🔍 Key Concepts

• Relationship between drafts forward and aft and overall trim by the stern • How to interpret LCF (Longitudinal Center of Flotation) location along the vessel’s length • Using the difference between forward and aft drafts over the vessel’s length to find trim

💭 Think About

• How much deeper is the stern than the bow, and what does that difference represent in terms of trim? • Given the vessel length is 180 feet, how does a 3-foot difference in draft from bow to stern translate into trim by the stern? • Is the longitudinal center of flotation (LCF) needed to solve this, or is the trim directly indicated by the change in drafts?

✅ Before You Answer

• Confirm which end (bow or stern) has the greater draft to identify whether the trim is by the bow or by the stern • Calculate the numerical difference between the bow and stern drafts before looking at the answer choices • Decide whether the LCF information changes the basic trim calculation, or if the trim is simply the draft difference between the two ends
