What are I J P E and what do they mean to me?
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 ...
Sail Measurement Assistance
Sail Measurement Assistance. Boat: Every boat has maximum sail dimensions that cannot be exceeded. They are defined as I, J, P and E, (also Py and Ey for Ketchs and Yawls). Unless you have existing sails to use as a reference, it is always best to physically measure the boat and not rely totally on manufacturers specifications.

Jun 13, 2002. #2. IJPE. I and J describe your foretriangle:u000bu000b- I is the vertical distance from the highest hoist point of your jib halyard to the boat's sheerline abaft the mast (basically, down to the deck level)u000bu000b- J is the horizontal distance from the front of your mast to the jib tack attachment point.u000bu000bP and E ...
Understanding Sail Dimensions and Sail Area Calculation
Primary dimensions for calculating areas of triangular sails. It's usually calculated as:~. Area = (luff x foot)/1.8, or. Area = (P x E)/1.8, where:~. 'P' is the distance along the aft face of the mast from the top of the boom to the highest point that the mainsail can be hoisted, and. 'E' is the distance along the boom from the aft face of the ...

If you need to know the I J P or E of your yacht or rigging diameter of wires which is useful if you are fitting a furling gear or changing your standing rigging send me an email, I have records of most boats. The following formulas will give you approximately areas for: Mainsail = (P x E) / 2 (add 10% for racing mainsail 155% Genoa = ( ( J x I ...
Sailboat Rig Dimensions
Sailboat Rig Dimensions. I = Height of headstay termination above the sheer line. J = Distance between the headstay termination at the deck and the front of the mast at the sheer line. P = Distance between black bands on the mast, or the maximum luff length of the main. E = Distance between black bands on the boom, or the maximum foot length of ...
I J P E?
J is fron the front of the mast to the forestay attachment. P is from the black band at the the top edge of the boom to the black band just shy of the main hal. If there are no bands, the top of P should be around six inches shy of the top, or halyard shieve. E is from the aft side of the mast to the band on the boom, or if none, pick 3 inches ...
Rig Dimensions
The following rig dimensions designated by " I ", " J ", " P ", and " E " are needed to produce a price quote. They are convenient names to use because they are short and are understood throughout sailmaking…. " P " is the luff length of the main-sail, measured along the aft face of the mast from the top of the boom to the ...
SAIL PLAN DIMENSIONS
Here is how we define them at North Sails. I - Height of Foretriangle. Elevation of Forestay, measured down to elevation of main shrouds at sheer line. J - Base of Foretriangle. Horizontal distance measured from front face of mast at deck to position of headstay at sheer line. P - Mainsail Hoist.
Measuring Sails
Measuring Sails. Using I, P J and E , the sailmaker is able to determine the size of the sails for your boat. Genoa jibs are described as a percentage of the J measurement. A 150% genoa jib has an LPG that is 150% of J. LPG is the measurement from the clew of the sail to a point perpendicular to the luff. To find the sail area you multiply LPG ...
taking own P, E, I, J measurements
Join Date: Jul 2015. Location: Western Long Island Sound. Boat: Custom Goetz/Martin 40. Posts: 13. Re: taking own P, E, I, J measurements. The P and E measurements are maximum dimensions. Sailmakers will make adjustments from these numbers to account for stretch and the cut up and set backs of the attachment points.

A boat with a BN of 1.6 or greater is a boat that will be reefed often in offshore cruising. Derek Harvey, "Multihulls for Cruising and Racing", International Marine, Camden, Maine, 1991, states that a BN of 1 is generally accepted as the dividing line between so-called slow and fast multihulls.
Calculating your sail areas
SHW - Spinnaker Half Width (distance from mid-point SLU to mid-point SLE) SF - Spinnaker Foot. Basic Sail Area calculations. Mainsail: P x E / 2 (no roach) P x E x 0.585 (with roach) Mizzen: Py x Ey / 2 (no roach) Py x Ey x 0.585 (with roa.

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize. Formula. 18.75. <40: less stiff, less powerful.
