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

[bruceyp]

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.

Here is another useful link to have.
Lots of good info can be found here.

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?

My link to Mauri Pro appears to be working fine.
Don't know why one works and one does not, don't forget, I am basicaly computer illiterate.

[sailingdog]

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.

While a bit late for this thread, this might help other people having difficulties trying to link to web pages outside Sailnet.

The problem lies with the fact that Sailnet uses the BASE tag in the HEAD section of its web pages.

The web browser then assumes any link that doesn't start with "http" followed by a colon and two forward slashes is a link to another page on the Sailnet forum site. The web browser then automatically adds the Sailnet forum address to the start of the link address, resulting in a broken link.

Hover your mouse over a few of the links in the earlier messages above and look at what shows up in your status bar and you'll see what I mean.

RULE: Always put "http" followed by a colon and two forward slashes at the start of an external link address.

I've had to use "http followed by a colon and two forward slashes" in place of the correct protocol descriptor as Sailnet won't yet let me post with links. If you don't know what I meant by that, look at the Sailnet web address in the location box at the top of your browser- It starts with "http", followed by a colon and two forward slashes.

Hope this helps someone.

I just finished putting together a page with dimensions and sail area calculations for thousands of boats. Not a unique list but follow the link to a page specific to the boat with sail area calculations in addition to the boat dimensions.
