (P * E)/2. This is only approximate, since most main sails are cut with some roach.

Jib area is approximately (I * J)/2. This is also only an approximate because some jibs are cut with a high clew, to help the helmsman see under the sail or other slight modifications.


Here's JRP's Link : LINK

JRP... the forum autolinking keyword software is screwing you up.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

SD,

Looks like you're having the same problem with SailNet hijacking your links. This has been happening quite a bit lately, it seems ever since they increased their hyperlinking in the text of our posts. Very aggravating....

Edit, okay, I see now that you found a way to get around it. How's that done?

It worked because Sailnet doesn't sell SAILBOATS, so the word sailboat isn't getting autolinked.

I usually just type a word I want to use as the link, like LINK, or HERE, and then highlight it and paste the URL into the box that appears when I click on the link icon (globe like thing with two chain links) in the tool bar.
