General
• Deviation = 0°• Variation = 20°E• All positions and lines plotted on the chart should adhere
to labeling conventions in Supplementary Material• Use Piloting Training Chart C• Plot DRs
– every whole hour– whenever a change of speed or course– Whenever a bearing is taken or fix is obtained
• No wind or current• Show all work and calculations

When you reach Pringle Rock, you find a 5-metre runabout floating and not taking on water, but with a severely damaged outboard drive unit and propeller. The
operator, though unhurt, is very upset with himself for not exercising more care in his navigation. You fashion a towing bridle and begin the tow back to his cabin at
Roscoe Bay.
