Poor Lance -- gets two conflicting opinons right off the bat!
MMD is a Naval Architech and so knows his stuff. As such I'll ask him a question or two that might relate to Lance's post --
If thin foils are not really useful on slower-sailing dinghies, do you recommend the use of metal centerboards / daggerboards and rudders?
Or do you think that foils made of correct thickness (i.e. the dimensions all meet the recommended NACA numbers) are good but thin ones not good?
It sure seems that either galvanized steel or stainless would work really well for these centerboards / daggerboards / rudders if the chord shapes are not really important...so why use wood at all?
My friend's newly-restored Drascombe Lugger has a squared metal centerboard and rudder, which seems the best use of the metal as it puts the weight down where it will do the most good when sailing.
