Apologies if people have been over this already. I read a lot of old threads on here but still found some aspects of the Keel that weren’t discussed.
The Keel is a very nicely made (and very nicely finished) product but the strange thing to me (from how good the reviews are and how much it's rated over something like the Greenstreet copy) is that I don’t see any special magic in the design….To me, it looks simply like starting with a desired shape, fixing points, centre of gravity, then we need to machine it from solid, so the 45 degree webbing is introduced to reduce weight without losing stiffness.
Maybe the webbing also serves to increase surface area for dispersing vibration? I don’t know but the layout of the webbing doesn’t look to me like it’s done with any special mathematical formula or specific attenuation in mind (unlike the Rubykon, for example). It’s regular….The only “unusual” part I can see is the shallower pocket below the spring mount hole near the motor position (maybe for balancing CofG?)
Is there some feature of the design that I’m missing that makes it special?
