Save fuel by slowing boat 



This graph shows the dramatic fuel savings that 

 are possible by reducing boat speeds. Most boat 

 owners know this fact, but this convenient graph 

 gives you a basis for a quick estimation of the 

 possible fuel savings and the amount of time that 

 must be sacrificed at the lower speed. 



To demonstrate the value of the graph: assume 

 a fisherman's boat is designed to make 10 knots 

 top speed (100 percent); if he operates at 8 knots 

 (80 percent of his top design speed), he would 

 consume only 50 percent of the fuel he would use 

 at 10 knots and run at 20 percent lower RPM, as 

 shown by the dotted lines on the graph. 



To read the graph, choose on the bottom line the 

 percentage of design speed to be used and run a 

 perpendicular line through both the propeller 

 RPM and fuel consumption curves. From the points 

 where this vertical line intersects these curves, 

 run horizontal lines at right angles and read the 

 percent of fuel reduction and RPM on the left-hand 

 scale.

Workshop to explain areas of environmental concern 



A workshop aimed at explaining the importance 

 of dunes, wetlands, estuaries and other unique 

 coastal features which may become "areas of en- 

 vironmental concern" under the state's Coastal 

 Area Management Act will be held March 5 at 

 East Carolina University's Mendenhall student 

 union. 



Sponsored by the UNC Sea Grant Program, the 

 workshop will feature university scientists who 

 have conducted research in environmentally sensi- 

 tive coastal areas. Program speakers will detail the 

 importance of dunes, wetlands and estuarine wat- 

 ers, as well as certain areas of social and historic 

 significance. According to program organizer Dr. 

 Simon Baker, UNC Sea Grant land-use advisory 

 agent, speakers will provide scientific background 



on why these areas require special attention. 



The conference, open to the public, should be 

 of special interest to county, municipal and state 

 officials involved in coastal planning. Under the 

 state's Coastal Area Management Act, lands and 

 waters where development would be unwise are 

 to be labeled "areas of environmental concern," 

 and development in these areas is to be closely 

 controlled. 



Keynote speaker for the workshop is Glenn J. 

 Akins, chief planner of Oregon's Coastal Conserva- 

 tion and Development Commission. Akins will 

 discuss Oregon's experiences in designating "areas 

 of particular concern" as called for in that state's 

 coastal management act.
