Summary of Finishes, Abandonments, and Sinkings
* Boats were assigned to various classes not by their overall length but by their International Offshore Rule ratings, which are determined by a formula involving many speed-producing and speed-inhibiting factors and which are intended to indicate the potential speed of racing boats. When the race is over, the IOR ratings are factored against the boats’ elapsed times on the course to calculate corrected times, which are then compared to determine the overall standings. Since some large boats may have relatively low ratings and some small boats may have relatively large ratings, the “approximate size limits” only indicate the size range of the majority of boats in each class. For example, in Class III there were entered several forty-footers and one thirty-footer. The IOR limits for each class are assigned by the Royal Ocean Racing Club at the beginning of each racing season.
