🔍 Key Concepts

• Trim is the difference between forward and aft drafts • Be careful with which draft you subtract from which so the sign (by the bow or by the stern) is correct • Convert any mixed numbers or decimals carefully when comparing to choices

💭 Think About

• How do you calculate trim when given a forward draft and an aft draft? Which one should you subtract from which? • If the aft draft is larger than the forward draft, is the vessel trimmed by the bow or by the stern? • Once you find the numerical difference in feet, which answer choice most closely matches that value?

✅ Before You Answer

• Confirm which draft is forward and which is aft before doing any math • Re-check your subtraction carefully to avoid simple arithmetic errors • Make sure your final wording (by the bow / by the stern) matches the physical situation described by the drafts
