Based on NBAA Points Model. Number of boats + 10 points. 10 boats = 20 points.

1st place 20 points
2nd place 19 points
3rd place 18 points
Etc.
No fish: deduct 10 points from lowest boat (if lowest boat was 15 points deducting 10 points= 5) All boats catching no fish would get 5 points.

I will maintain this till year's end. It should interesting to see how it works out.
Point systems were designed to promote consistency and increase competition.
Standings are governed by attendance and relative rankings instead of weight.
