276. You have 550 tons of below deck tonnage including liquid mud. Your existing deck cargo is 120 tons with a VCG above the deck of 2.6 feet. What is the maximum additional deck cargo tonnage you are permitted to load

The maximum additional deck cargo is determined by the vessel's loading diagram, which limits total deck cargo to 240 tons with 550 tons of below-deck tonnage; therefore, the maximum additional cargo permitted is 120 tons (240 tons — 120 tons already loaded).
