🔍 Key Concepts

• Trim and draft calculations – how trim by the stern changes the forward and aft drafts • List and side drafts – how a list to port changes port vs. starboard drafts • Using the original drafts from Sample Load #5 as the starting point before discharge, trim, and list

💭 Think About

• From Sample Load #5, what was the original aft draft before discharging cargo? • If the vessel trims 3 feet by the stern, how does that numerically affect the aft draft compared to the mean draft? • With a 2-foot list to port, will the port aft draft be deeper or shallower than the starboard aft draft, and by about how much?

✅ Before You Answer

• Make sure you start from the correct original aft draft for Sample Load #5 before any changes. • Apply the trim by stern change correctly to the aft draft (not to the bow draft). • After applying trim, adjust for list to port so that the port aft draft is different from the starboard aft draft in the correct direction.
