Hi Wayne,

great writeup, thanks!
I have never tried an A, but they are impressive. Even more so with a spin I would think. Add in the curved foils they are developing and it looks great!

Could I ask how old you are Wayne, as you wrote: "but my guess is at some stage health and mobility will dictate that an A may well be back on the cards ".

How did your experimental snuffer work out btw? That is really something to work on! Drag reduction.

About foils for our boats. I think we will want to measure them in as F16s. Curved foils are out of scope for now.
Installing A-cat foils is a real option.
Do you have any links to where I can find old A-cat foils?

As a gross estimation, foils needs to be about 2% of the sailarea. Would be interesting to compare current and 5 year old A-class foils to current F16 foils!

Klaus, I have shamelessly taken a look at your modified NACA0013 profile and unless we find foils we would buy, might use that one. Do you have something similar for daggerboards? And what about planform.. Would you be willing to spend a few minutes thinking about that?
