This report describes the reasoning and logic which led to the development of a Safe Powering Test Procedure for Outboard boats. The present report is a companion document to the Safe Powering Test Procedure report, and the paragraph numbering corresponds to the paragraph numbering of the test procedure for ease of interpretation. The Safe Powering Test Procedure which has been developed is designed to determine whether or not a given boat complies with the Maximum Allowable Horsepower as specified in the Boating Safety Act of 1971, and the Rules and Regulations in the Federal Register, Vol. 37, No. 151, dated 4 August 1972. Basically the specifications of Maximum Allowable Horsepower is determined according to the length of the boat, the width and height of the transom, the characteristic hull shape and whether or not the particular boat has remote steering. Nomographs were developed for determining the Maximum Allowable Horsepower based upon the parameters listed above. The development of these nomographs, which greatly simplifies the determination of the Maximum Allowable Horsepower, is discussed in detail. (Author)
