🔍 Key Concepts

• Propeller pitch as theoretical distance advanced per revolution (in feet) • How to convert revolutions per day × pitch into total theoretical distance, then adjust for positive slip • Unit conversion from feet per day to nautical miles or statute miles

💭 Think About

• First, ignore slip: What total distance in feet would the vessel travel in one day if there were no slip? (Use pitch × rev/day.) • Next, apply 6% positive slip: does this mean the vessel travels more or less than the theoretical distance? How do you express that as a multiplier? • Finally, convert the corrected distance in feet into miles, then compare to the answer choices.

✅ Before You Answer

• Be clear whether the answer choices are in statute miles (5280 ft), not nautical miles (6076 ft). • Check that your slip adjustment direction is correct: positive slip vs negative slip. • After computing, do a quick reasonableness check: Is the distance consistent with the vessel moving roughly pitch × rev/day with a small (6%) correction?
