- Boats are eligible for scoring if the owner is an Active Member of Fleet 6 and the J/105 National Class Association.
- All boats participating in Fleet 6 Races must comply in all respects with the Fleet 6 rules, which are identical to the National Class Rules except for the next bullet). See
http://www.j105.org/docs/KeyRules2011.pdf for a one page summary of the class rules.
- Boats that did not finish in the top five in the 2010 season standings are allowed to carry one professional (Cat. 3 sailor) on board as a coach for one weekend of racing. The coach is exempted from the crew weight limit, but cannot hike, trim, steer or otherwise sail the boat.
- A valid weight certificate is required as per the National Rules to be scored for Fleet 6 trophies.
- A boat must participate in 51% or more of races on the Fleet 6 High Point Schedule for her score to be considered for the relevant series. The High Point Series is the Fleet 6 Championship.
- A boat will be allowed to discard every seventh race for the season series.
- For both series, the Cox-Sprague Scoring System will be used with only eligible member yachts being scored. In this system, higher points are awarded for better finishers. The boat with the highest "Percentage of Perfection" wins. Discards are based on lowest individual race "Percentage-of-Perfection" scores.
- Trophies will be awarded for the Season Championship Series. Additional trophies may also be given in the discretion of the fleet 6 officers.
- Any issue not covered by rules above will be settled by the RRS, as modified by the prescriptions of US Sailing. If there is no relevant prescription, Fleet 6 officers will be the sole arbiter.

| Cox-Sprague
Scoring System |
| |
Cox-Sprague scoring system recommended by Y.R.A. of L.I.S, modified as described below
|
In each race
the number of starters will determine the column to be used in the table below,
and each boat will be credited with the number of points indicated for her
finishing place. A boat's series score shall be her "Percentage of Perfection" calculated by dividing her total points scored by the total points she would
have had, had she won every race in which she started. A boat which does not
finish or is disqualified in a race shall receive a score for the place one
greater than the number of starters in that race.

For those who enjoy it, the fine print...
For finishing place n > 20 a boat will be awarded the integer value of 59 - 2*log( n-19 ) points. Fractional finishing positions awarded to a boat by the race committee or by a decision of the protest or appeals committee will be credited with points interpolated linearly from the table.
Modifications made to the original Cox-Sprague Scoring Table:
- For races with 2 boats the original table appears to have an error. To be consistent with 68% Percentage of Perfection for dead last in a 3 boat race the "4" in the column of the original table corresponding to 2 boats should be a "7" giving a 70% score rather than a 40% score.
- In races with a high number of starters, the extension to the table for finish positions beyond 20th place is to award points equal to INT(59 - 2*log( n-19 )).
