Thanks Stewart, I meant that discussion around whether a moth is faster than a F20/Tornado/my mother-in-law on a skateboard does not belong in this thread, since it`s about F16 & wings/racks.
Now I have another question - if this is an ISAF rule (one foot on the boat) then does this not outlaw racks on all classes, how do the I14s, 18fters etc manage this ? What I understand is that F16 is not an ISAF registered class, does this mean they can ignore ISAF rules? This seems contetious as we all sail under the RRS which is administered by ISAF. And I`m still no wiser regarding how racks are measured in the F16 class, is it platform width plus ONE extended rack, even if the racks are fixed, not folding ? That`s how I understand it.
Not that I`m going to put 30cm racks on the Mozzie, just interested in the rule interpretation. I don`t think that it would change much and would add a whole lot of extra hassle, as most have said, wider beams would be the better option. (And higher-volume hulls.. and a taller mast.. might as well buy/build a proper F16 then.)
