In Sailing, there are a couple of rules that apply to this situation and the details are in the one-design class rules and their applicability... I'm proposing changes to my local "one-design" class rules because they are archaic.
Basic Principles:
SPORTSMANSHIP AND THE RULES Competitors in the sport of sailing are governed by a body of rules that they are expected to follow and enforce. A fundamental principle of sportsmanship is that when competitors break a rule they will promptly take a penalty, which may be to retire.
Part 1 Fundamental Rules
Rule 2 - FAIR SAILING A boat and her owner shall compete in compliance with recognized principles of sportsmanship and fair play. A boat may be penalized under this rule only if it is clearly established that these principles have been violated. The penalty shall be either disqualification or disqualification that is not excludable.
Rule 69 - MISCONDUCT
69.1 Obligation not to Commit Misconduct; Resolution (a) A competitor, boat owner or support person shall not commit an act of misconduct. (b) Misconduct is: (1) conduct that is a breach of good manners, a breach of good sportsmanship, or unethical behaviour; or (2) conduct that may bring the sport into disrepute. (c) An allegation of a breach of rule 69.1(a) shall be resolved in accordance with the provisions of rule 69. It shall not be grounds for a protest and rule 63.1 does not apply.
