Having owned a Vivacity (built to Lloyds A100) on the Chesapeake Bay for
several years (1970's) I would recommend either a shallow fixed keel (Cal
20, D&M 22). Both have fixed keels, 3-feet deep, and are stiff and stable.
The twin keel design places the keels slightly pin-toed so that your
downwind performance is sort of bleak. Perhaps if you could find a
Snapdragon 26 (also Lloyds A100) you would get better performance. The
Vivacity had the keels glassed in and they were quite thick. If you run
aground even slightly you do not rock a twin keel off the bottom. On the
other hand you can put up enough sail to actually pull one of the keels out
of the water on a Vivacity. If I can locate a photo of us doing it I'll put
it on the web. My current D&M 22 does a fine job sailing the Key Largo
area - inside when the ocean kicks up and outside when it 3 feet or less.
Also check the mast and boom length on the twin keel. On the Vivacity the
mast was very short and the boom very long. On the plus side, a twin keel
doesn't need a cradle when you pull it out.

Neither. Twin Keel is the best choice.
