Rules: OCS and on the water penalties

There have been a number of discussions recently as to whether there are any local rules with regard to OCS and on the water infringements. As it stands today, the rules are as follows (in layman's terms):

1. OCS - sorry you have to return and clear the start line (there is an amendment for the Tideway Series)

2. On the water infringements (excluding hitting the mark) - twice round.....720 degrees

3. Hitting the mark - re-round it again without touching the mark
