  1. So much talk was already about the foils, what im curious about is why Italians who are in really good stable control of their boat fly the hull so high, especially at high speeds. I think they do it intentionaly. Is the pressure at the hull height really that beneficial to VMG or is it worsening it by pushing boat away from course. Can italians with their hull shape and leaving some gap create venturi effect under hull at high speeds to suck their hull down and increase righting moment? Its strange because Italians have never bothered with batwing sail to lower point of power delive
  2. I dont know if i drawn it totaly accurate but to me shape of American Magic Patriot has the weakest hull section in case of flat impact like it happened. It has preety flat sides with just slight curvature outward, in case of impact forces can flex this curve from outward to inward and that might cause that long crack that continues from hole towards the bow. ETNZ Te Rehutai might land even flatter since it has concave hull side, but hull is already turned inwards so it would spread forces more evenly, some cracks might still occur. Luna Rossa and Brittania have more curve to handle such impac
  3. I noticed that too, but dont have explanation. This occured at the same moment foils slammed the water hard. The second impact was when boat hit the water. Im think most of the damage was done with second impact.
  4. This new photo totaly confirms my theory how that hole was punched.
  5. Patriot is flawed boat, its cross section is like martini glass, while other teams have more rounded cross section. This martini glass flatnes really isnt ideal since flat panels are structuraly less stiff than rounded, especially in case of landing flat on water like they did its prety obvious that those thin panels take lots of force. Since force is transfered through internal ribs/structure the weak points are in between those two. That also explains that square shapped hole. There was part that fell off the boat, it looks twisted. Perhaps hole as it is was created that one of the corners o

  7. Terry just confirmed my theory, that pressure broke a hole between two bulkheads.
  8. Some are suggesting square batteries caused square hole, i say to you this is not a cartoon. Even if such object would land flat on hull wall it would have least penetration force due to large area + that it is opossed by pressure from outside. What many are forgeting is that those boats have bulkheads, and bulkheads are perpendicular to each other. So if cracks appeared on joint of skin to bulkhead due to strong impact pressure they would crack. If one of those cracks opened and caught fast rushing water (boat was still moving fast) it would open like a tin can. It might be possible though th
  9. Yes but the skin is thin and its the first one to show where there was structural stress. Judging from those other photos i now only see two crack lines, as drawn in image. Hole seem to be boxed between ribs/bulkheads of the boat, and since there is some carbon tear at the bottom it probably opened like tin can from top to bottom. Maybe something hit it from the inside to start this cracks fail totaly creating loose slab that was ripped away by fast moving water on impact. I added screenshot of ETNZ hull design with bulkheads spacing, im sure Patriot has different spacing but it makes total se
  10. Check again this image, you can clearly see half rounded line that is really evenly distanced from arm and suggests this is reinforcement of arm into the hull. Even hole in bottom part isnt square in that corner since this circular crack intersects it. I think this is the biggest structural problem they will have to face. Hole is the least problem, but hull cracked in places where it is supposed to be strongest is a problem.
  11. Well, ETNZ stated it took them 8000hrs to build the hull. So if you have 50 man and 12 days, each man working 16hrs per day its 9600hrs. But this is theoretical, the first issue would be they dont have molds on site, or do they? But then again, many things can be salvaged from this boat, it would have to be only partialy rebuilt. This will be organisational and logistical race with time.
  12. Well, exactly what i pointed previously. Means its really bad damage and lots of work to repair.
  13. I dont think they will be able to repair it till friday. What happens if they miss this deadline, could they skip 2nd weekend races but still go to semifinals with whoever is going to be a looser between Luna Rossa and Ineos? Based on points right now they would probably battle Luna Rossa. Skipping next weekend would give them about 12 days to repair boat.
  14. Well at first i thought it must be part of the foil, but it felt strange if foil since its 100% carbon and i doubt it would float. Only logical explanation is that this is missing part that was broken away on impact.
  15. Well, when looking at this image and also some video footage, reflections are showing crack lines, this is how I see them. Notice that half circular crack in front of arm reinforcement. Thats structural damage in my opinion.
