3 -proposed application of Porthmouth Rated numbers as an efficiency added factor applied to older existing design in original form based on class age ,-original form and design criteria.
An added percentage based on mean high average in L catagories.-

-Texel uses rated sail area --rated weight ,--rated length ,-as its base formula ,-beam is proposed factored in winspeed along with board type correcting speed potential of design in upper wind range on average.
What Texel presently can not factor is the numerous lesser design aspects of catamaran design common on older catamaran classes .
As mentioned it would take a complete individual component comparison of all aspects of each design to accomplish ,--
very time consuming and expensive ,--presently .

Rig configuration ,--mast weight ,-material ,-mast section efficiency ,-related to moment ,-. Sails ,-material -weight ,-configuration below RSA . SPIN -snuffer type ,-efficiency ,
Board aspect ,-foil section ,-depth. cant-,-rudder config weight aspect ratio. efficiency ,-hull design ,-girth station measurement ,-volume P C number . etc . partial list --
You get the idea .!!
If the idea of a rating system is to handicap boats so all have a chance to win races then this is required .So ,-another option we have is to use and apply an average time handicap --readily available --that gives a good general indication of how these lesser design features common on older boat classes effect race results . P Rating needs to correct current problems in this regard and use more consistant historic averages applied to these older boat classes .
--It becomes a combination system ,-though only applied to older boat classes that require a handicap application due to these lesser design features .
Handicap class catagory corrections would range from 1 to 3 % adjusted from the base design rating of L W SA. and windspeed adjustment .

Understood P-Rating will correct assumed creveate in system and adjust to more long term historic rating numbers used applied to older design .
Existing P COMMITTEE may work up an applied system to adjust rating numbers. Propose an average in length catagory be used based on updated dpn rating numbers.

Once established list all cat design -classes with N A Texel Rated numbers --review--

, current problem is different points of beginning and scale differences for the P rating and Texel -ISAF Rating , so scaled differences in individual boat comparison would be needed.
The vast number of boats are International Classes and have common specifications and sail areas between continents ,
Some have minor variation of sail plan and require a recalc of base rating , Performance brand cats being the main one .

Proposed - potentially -a vastly superior rating system .-
Modern cat classes do not require handicap ,-let the best design -sailing skill win based on basic boat measurement .
Allow older boat design with lesser design features a handicap to remain competitive in handicap class.

I,d be very pleased to work on perfecting this proposed N A Texel Rating with others interested .
