I'm working on some sailing instructions for relatively informal club PHRF racing and am debating whether or not to offer arbitration. On the one hand arbitration offers an expedited means of adjudicating protests, but on the other hand if the arbitrator isn't permitted to sit on the panel if a hearing does result, it takes a scarce, experienced individual out of the judge pool. So I'm thinking a good compromise might be to offer the Post-Race penalty without the arbitration meeting - basically let the parties work it out between themselves (possibly with some informal advice from a knowledgeable person) and if the protestee thinks they're likely to lose or wants to avoid the risk of DSQ (or just doesn't want to sit through a hearing) they can volunteer to take a 30% scoring penalty. Presumably the protestor would then request to withdraw the protest.
Thinking about the following SI, wanted to see if you all have feedback:
"Arbitration will not be used. However, a boat protested for a breach of a rule of Part 2 or rule 31 in an incident not falling under RRS 44.1(b) may voluntarily accept a 30% Post-Race Penalty at any time after finishing but before a protest hearing for the incident has convened. If the protest is not withdrawn a hearing will be held, but if a boat has accepted a Post-Race Penalty RRS 64.1(b) will apply."
