If one got it right the other got it wrong I wouldn't say 'wrong', TC. I'd say 'optimised'. Although one is and one isn't, as you say. If these were designed as displacement boats for example, that might explain long, flat, wide sections, with little or no apparent deadrise. On the other hand, lots of rocker deadrise and slackness in the quarters might suggest a 'non-sticky' approach - for a hull which hopefully spend 99 -100% of its effort in the air. Interesting times ahead. Edited September 10, 2019 by Sailbydate Correct author 1 Quote Link to post Share on other sites

cport 14 Posted September 11, 2019 Share Posted September 11, 2019 When they 1st started doing runs, maybe around 1230, they used a tow boat to get on the foil. As the breeze filled in, 1430-1700, (S, SE 12kts) they were, from my vantage point, able to get the boat foiling w/o the need of the tender. I also witnessed a fully foiling jibe, but wasn't able to grab any pics. 6 Quote Link to post Share on other sites

That image (and any other from a digital camera) has been reprocessed so many times before it hit this page that it's impossible to tell if there were deliberate alterations or not. Modern cameras do a lot of processing internally to clean up and "improve" the look of an image, Instagram probably reprocessed it for posting, plus it's a screen capture so more processing. Fine detail is often lost completely, no amount of zooming or post processing will return it. Similarly artefacts can be introduced that don't exist in RL. Quote Link to post Share on other sites

Certainly the crane pic showing the flat foil is on port, so something is up If you are referring to the crane lift photo as per #2004 - I believe that is the Mule you are looking at - not the Big Mutha - so not a point of comparison. What I find interesting in the AM offical photo directly above is how little ease the leeward (slack) runner has as deteremined by the Ferrul/Block/Rigging connector - despite the fact that the mast is rotated away from it. Also, cannot help but wonder how much suction all that flat underside will create on lift off, compared to ETNZ at lift off, where finer and narrower waterlines would release more readily. I know this is against a larger and more easily driven Planing surface - but lift off requires release..... And those hinge blisters look draggy and sticky for those real light air races where lift off will enable the sort of lead that ETNZ built in that fateful light air race in SF in the AC72 cats where they ran out of time agonisingly close to the finish - but having achieved lift off had done a horizon job on Oracle. So anything that will lower lift off windspeed/boatspeed combinations could be critical and race winning. Earlier take off has been critical to sucess in the Ultimes. Otherwise great looking package. Gonna be fun watching all the comparative learnings that the teams go through until the first meet - where the bullshit will stop and real commentary can begin.
