It is not seamanlike to compel a boat to touch a mark even if she does not break a rule by doing so. 

The race committee vessel becomes part of the mark when the race committee intentionally attaches the vessel to the mark, therefore, a boat racing that touches the race committee vessel breaks rule 31.

The definition Keep Clear (b) is a test that decides whether a boat is keeping clear of another either under rule 11  or under rule 10 when sailing downwind on opposite tacks, while rule 16.1 puts a limitation on the rights of a right-of-way boat.

A boat may protest or request redress for an incident during a practice race. If there is damage to the boat entitled to redress such that repairs expand over subsequent races, redress may be given for those races.

The Notice of Race or the Sailing Instructions of an event can change or delete rule 55.

Authorizing a club to organize an event does not make a class part of the organizing authority.

The Post-Race penalty under rule T1(a) is not an additional penalty option available to boats at the time of an incident. It is only available to boats realizing that they might have broken a rule when it is too late to comply with rule 44.2..
By knowingly breaking a rule and not promptly taking a penalty, the boat violated a fundamental principle of sportsmanship, therefore she also broke rule 2.

When a finishing line inflatable mark drifts out of position, the race committee can properly substitute it with a vessel displaying flag M and making repetitive sound signals.
