Tillerman just posted about planing RS Aeros and courses designed for planing singlehanders. This brought to my mind the D course I modified* for just that and the unintended but humorous results when I sprang the D Course on the unsuspecting Classic Moth fleet at their 2013 Nationals (hence the moniker "Dammit" course).
* Tillerman points out that what I've "designed" here is really a Harry Anderson course, a course that has been around for eons - and he is right - but the D course is a Harry Anderson with modified reaching legs. (See Comments)
I still think the D course has potential. For hiking, cat rigged singlehanders the fastest planing angles seem to be just below a close reach, or a course slightly lower than 90 degrees to the wind. I remember as a PRO back in the 1980's running a Chesapeake Bay Olympic training event and the Europe dinghies had something similar, though if my memory serves, they ran their close reach into an extra mark about 1/2 way between the windward and leeward marks. When the southerly came up, on that reach, the Europes really scooted.
The D course has a curly-cue rounding at the leeward mark. A starboard rounding might be better but I have found that racers are so attuned to going around marks-to-port that they get confused when you change this up.
I offer up the D course details in the following PDF. I'm always interested in what other racers or RC thinkers may come up with in designing planing courses for hiking singlehanders. I think one of the keys is to come up with the angle to the true wind your singlehander is sailing when it is planing the quickest. Data anyone?
