🔍 Key Concepts

• Mean draft vs. draft at individual marks (how trim and list change drafts at bow/stern and port/starboard) • Effect of trim by the stern on forward vs. after drafts • Effect of list to port on port vs. starboard drafts

💭 Think About

• First, with a three-foot trim by the stern, is the forward draft more or less than the mean draft? By how much? • Then, with a two-foot list to port, will the starboard draft at that same end be deeper or shallower than the average on that end? • Combine the trim effect at the bow with the list effect at starboard to estimate the starboard forward draft.

✅ Before You Answer

• Be clear on the sign of each effect: stern trim increases stern draft and decreases bow draft; port list increases port draft and decreases starboard draft. • Apply the trim change before you apply the list change at that end. • Compare your final value with the mean draft (45 ft) and ask if it logically should be higher or lower given stern trim and port list.
