Nutsy,
Your 35-5 is not a dog downwind because of her keel. It is because of
that large tall main sail mounted mid ship. My Friends Benny is a damn
dog downwind and it has a deep fin keel. There is a real need for sail
pressure forward and reduced pressure on the main. The boat is
squirrelly down wind or even a broad reach.
