You are reading draft marks on a vessel. The water level is halfway between the bottom of the number 5 and the top of the number 5. What is the draft of the vessel?
• Standard draft mark dimensions (height of the numbers and spacing between them) • How draft is read: from the bottom of the numeral representing whole feet • Relationship between inches and fractions of a foot on draft marks
• First, decide what draft (in feet) the bottom of the number 5 represents, and what draft the top of the same number represents, using the standard dimensions. • Once you know the draft at the bottom and at the top of the 5, ask yourself: what is the draft exactly halfway between those two points? • Compare that halfway value, converted to feet and inches, with the answer choices provided.
• Verify the standard height of a draft numeral and that this full height equals 6 inches of draft. • Confirm that draft is measured to the bottom of the numeral, not the center or the top. • Make sure your final draft in feet and inches matches one of the choices exactly before you select it.
