sailboat rig dimensions The following formulas are approximate
Sail areas depend on lots of factors, leach hollow, foot round, luff hollow etc. Also, remember that jib sail area in general is based on the forestay length, I. But all things considered, these numbers are close but should not be considered exact. They are rules of thumb, not measurements of a this specific boat.

Mainsail

Mainsail = (P x E) / 2 = 183 sq ft
Racing Mainsail (add 10%) = 201 sq ft

Genoa

155% Genoa = (( J x I ) / 2) x 1.65 = 205 sq ft
135% Genoa = (( J x I ) / 2) x 1.44 = 179 sq ft

Jib

  _______
LP of full fore triangle = ( I x J ) / √  I2 + J2 = 8.2
Jib size to fill fore triangle = 96%
100% Jib = ( I x J ) / 2 = 125 sq ft

A more accurate LP calculator is HERE

Spinnaker

Spinnaker Area = Max Luff x Max Girth x ( 70-85%) = 404 to 490 sq ft
"Square" Spinnaker Area = Max Luff x Max Girth) = 577 sq ft
AC Area = 481 sq ft
Maximum Luff (.95 * sqrt (JSP^2 + ISP^2) = 29.67 feet
Maximum Girth = 1.8 * JSP = 19.44 feet

DEFINITIONS

"P" is the luff length of the mainsail, measured along the aft face of the mast from the top of the boom to the highest point that the mainsail can be hoisted or black band.

"E" is the foot length of the mainsail, measured along the boom from the aft face of the mast to the outermost point on the boom to which the main can be pulled or to the black band.

"I" is measured along the front of mast from the genoa halyard to the main deck. The main deck is where the deck would be if there were no deckhouse.

"J" is the base of the foretriangle measured along the deck from the headstay pin to the front of the mast.

"JSP" is the length of the spinnaker pole or the distance from the forward end of the bowsprit (fully extended) to the front face of the mast.

"ISP" is measured from the highest spinnaker halyard to the deck.

"PY" and "EY" are, respectively the luff length and foot length of the mizzen of a yawl or ketch measured in the same way as for the mainsail.

"IY" is the measurement from the staysail halyard to the deck.

"JY" is the measurement from the staysail stay to the front face of the mast.

"LP" is the shortest distance between the clew and the luff of the genoa.


Data*

This data is supplied as a reference and all boat dimensions should be verified before using it in any critical application.
The information in these data bases is a starting point. There are errors as you can see as the different data bases do not always agree. In addition, some boats have been modified from stock and will not match the data in these databases. None of this data has been checked by L-36.com so please always check your boat before relying on this data.
Data is from a variety of sources.

db = PHRF is the "PHRF Critical Dimensions" database
db = WEB is the commonly available data found on many web sites
db = BIG is a combination of all of the above.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
