Ok, I'm really embarrassed now , but I think that I should have used
the term "swing keel". See the link shown below. This is what the thing
looks like. The caption on the photo says "Infamous Wing Wing
Keel"---which is were I got the term in the first place. I think that
this "keel" is more like a centerboard or daggerboard (maybe). Anyway,
apparently this keel has at least two positions completely "up" and
completey "down" ---or maybe more---I dunno. Anyway, assuming that
"SWING KEEL" is the correct term, how dos the thing work and how do you
let it up and down (...maybe with a rope...er...I mean a sheet).
Thanks, Jim
