Can anyone suggest the best and simplest scoring system to select a 'Champion' boat across all Divisions/Fleets in a 20 race series with 4 Divisions, with Division sizes ranging from 10 to 20 boats?

Fun thought experiment. Can you confirm these are different types of boats, and there is no handicapping? If the fleets never race each other, and you have no way to handicap their level of competition, then all you can do is compare the quality of the wins.

I believe you pretty much have three options:
  1. select the boat that was the most dominant in their fleet (basically low-point scoring)
  2. select the boat that was the most dominant in the largest fleet (basically high-point scoring)
  3. create a hybrid system (basically average the two)

The advantages of each (of the top of my head) are:
  1. most obvious... if you bulleted every race, you're going to look dominant
  2. encourages fleet participation (at least in the present day) and maybe reduces incentive to "drive up the score"?
  3. possibly does both? or neither?

What are your goals with this award? Remember that more fun will ultimately drive more participation.

I would suggest the Percentage of Perfection score.

If it's not the same as the Percentage of Perfection system, take a look at the system used for the IRC European Championships.

For the RORC UK IRC Nationals they use a formula based on the number of entries in the various classes and the number of races run etc. 

I don’t have the formula to hand but I’m sure if you contact the club they would share it with you.

It isn’t a perfect solution but is the benefit of being a formula used in a championship event.

Thanks Everybody for the responses.

Niko, Fun thought experiment. Can you confirm these are different types of boats, and there is no handicapping? If the fleets never race each other, and you have no way to handicap their level of competition, then all you can do is compare the quality of the wins.
 
Races are Friday Twilight races.  Jib and Main only.  Sailed under PHS empirical performance handicap (rolling average speed index, golf handicap).  This rewards consistently well sailed boats.

Boats are mostly conventional [heavy] keelboats from 20 to 65 ft, with 4 or 5 Flying Tigers and a couple of sportsboats, not very powered up with JAM only.  Four divisions based on size/speed, each sailing slightly different courses, depending on their size/speed.  Divisions entrants vary from 10 to 20 boats.
