Hope some are enjoying the night pic of Dave and me in this years Worrell . {you can right click and zoom in }Team member Chris Zander ,{also a comercial artist } made our sponsors logo {fish } from a reflective material lighting up at night ,--
A great added safety feature that all teams , sail, and sail mfg.eventually should adopt.
Always controversial crew weight and boat weight issues in any racing .
The crew weight on the 20s is less of a factor due to generous sail plans per designers and larger basic more buoyant platform ,--most Worrell teams were 340 -350 LBS some were min 325 , believe the current I-20 natl,champs are 390 or 400 LBS,--a nice wide range of proven competitive crew weights to sail .
Boat weights vary between designs ,--The F 20 rule has adopted the Tornado boat weight as min.class boat weight -376 LBS .
There also is a second catagory of boat weights for older existing designs of 410LBS and up like the H-20 , N-6-0 ,-existing Euro F-20 BOATS ,Mystere and others ,. As compensation for this weight older existing designs are given an added 30 sq ft of spin area .
Other Formula classes do this for crew weight {allow added spin area },but it is not needed on the 20s and is therefor used to compensate the differencial in existing boat weights hopefully allowing older boats to remain very competitive with this added 30 sq ft of spin area. The two catagories of boat weights 376 +LBS and 410 +have 270 and 300 sq ft spin areas respectively, -
-Here are a copy of prop.-- Open Formula Class Rules -
-OPEN FORMULA 20 CLASS

Amendments—We wish to keep rules as simple as possible and rely on good intent of sailors in accordance with standard safety requirements per sailing rules and required gear and class principles as stated. Amendments per majority vote of active class members.
The Open-F20 Committee will propose amendments to the rule if necessary. Amendments shall be placed on one year’s notice unless it is considered essential to act immediately to prohibit an unseaworthy feature. Formula 20 boats will often be sailed in Worrell type distance racing events and all components are to be constructed accordingly and sailed extensively in varied conditions before competing.
Basic specifications - OPEN FORMULA 20.
LENGTH –20 ft one inch max. —Stern to bow meas.
BEAM - 8.5 ft –max.hull point meas.
WEIGHT –two categories of boat wgt. –376 Lb. and above

-Definition boat weights –boat sails and all att gear fully rigged
Boats may add permanently fixed gear and floatation to meet min.
Corrector weights will also be allowed for boats under 376lb. total.
SAIL AREA –two corresponding categories
376 min boat wgt –MAINSAIL =210 sq. ft inc. mast --53 sq. ft jib +270 sq. ft spin, max.
410 min.boat weight MAINSAIL =210 sq. ft – 60 sq. ft jib + 300 sq. ft spin. Max.
Increases of 7-sq. ft. in jib and 30 sq. ft in spin area in 34-LB boat wgt differential.
Sail area may be traded off from main to jib of equal sq. ft to allow modification and design variation of sail plan to any max. S A combination of smaller main in category
All measurements per standard current ISAF measurement rules, --see diagrams and instruction.
-Roller furlers and main reef points may be used. -
-All teams to use the same set of sails for a regatta or distance race, but may be replaced if severely damaged to allow a team to continue racing with the permission of race organizers per event racing instructions.
Sailmakers and owners to list sq. ft in 2 inch numerals at the tack of each sail next to the sailmakers logo with signature over. All sails are to be commercially available to any sailing team. Existing class cat designs will be accepted as listed per mfg. or sailmaker. -Racing will be on the honor system, but any boat may be challenged and checked along with the protesting party also being checked for weight and sail area compliance. Those not in compliance will be DSQ for those races.
CREW –One or more may be crew. -All must be capable of righting from a capsize.
