Geesh, man... all I did was ask you why you think Oracle is slow. I just don't think that subjectively evaluating videos is much of a measurement system. Heck, I thought LR would have had something for NZ with all the training they've had together (looked fast?) but clearly they're not in the same league.
Bows are definitely smaller for less weight and less aero drag ,but it also appears that the tradeoff is lack of stability. Most of the videos I've seen('cause that's all we've got to go by) shows Oracle's foiling is comparable to a baby giraffe learning how to walk, pretty wobbly and erratic, which as you know changes foil angle and increases drag, decreasing speed. Will the weight gain and reduced aero drag make up for it? I doubt it. It has gotten better with more practice and I hope we're not seeing the best for Oracle and the matches sake.They still have plenty of time, but at this point I'd venture they are still playing catch up. ETNZ on the other hand has, for the most part, mastered horizontally stable foiling.Maximizing their efficiency. You also need to remember no ones designs (except ETNZ) appeared to take full foiling into account until ETNZ did it.
Not sure if you were watching the same race I was... but ETNZ was having their fair share of difficulty staying up on foils.
They certainly looked like supermen compared to LR - but they are not without fault.
