🔍 Key Concepts

• Use the loading diagram D036DG: vertical axis is deck cargo (long tons), horizontal axis is below deck tonnage • Follow the USCG instructions on the diagram: draw a vertical line up from the given below‑deck tonnage, then a horizontal line across from the total deck cargo to compare with the safe‑loading curve • Remember that your existing deck cargo has a VCG of 2.6 ft, which must be within the maximum allowed VCG for deck cargo in the notes on the diagram

💭 Think About

• How do you find the maximum safe total deck cargo for 550 tons of below‑deck load by using the intersection with the safe‑loading curve? • Once you know the maximum total deck cargo at 550 tons below deck, what simple subtraction do you do to find the additional cargo you can still load? • Is the vessel operating in Zone I or Zone II on the diagram at 550 tons below deck, and does that affect how high up the curve you can go?

✅ Before You Answer

• Confirm you are reading long tons on both axes and using 550 tons below deck on the horizontal axis • Verify that the VCG limit for deck cargo (3.0 ft above deck) from the notes is not exceeded by the given 2.6 ft VCG • Make sure you base your answer on the maximum deck cargo at the curve for 550 tons, then subtract the existing 120 tons to get the remaining allowance
