Recent ARRL Antenna Books have contained a series of optimized monoband
designs for 40 - 10 meters. Among those is a three element 20 meter
design on a 16 foot boom. You may want to get a copy of any of the
last three editions and check it out.

I've been out of the loop the past few years and my ancient tri-bander
has bought the farm. I'd like to replace it with
a three element home made 20 meter yagi for which I have a candidate 18
foot boom. My old ARRL handbook indicates
element spacing in the neighborhood of 0.2 wavelengths is a good
compromise. I realize we are in an era of computer
optimization and I'm open for suggestions on how to proceed with the
project.
