Q

The DEEP DRILLER departs a fresh water port at a draft of 20.5 feet. What will be the draft in sea water?

🔍 Key Concepts

• Fresh water vs. salt (sea) water density and how it affects draft • The idea of draft changes when moving between waters of different density • The standard conversion relationship between fresh water and salt water draft

💭 Think About

• When a vessel moves from fresh water to sea water, does it float deeper or shallower? Why? • Is the change in draft usually large or relatively small for typical draft values? • How can you use a simple ratio to adjust a fresh water draft to an equivalent salt water draft?

✅ Before You Answer

• Be clear about which draft is larger: fresh water or sea water, for the same displacement • Use the standard 1.025 specific gravity for sea water and 1.000 for fresh water in your thinking • Estimate the change: it should be proportional to the draft and less than a few feet for a 20.5‑foot draft
