Absolutely right John, the rule giveth and the rule taketh away. The idea is to choose the set of compromises that suit the expected conditions, these things are incredibly specific to the race venue hence all the weather and wave data that the challengers collect for the years before the finalisation of the design.
As to seaworthiness have you noticed old NZL 20 out playing ocean racers in the coastal classic? Went pretty well too I understand.
A lot of people wonder about the very blunt entry on the bows of these things, it is to lessen the entry angle from there back . The blunt bow angle presented at a very shallow angle gives less overall resistance even if the bow wave up at the surface looks messy, is the total wavemaking that is the target.
I had a very interesting hour in the shed at Mascalzone Latino base just before the end of round one, so near and yet so far, interesting stuff even if they were the first to be knocked out. JohnW
PS, I'm glued to the telly every afternoon that I can make an excuse to be there, and will soon be taking Huffboat up to spend a day rowing around the bases taking photos and drawing sketches of the interesting bits.

I’ve been wondering about those ugly knuckle bows we first saw on the NZ boats a few years ago. I assumed that they were tailored to our particular chop and dampened the pitching moment somewhat but a friend tells me it’s much simpler than that. Yup,,. Rating.( the rot sets in) Apparently this class measures it’s waterline 200mm or so up from the actual waterline. If you snub the bow you shorten the measured WL and get something else in return. Ballast or sail area I assume. I’d be interested to hear from someone who knows, if this is true.
Some dramatic and aggressive sailing yesterday. Probably the big one being the Prada Alinghi match up with a communication error between bow and stern on Prada causing them to slap Alinghi across the backside. Great shots leading up to it with Prada burying her bow in Alinghi’s quarter wave. Fillets of water hosing up over the bow and water which looked up to the deck at times. Alinghi won today too.
Oracle beat One world yesterday and today. Todays race featured on TV. Get this. Oracle leading to the last mark and on the bear away set ,a muck up with the brace meant the spinnaker pole broke against the forestay. They held on though.
I’m on record ain’t I. I like Oracle. She’s looking dangerous.
Stars showing GBR the way today after yesterdays loss. SWE beat Le Defi both days and looking dominant.
An expert is but a beginner with experience.
