^ i was watching from Maraitai on sat early afternoon, there was a lot more separation between the 2 boats then what this video portrays. hard to say who was fastest as they were all running different angles they don't look like much with their sails down being towed around but as soon as they...

yellow line brigade thanks you

that is B1 about to be loaded onto a ship ... B2 will be flown later

with the race area's in Auckland I don't think you will need to worry about 2m + swells. if you are getting those coming in from the NE then your wind limit will be well over

looks like jimmy has brought along his twist grip to LR ... wonder how long till he needs to break out the camo version

now I'm beginning to think I'm useful around here :lol: ... GD, I'm awaiting your private message to join the crew (happy to work from home but will expect to tag along in a chase boat at some point) I can't do much with those as they are no-where near square on (I'm sure there is a way I...

that 7.76 degrees is the difference between hull level and my approx guess at the straight part of the foil arm ... nothing to do with overall heal (trying to find out if AM have their foil rotated at a different angle to 'fly lower, with increased RM')

is that actually available??? might have to bring a few more beers as long as the racing is App viewable so you can follow the living racing what a mint spot to watch it from

hop on a ferry and walk up Rangitoto with a deck chair, snacks and a few cold beers. A,B,C,D covered

speed only counts it they make it to NZ :lol:

any chance you can source the video for the 'eagle' cant say I've seen it

im still doubting the 2 foil in the water theory. simple force diagram ... if each foil is supporting approx half the weight of the yacht you have no righting moment, any breeze would lift the windward foil out of the water, you wouldn't be creating enough lift off one foil at that speed so you...

not disagreeing with you there. there will be a ratio between main foil size and rudder size. I was referring to general foil size required to lift boats out of the water

would be interesting to do the basic calcs for which boat foil is more loaded per m^2 of foil size AC 50 = 2,332–2,432 kg AC75 = 7,600 kg (16,800 lb) loaded at a guess would you say the AC75 foil area is 3x that of the AC50?

so to gain maybe the 20% more lift they need you are suggesting doubling the drag in the water ... seems that could lead to slowing rapidly as they have less apparent wind and would drop into displacement mode from what we have seen these boats can foil in 6knts of breeze, ill take a guess and...

I'm not disagreeing with you but curious as to how you think the mechanics of 2 foils in the water allow you to point further downwind ... I'm sure we would have seen this on an AC50 if it was helpful same again for stability comment ... surely more weight away from the pivot point (as wide as...

I'm not suggesting that the LR boat has an adjustable length but the intersection stepped joint is similar back in my uni days a couple of friends were looking at the aerodynamics on the above joint for wind turbines (adjustable lengths depending on the amount of wind) as we all know on...

think you have nailed it here. rounding the bottom gate with a boat infront/behind you. you want to put doubt in the other teams mindset ... are they tacking? do we need to cover etc etc its the equivariant of the old school boats doing a fake tack

the Auckland mayor Phil Goff is putting forward international students to be allowed in Asap with a 14day lockdown in hostels because they bring in heaps of $ into the city... I wouldn't be surprised if the cup teams have a proposal in the works along the same lines.

spot the difference :lol:
