Does anybody here have direct experience of changing between fixed, folding and variable / feathering props on the same boat? I'm particularly interested in hearing from anyone who has instrumented documentation of exactly how much difference the folders etc. improve sailing performance over a fixed prop.
This subject is a bit like anchors - "everybody" knows that fixed props "kill" sailing speed, but it's all seat of the pants opinion as far as I've been able to determine. I've never seen any sort of documented info on speed differences between different types of props on the same boat.
The reason I ask is that I have learned that there is a wide variation in what sailors regard as significant. In a conversation with the previous owner of my old race boat, he spoke of a change he had done that made a "Huge difference, Huge" - I later discovered it was 1/10th of a second a mile. I guess it mattered at the Worlds but it sure wasn't something I'd spend money on.
Is that the sort of thing we are speaking of here or is it more like a knot on a 33 footer?
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
