Criteria for handicap classification and handicap factor added CALC;
NOTE; applied to older catamaran design with lesser design features partially corrected per rated weight -rated sail area rated length ,and board type allowance rating factors.

1-Age of class 10 years or more ,-boats in original unmodified form .
2- Design features common to older catamaran design including but not exclusive only to
A Heavier boat weight than average per class listing
B- -Larger heavier mast section ,-fittings and rig ;plus sail material type
C;Sailplan configuration below measurement limits ;lower aspect ratios.
D---less efficient low aspect board and rudder configurations
E---Hull configuration & type ;forward 3rd beam;deck edge o h and misc .

Note; any class may petition for handicap added factor to rating per criteria-outline
Inc. Catamarans above 22 ft generally in modified form per owners specs.
Trimarans and proa configurations rated per separate integral category .


All modern catamaran design development and limited development Classes.
Including all A Class ,-Tornado,-18 sq ,all Formula Classes do not require handicap added factor .
Larger classes generally in modified form .-per individual boat specs .
New catamaran classes receive a calculated base rating along with all modern cat classes as well as all modified existing classes with spin;snuffer systems and other modifications added.

Note; Older existing boats modifying w spin snuffer would also be encouraged to update and modify sailplan to a modern lighter safer one per Formula rating target in Length category, but may recieve a spin only added rating .

Listed for handicap classification ;and handicap added factor per DPN rating-
DPN to revise current ratings .
Handicap added factor to be averaged per current modern design rating per target rating in Length category .
A .50 average applied to older lesser design features as listed, -being compensated and corrected in scale per dpn rating numbers to comparable Length modern cat design non spin per Length category.
Estimated average .50 is corrected in handicap per rated weight ,-rated sail area ,measurement proceedure ;rated Length -non board type , currently in base rating .

1.545 conversion factor from Texel to dpn rating to establish target modern catamaran design rating in each Length category based on current Formula class rating no spin,--per rating conversion. {thanks Sam}
Example Tex. rating Formula 18 no spin =106 / conv factor 1.545 =68.60 {per list below} r.to 10ths

22ft modern cat design target dpn =60.60
21 ft target dpn=62.60
20ft target dpn=64.60
19ft target dpn= 66.60
18ft target dpn= 68.60
17ft target dpn= 70.60
16ft. target dpn= 73.60
15 ft target dpn =76.60
14 ft target dpn =80.60


Example ;Calc. For H A F --[Handicap Added Factor} --
14 ft ;category

Example calc
;dpn target rating for modern comparable cat rating =-80.60
Hobie 14 design cat rating per current dpn rating =86.9
H-14 dpn ;86.9 ; 80.60 the difference being 6.3in dpn rating from modern cat design rating in Length category .
Rated target rating using conversion number and formula rating numbers in Texel compared to H-14.current dpn rating.
We have a conversion number from dpn scale to Texel established at 1.545
1.545 * 6.3 = 9.73 *.50 =4.86 ->-5
Tex rating of 134 + H A F 5 = 139

H-16 Example calc.
H-16 target 73..60 dpn =76,1 =2.5 8 *1.545 *.50 = 1.99 H-16 117 +2 =119 rating with H A F

The added H A F {Handicap Added Factor } per dpn rating will theoretically adjust rated time allowance to the equivelant modern cat design in Length category .

Again due to lesser design features common to older catamaran design as listed above not fully factored into basic design rating of rated length weight and sail area.

H-20 Miracle original form dpn rating 64.9 target 64.60 .30 81.545 =.46 =rounded < no change in rating 101
typ. non spin 20 rating 100
rated up in N A for added S A

Rating target in each length to be seasonally updated per recommendation of Rating Committee.
Dpn numbers would be converted to H A F numbers for each class listed below, then added to adjusted new rating per revision and wind speed modification factors also added .

Note; non board types per example will drop 2 points per windspeed factor in upper range.



Classes for added H A F - older classes with lesser design features per criteria outline.
