Question 1 of 2066636eec28f7522a1c51cc43

Your sailing drafts are: FWD 17'-07", AFT 18'-03" and the GM is 2.8 feet. What will be the angle of list if the #4 starboard double bottom (capacity 141 tons, VCG 2.6 feet, and 23.8 feet off the centerline) is filled with saltwater? (Use the data in Section 1, the blue pages, of the Stability Data Reference Book)

🔍 Key Concepts

• Transverse stability and list when an off-center weight is added • Using heeling moment = weight × transverse distance to find angle of list • Relating heeling moment to righting moment = Δ × GM × sin(θ)

💭 Think About

• From the given drafts and GM, how can you determine the vessel’s displacement Δ from the Stability Data Reference Book? • Once the starboard double bottom is filled, what is the total heeling moment created, and how does this relate to Δ × GM × sin(θ)? • After solving for sin(θ), what must you do to compare your result with the answer choices in degrees?

✅ Before You Answer

• Be sure you are using the correct displacement Δ for the initial drafts from the hydrostatic (blue page) data • Confirm that the weight of water in #4 DB uses the stated capacity and correct units (tons vs long tons) • Double‑check that you use GM in feet, transverse distance in feet, and convert the final angle from radians to degrees before matching to the choices
