When a boat requests redress because of an incident she claims affected her score in a race, and thus in a series, the time limit for making the request is the time limit for the race, rather than a time limit based on the posting of the series results.

The phrase “seamanlike way” in the definition Room refers to boat-handling that can reasonably be expected from a competent, but not expert, crew of the appropriate number for the boat.

Attempting to distinguish between facts and conclusions in a protest committee's findings is sometimes unsatisfactory because findings may be based partially on fact and partially on a conclusion. A national authority can change a protest committee's decision and any other findings that involve reasoning or judgment, but not its findings of fact. A national authority may derive additional facts by logical deduction. Neither written facts nor diagrammed facts take precedence over the other. Protest committees must resolve conflicts between facts when so required by a national authority.

When two boats are running on opposite tacks, the starboard-tack boat may change course provided she gives the port-tack boat room to keep clear.

When the string representing a boat's track lies on the required sides of finishing marks or gate marks, it is not relevant that, when drawn taut, it also passes one of those marks on the non-required side.

During the starting sequence, a boat that is not keeping a lookout may thereby fail to do everything reasonably possible to avoid contact. Hailing is one way that a boat may “act to avoid contact”. When a boat's breach of a rule of Part 2 causes serious damage and she then retires, she has taken the applicable penalty and is not to be disqualified for that breach.

When taking a penalty after touching a mark, a boat need not complete a full 360° turn, and she may take her penalty while simultaneously rounding the mark. Her turn to round the mark will serve as her penalty if it includes a tack and a gybe, if it is carried out promptly after she is no longer touching the mark and is well clear of other boats, and when no question of advantage arises.

The IRPCAS or government right-of-way rules apply between boats that are racing only if the sailing instructions say so, and in that case all of the Part 2 rules are replaced. An IRPCAS or government rule may be made to apply by including it in the sailing instructions or in another document governing the event.
