: Hadn't noticed that this was one of Nick's designs. You'll want a
: pretty tiny sail, no more than say 40 sq. ft. of sail and that
: being fairly low or you'll have an "interesting" time
: sailing her. Generally the dagger board should be slightly in
: front of the center of effort of the sail. The center of effort
: of the sail is usually about 25% aft of the leading edge of the
: sail (depending on the sail plan). So...you'll need the sail
: before you can compute where the dagger board goes.

: Bill H.
This may help answer my quandary of daggerboard position. Having the DB slightly forward of the sail's COE would then give the boat the preferred weather helm? I have to admit that choosing the sail plan and then the DB position seems bass ackwards, but makes sense. Maybe having these guidelines will push me over the edge and convince me to install the sailing rig.
Thanks much,
Harry
