<br>
<br>proceeding based on I-20 specs with a lighter proposed boat weight of 380 -similar class to other existing Formulas.
<br>
<br>-We have lighter boats by 40 LBs -more sail area in the main by 14.5 sq ft than the Euro F-20 ,-it automatically requires large crew to hold this boat down in a breeze.
<br>F-18 leaves off at 330 LB s,-is this a target and logical place to pick up the 20 Class.
<br>330 min , allow 30 dead weight to min. -
<br>-What are ideal chute sizes and weights to allow more area.
<br>check 18 specs , and Euro 20 rules.-
<br>
<br>Min boat weight =380 ,-{based on Barry,s 388 weighing his I-20}
<br>
<br>MH: I would like to see more boats wieghed and probably set the weight a little higher is my guess but I don't know until we see a few more boats weighed. My guess would be 390lbs.
<br>
<br>-Max mainsail =208 sq ft -existing I-20 is 208-_
<br>- 14.5 more than existing iF.
<br>note ,other mfg. may eliminate the lower window area and increase upper main slightly ,--are these types of mods allowed or should there be an exact overlay pattern as the 18s propose .
<br>
<br>MH: The max at 208 sounds good. I don't know about the overlay. I think we need to give some basic parameters but allow the sailmakers some freedom also.
<br>
<br>-jib 53 spin 270 sq ft -same as I-20 --{no graduated jib sizes as per iF --ONE JIB max. --like the 18s ,-or should we allow mods ,--to smaller self tacking type if desired.
<br>
<br>MH: Is there a way to make the current jib self tacking? My guess is yes since it is currently run off the front beam. A self tacking jib should be almost a requirement on this boat.
<br>
<br>--Larger spin allowance increase for larger crews ---crews over 360 recieve anadded ??sq ft ,--crews over 390 LB recieve an added ?? sq ft.
<br>
<br>MH: I don't beleive this would be a productive rule. The percent difference at these larger weights is much smaller. I don't beleive that we will see anything but the largest sail area run on this boat so I think we should keep it simple with one size fits all.
<br>
<br>Longer spin pole alum or c f and c f snuffer allowed , measured from f crossbeam .-{opt for larger chutes --heavier crews }
<br>
<br>MH: Again not nessessary. But the snuffer would of course be allowed.
