Question 1 of 2066636eec28f7522a1c51c207

Your drafts are: FWD 5'-11", AFT 6'-11". From past experience, you know that the vessel will increase her draft 1 inch for every 7 tons loaded. There is rig water on board and 16 tons of deck cargo. How many more tons of cargo can be loaded and still maintain the same trim? See illustration D037DG below.

🔍 Key Concepts

• Use the draft limits in the stability letter (maximum forward and aft drafts) and compare them with the present drafts. • Apply the given tons per inch immersion (TPI): 1 inch per 7 tons, assuming the ship sinks evenly (same trim). • Check the deck cargo limits when rig water is carried in restriction #4 of the letter.

💭 Think About

• How many inches of draft increase are available forward and aft before you hit the allowable maximums in item 2 of the letter? • If each 7 tons increases the draft 1 inch everywhere, which end (forward or aft) becomes the limiting factor, and how many tons does that allow? • Separately, with rig water already on board and 16 tons of deck cargo, how much deck cargo could you still add under item 4, and is that more or less restrictive than the draft limit you just found?

✅ Before You Answer

• Compute remaining inches of draft available forward and aft from the current drafts to the maximum allowed values in the letter. • Multiply the limiting inches (forward vs. aft) by 7 tons/inch to find the maximum additional cargo without exceeding drafts. • Verify that the resulting additional cargo does not exceed the deck cargo limit with rig water on board stated in item 4.
