Only Championship, Grade 1 and Grade 2 Events that are National Championships shall be included in the IRL. Each Ranked Regatta has an RL-factor (RL) and a multiplier (M) that may be different. In all Ranked Regattas with 19 or fewer entries a scaling factor (S) is applied.

The total ranking list points of a period are calculated as the average of the best six results of a sailor. A minimum of 5 results is needed. When (M)=2, the obtained RL-points may be used twice for the overall score.

Each result: (NoOfParticipants + 1 - FinalPosition) / NoOfParticipants * 100 * RL * S
