Marine Index Bureau (MIB), PWC, Coast Guard
During 1992–93, the Marine Index Bureau (MIB) Foundation conducted a study of boating accidents based on data from boating claims submitted to insurance companies. 10 Of the 104 identified insurers, MIB sampled data from 13 insurers that accounted for 61 percent of the total insured boating population at that time.
For 1992, MIB estimated that there were 95,849 reportable accidents based on insurance data; Coast Guard data indicate 6,048 reported accidents, or 6.3 percent of the MIB estimate. Comparisons of injury were much closer: MIB estimated 4,039 persons injured; the Coast Guard reported 3,683 (91 percent of the MIB estimate).
For accidents involving injury, the MIB and the Coast Guard appear to have similar data. Property damage accidents without injury may be reported to insurance companies but might not be reported on boating accident forms
