  1. The way i remember the past is that the Tornado came out first in the late 60's, taking the fastest production sailboat honor from the Shark (also 20x10). My first crewing gig was on a Tornado 1968. The hobie 14 came out also late 60s. Tornado wasn't used much in the Worrell since it isn't good to run up on the beach at full speed because of the centerboard gaskets for one thing. There was a 10m foot wide alfa cat from the guys that made nacras before the 5.2 came out. The 5.2 being more like a tornado as an answer to the popular hobie 16. we destroyed the naca 5.2 fleet in sfo multih
  2. here are some yellow lines on a nice pic from this thread of fairly powered up TR.
  3. pretty good chance that all the racing is over in NZ. it appears that ppl are afraid to go out and help run the race. just sayin, hopefully im wrong
  4. It's possible that Prada boat was made 10% faster before they took on AM the last time, just like they said. They seemed to pull away downwind in the last couple heats. Also the mainsails might be faster on Prada.

  6. i wonder if they will take the guy who left the backstay on, off the boat in future heats?
  7. electronics on a wet boat...most of the AC foiling heats and other foiling heats with coms, that i have watched had at least one boat having problems with an electrical component... sometimes it's intermittent, sometimes it ends the heat for them, sometimes they loose because of it, but still finish. it seems to be part of the game many times. Ineos didn't seem to know where the boundaries were in the previous heat for example. p,s, great job getting that boat back to port with that size of hole in it.
  8. I saw them pull the traveler up to windward right after they lifted the foil after a tack. almost like pumping after a tack on a board. I wondered if maybe they could also pump a little more sometimes in the lighter puffs. the cats also pulled the wing past center a lot, so it must be good for some things.
  9. They used claim catamarans started in bora bora. Now i dont see a reference to that in a search. Searching is difficult these days because of all the info and advertisements using similar terms. This site claims that brits first saw them in india. https://www.newworldencyclopedia.org/entry/Catamaran this one, Polynesia. https://encyclopedia2.thefreedictionary.com/Catamaran+History The first voyaging canoes with twin hulls were Polynesian and they could make ground to windward. during the same time period, old square riggers from europe could not go above a beam reach very wel
  10. What about complete wet laps? They are saying the race will be during a light air part of the year. If wind is steady enough it looks like they can do everything a moth can do as far as staying airborne.
  11. It makes sense that the flow from the windward side meeting the leeward side aft of the leech would be less drag than if they, the air flows, met right at the leech. (gap between leechs vs. no gap) i wonder if full wing mast/sail as on the cats should be made with a fat squared off trailing edge as well? or maybe they were?
  12. there probably wont be any problems with electrical systems, hardware, software, or firmware in a salty wet environment:)
  13. A big mast like that with uppers and lowers that rotates is a bit of a puzzle. I wonder when they will show how that works, if ever. The twist controls must be interesting too. Maybe they had a problem in one of those areas...
  14. Leeway. Anyone mention that? Even if a sailboat could regularly point up to 30 degrees, which i seriously doubt, they maybe won't tack on 60 degrees because of leeway. That means they would go past the 60 degree layline before tacking. Leeway will affect VMG, as does the bearing off to pick up speed to then gain height. My apologies if that is too obvious.
