This paper presents the results of SNAME Small Craft Panel SC-3 Fishing Systems investigation of trends in US fishing vessel with powering and NO(x) emissions (1900-2000). The study estimates the 1,299 vessels in the US fishing fleet produce 306 tons/day of NO(x). The largest powers are found in the decades of 1960-1980. The actual power kW\s compared to a reference power kWo using the Powering Index Ratio PIR = kW/kWo. It was found that 50 to 80% of the power in seiners, trawlers, and crabber/ trapper/clam vessels have PIR > 2.5. The reduction of fishing vessel diesel engine NO(x) can be best achieved by adopting acceptable levels of vessel power/length for the basis of revenue and tax rather than using the vessel age as emissions reduction criteria.
