      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

THE NEW GENERATION OF THE SUN FAST 3200: R2 VERSION

 

Always at the forefront the latest demands and trends, Jeanneau is launching the new generation of the Sun Fast 3200.

 

The Sun Fast 3200 R2 benefits from three major new changes to appeal to the high-end sailboat racer: the open cockpit, the carbon mast and the straight keel. These three evolutions ensure gains in speed, fluidity and ergonomics.

 

So, new keel = better upwind performance amiright?

I would think the bulb keel would be better for short handed sailing with the concentration of weight lower down,

but the new fin would have less drag for fully crewed racing. Certainly looked that way at Commodores Cup 2016 when designer Daniel Andrieu

kicked serious arse with the newer version as part of the winning French team.

We have specced a new 3600 due to arrive shortly and went through the same discussion with the designer. The bulb keel ultimately has a lower cog but the fin keel has lower drag sailing downwind and tracks upwind better particularly in light airs, the fin keel is also fully lead and doesn't rust like then bulb keel does (there were some issues with 3600s with rust and some got retrofitted with the fin keel

IRC optimisation and lower wind drag.

The R2 is based on the many changes made by the architect Daniel Andrieu on Cifraline: keel, rigging, stern box/rail...

Actually I look at it as “IRC adjusts” for any changes made to a boat. 

Yes, but the common wisdom seems to be that the penalty for a bulb is more onerous than the speed gain. At least this is what jpk seems to think.
