Stingray~ 1,526 Posted February 25 Share Posted February 25 4 minutes ago, jaysper said: If we were going to see any foiler headless, then you would expect it to have been in the RRs in Bermuda when they boats took significant damage due to high winds. By all accounts, the AC75s need more help to get out of the water so ditching the head is a no go surely. Was just curious about if in upper-range conditions it might be legit, like with the Bat Wing for drag reduction? The AC72 wings vs these twin skin mains could make a difference, the slot might be too important. Quote Link to post Share on other sites

Fold ‘em flat then! In high tech expensive boxes / bags! (Is there enough room under the foredeck? If there were a sewer hatch?) Quote Link to post Share on other sites

The presence of a jib doesn’t exactly define a low speed / high lift / high drag aero regime anymore does it? A class cats gave up jibs a while ago, although Randy S. tried it. Once, recently. Gave it up. Jibs must be more just a handy way to change gears. Double skin wings just aren’t great aero without an inner structure to support them. And listening to KR get freaked out a couple weeks ago about main fabric tension makes me wonder how strong these things really are. Quote Link to post Share on other sites

The slot in the middle is just to compensate for the poor shape you get when you bend a symmetrical foil in the middle, like when did you ever see a slot in the wing of an aircraft? The twin skin mains have the potential to be developed to an optimum shape on both tacks. 1 Quote Link to post Share on other sites

Foiling Optimist 249 Posted February 26 Share Posted February 26 Do the 18 foot skiffs use a snuffer tube like F18's, 49ers and the like? And is it in the foredeck? that's a long sprit. That would be pretty cool on an AC in a light wind marginal foiling battle where Ken Read threatens to beat Stephen McIvor with whatever mark interval timing stopwatch it is that he keeps talking about.

We’ve been over all that, their ability to foil and turn as efficiently in the extreme bottom-end parts of it was where their smaller foils spelled death. That stats prove exactly that. Yes, and I bet we will see a lot tighter twin-skin rules next time, to save mega-millions spent on marginal gains compared to the twin-skin contraptions this time. And yes, solid wings rock!

Yes, OR got waxed in that AC35 when somehow all races were at the extreme bottom-end of the wind range, while every other day of that month was much fresher. It could easily happen that weather conditions will determine the boat winner in AC36 too. We already saw it, in the PC Finals. Quote Link to post Share on other sites

Didn’t Stars and Stripes do a David and Goliath number on a gigantic (albeit keeled) skiff-ish thing? Personally I though the mono hull was magnificent, but most people don’t agree. How big a crew would you need on a 75 foot skiff to make it work? Quote Link to post Share on other sites

If Ultimate 30’s morphed from 18’s, must be self righted by the crew without outside help, and keep on racing, no grinders, no stored power, sail changes allowed, crew of what, 6? 5? No upper or lower end wind range, allow Moth style mechanical wand center foil and rudder, that might be interesting..... or just big Lake Guarda type stuff. No more than 30’ long, period, beam 40’? No lower weight limit. No air draft limit. Multihulls allowed. National crews only. like that would happen.......but it could cost a lot! Quote Link to post Share on other sites

Kiwing 446 Posted March 11 Share Posted March 11 I would love to see a game changing CZ, one boat with one up on the foils stowing it until the next time off the foils then hoisting and getting up again. I think they will do it like the 18ft skiffs in Sydney. I wish I could find some video of a hoist, then of a take down. Quote Link to post Share on other sites

From the RRS: 32 SHORTENING, ABANDONING OR TERMINATING AFTER THE START 32.1 The race committee may shorten a course by reducing the number of legs to a course no fewer than four (4) legs or as specified in the sailing instructions for a Preliminary Regatta. A shortened course will be signalled via the RO Comms and indicate the leg that the shortened course applies to. The yachts shall finish at a finishing line between the staffs on the gate marks that end the leg signalled. 1 Quote Link to post Share on other sites
