This is what happens when you let your engineers loose to dream.

WOW! That's cool. They sure get a lot of lift from those.... eh.....wings(?)

I wonder what water foil (?, can't say air) they use. I'd like to see that sailboat zip across the Pacific.  ;D

So totally cool!!! When I sailed (Raced) as part of Fleet 204 Oneida Lake, NY all over the NE using my Hobie 18 Magnum in my 30's I never thought a monohull would ever outclass a catamaran. The days of telltales are long gone here.

Absolutely awesome technology, but to be honest I miss the yachts.

Back in 1982, a friend that attended Cal Poly Pomona with me in mechanical engineering selected as his senior project the design and fabrication of a set of foils for his Hobie cat. He cut the upper surface to a pure arc since that he felt it would be adequate, but also because it seemed easiest at the time. He used a very large barrel fixture and mounted the foil blanks on it and turned the whole ensemble on a huge lathe. As I recall, in the test phase he was able to get it foil-born, but anything that disturbed the boat in pitch required a lot of luck to stay up. He used some type of float on a lever arm to automatically adjust the foil pitch.

Seems like forty years and cubic dollars has advanced the concept a bit....

It's not really beautiful, but looks highly functional.  It appears they will have (maybe already).  Thought I saw that they would be racing.

Me too!  They are much "prettier".  The pros probably don't like that they can be very evenly matched.

Well; technically it's not a "monohull" at all. It's a "Hydrofoil"

The telltales are still there (probably even more so now), the big difference is the apparent wind direction.  When you are traveling 3 to 4 times the wind speed you are looking for pressure in front instead of behind.

  I have always had an interest in the Americas Cup event, but haven't paid much attention to it in a lot of years. My how things have changed!! Anyone know where I can read about the current current trend ion design and how they function?  I notice also after watching the 6th race in the finals tonight that they don't don't run a triangle course any more, apparently to not have to make a down wind run. I always liked to watch the sail and course changes!! Talk about team work!!

I do miss watching them set the spinnaker. That was the sailing analog of a pit stop in motor racing.

ETNZ does have a hybrid code-0 that can furl (automatically) but likely is effective at a wind speed below the average strength needed to start a race.

Isn't it a monohull craft with a hydrofoil plane in the wate?
