Has this been done before?

The universe is 6 dimensional.

Just how may degrees of freedom (variables) are there to consider at any one time in dinghy racing? E.g.

The course is two dimensional = 2

Sail controls: main-sheet, jib-sheet, mast rake, kicker, cunningham, outhaul = 6 (total 8)

Does any other sport come close (which and what score)?

We must be gods!

Mast rotation

Fore/aft trim

Batten Tension

Plate heights (same on both tacks, or lift the windward one ?).

Diamond tension; slack and let the mast bend, or tight and bend the mast

Spreaders flat or raked.

Rig tension

All race courses are at least 3 dimensional as they exist in time as well as space.  Predicting windshifts is time related as well as space related...

And depth too, as my dagger board often discovers!

Bigger picture: wind direction, windspeed and rate of change of both

I was wondering how many fishing has, Britains most popular sport ... sunny, raining, erm ....
