Interesting to see that the foils are getting both bigger and longer, does this not sort of make one think that most of the gain is not coming from actual foil section but surface area in the water resisting up and down motion which sort of leads me to ask is this not just the same as adding hull length which then leads me on to ask is this not then making your F14 more like a F16. I am not against foils as my Stealth has them but eventually someone somewhere is going to grumble when the rear of the foil is some 400 - 500 mm behind the boat.
