I just adjusted the keel to be at the skin line like you are talking about.

: I'm seriously thinking about a wood frame, non-folding, Sea Pup for
: my
: son. He'll have more fun in his own boat instead of riding up front
: in
: our Chuck 15. The Skinny Mouse he's used has proven to be too slow,
: too
: wide, and too wet for his taste. A photo on Tom Yost's wood frame
: manual
: has me confused:

: Why is the keel drawn projecting down below the keel offset?
: Seemingly
: by 1/4 inch. I see how the outer edge/corner of the chine and
: gunwale
: line up with the offset for those coordinates, but that extra keel
: hanging down has me scratching my head. Shouldn't the bottom edge
: of the
: keel line up with the keel offset?
