About This Item

This SAE Recommended Practice establishes the procedure for measuring the maximum exterior sound level of pleasure motorboats while being operated under a wide open throttle condition or a maximum speed of 70 km/h (43.5 mph). It is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances. Changes in this Revision: The response on the A-weighted network was changed from “Fast” to “Slow”. This resolves the primary difference between ISO 14509 and this document and also reduces the erroneous/unrepeatable results obtained because of wave slaps to the hull. To avoid safety issues a conversion factor was added to convert sound level readings taken at 25 m (82.5 ft) to sound level readings at 15 m (50 ft). The high speeds achieved by today’s modern boats in many cases do not allow for a safe pass-by test at wide open throttle, consequently the specification for maximum boat speed during the pass-by test has been limited to 70 km/h (43.5 mph) which also agrees with ISO 14509. A relationship to this document and ISO 14509 was added.
