I think the skeg is what I need to do (blue area in pic) although I am loathe to add more weight.

: and thinking about the submerged lateral area of the hull, there is a lot of
: boat in the water up front and very little at the rear. The bow seems to
: be sitting deep in the water. As you pointed out, putting the rudder down
: helps. Adding a skeg would also be a step in the right direction.

: It might also help to move the center of gravity towards the rear, i.e., move
: the seating position back. While this will put more stern in the water it
: will also raise the bow, which is already fairly high, which may lead to
: leecocking in a strong wind, which has nothing to do with LeeG in the
: prior post. It is the tendancy of the bow to turn downwind, which can be
: dangerous.
