Hooking rules designed to increase average turn volume by limiting the minimum volume yarded per turn were tested with a small skyline cable yarder. The test was conducted on a steep-slope Appalachian hardwood site, harvesting fuelwood from logging residue. Average volume per turn yarded increased from 10.0 to 12.3 ft³, increasing yarder production from 121 to 156 ft³ per hour, and reducing yarding cost from $22.74 per hundred ft³ to $17.75 per hundred ft³. These results demonstrate the feasibility of applying a simple set of hooking rules to improve the efficiency of smallwood harvesting operations. North. J. Appl. For. 4:33-35, March 1987.
